CURLNMBS.Perform as Integer
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 9.8 Yes Yes Yes Yes No
Function: Perform a file transfer
Notes:
This function is called after all the options are set, and will perform the transfer as described in the options.

You can do any amount of calls to Perform. If you intend to transfer more than one file, you are even encouraged to do so. libCURL will then attempt to re-use the same connection for the following transfers, thus making the operations faster, less CPU intense and using less network resources. Just note that you will have to use the option properties between the invokes to set options for the following Perform.

Typical error codes are 6 for a wrong domain name in the URL, 67 for wrong name/password combination, 60 for missing SSL settings, 1 for an unsupported protocol.

CURLNMBS.PerformMT as Integer
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 11.2 Yes Yes Yes Yes No
Function: Perform a file transfer with preemptive multithreading.
Notes:
Same as Perform, but with additional multithreading.
Must be called inside a Xojo (Real Studio) thread so time yields to main thread and you can keep the GUI running.

As the actual transfer runs on a preemptive thread, the events Debug, Write, Header and Progress are called asynchrounously and run a few milliseconds later. You can return true in Progress event to stop transfer, but you will get more events before the transfer is stopped.

You can call CreateMTDebugOutputFile, CreateMTHeaderOutputFile and CreateMTOutputFile before PerformMT to have output data be written into files. Call OpenMTInputFile to let the plugin read input data (form post or upload) from an input file.

Do not call other CURL functions on this CURLNMBS instance while PerformMT is running!

Typical error codes are 6 for a wrong domain name in the URL, 67 for wrong name/password combination, 60 for missing SSL settings, 1 for an unsupported protocol.

To avoid trouble with app hanging on quit of application, be sure to set cancel property to true in window close event to cancel any pending transfer.

CURLNMBS.ReceiveData(byref data as Memoryblock, BytesToRead as Int64) as Int64
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 17.2 Yes Yes Yes Yes No
Function: Receives raw data on a connection.
Notes:
This function receives raw data from the established connection. You may use it together with SendData to implement custom protocols using libcurl. This functionality can be particularly useful if you use proxies and/or SSL encryption: libcurl will take care of proxy negotiation and connection set-up.

The data memoryblock is a reference to your variable that will get the received data. BytesToRead is the maximum amount of data you can get in that buffer. The function returns the number of received bytes.

To establish the connection, set OptionConnectOnly = true before calling Perform. Note that ReceiveData does not work on connections that were created without this option.

The call will return kError_AGAIN if there is no data to read - the socket is used in non-blocking mode internally. When kError_AGAIN is returned, wait for data to arrive.

Wait on the socket only if ReceiveData returns kError_AGAIN. The reason for this is libcurl or the SSL library may internally cache some data, therefore you should call ReceiveData until all data is read which would include any cached data.

Furthermore if you wait on the socket and it tells you there is data to read, ReceiveData may return CURLE_AGAIN if the only data that was read was for internal SSL processing, and no other data is available.

On success, sets lasterror to kError_OK (0), stores the received data into memory block, and returns the number of bytes it actually read.

On failure, returns zero and lasterror is set to the appropriate error code.

The function may return kError_AGAIN. In this case, use your operating system facilities to wait until data can be read, and retry.

Reading exactly 0 bytes indicates a closed connection.

If there's no socket available to use from the previous transfer, this function returns kError_UNSUPPORTED_PROTOCOL.

CURLNMBS.Reset
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 9.8 Yes Yes Yes Yes No
Function: Re-initializes all options previously set on a specified CURL handle to the default values.
Notes: It does not change the following information kept in the handle: live connections, the Session ID cache, the DNS cache, the cookies and shares.

CURLNMBS.SendData(data as Memoryblock) as Integer
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 15.2 Yes Yes Yes Yes No
Function: Sends raw data over a connection.
Notes:
This function sends arbitrary data over the established connection. You may use it together with ReceiveData to implement custom protocols using libcurl. This functionality can be particularly useful if you use proxies and/or SSL encryption: libcurl will take care of proxy negotiation and connection set-up.

Provide the data to send via parameter. We return the number of bytes sent.

To establish the connection, set OptionConnectOnly = true option before calling Perform methods. Note that SendData will not work on connections that were created without this option.

The call will return kError_AGAIN if it's not possible to send data right now - the socket is used in non-blocking mode internally. When kError_AGAIN is returned, please wait.

Furthermore if you wait on the socket and it tells you it's writable, SendData may return kError_AGAIN if the only data that was sent was for internal SSL processing, and no other data could be sent.

Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 14.0 Yes Yes Yes Yes No
Function: Sets the input data.
Notes:
If you set input data, you do not need to use Read, RestartRead or Seek events.
The plugin will use the provided data for the upload.
Setting input data size, will also set the input file size (OptionInFileSizeLarge and OptionInFileSize).

Alternatively you can provide data in Read event or use OpenMTInputFile method to open a file on disk to upload.

CURLNMBS.SetOptionHTTP200Aliases(data() as string)
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 9.8 Yes Yes Yes Yes No
Function: A linked list of aliases to be treated as valid HTTP 200 responses.
Notes:
Some servers respond with a custom header response line. For example, IceCast servers respond with "ICY 200 OK". By including this string in your list of aliases, the response will be treated as a valid HTTP header line such as "HTTP/1.0 200 OK".

The alias itself is not parsed for any version strings. So if your alias is "MYHTTP/9.9", LibCURL will not treat the server as responding with HTTP version 9.9. Instead LibCURL will use the value set by option HTTPVersion.

The Lasterror property is set. 0 for success.

CURLNMBS.SetOptionHTTPHeader(data() as string)
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 9.8 Yes Yes Yes Yes No
Function: A linked list of HTTP headers to pass to the server in your HTTP request.
Example:
dim c as new CURLNMBS
c.SetOptionHTTPHeader array("Expect:", "Content-Type: text/xml", "SOAPAction: ""login""")
Notes:
If you add a header that is otherwise generated and used by libCURL internally, your added one will be used instead. If you add a header with no contents as in 'Accept:' (no data on the right side of the colon), the internally used header will get disabled. Thus, using this option you can add new headers, replace internal headers and remove internal headers. To add a header with no contents, make the contents be two quotes: "". The headers included in the linked list must not be CRLF-terminated, because CURL adds CRLF after each header item. Failure to comply with this will result in strange bugs because the server will most likely ignore part of the headers you specified.

The first line in a request (containing the method, usually a GET or POST) is not a header and cannot be replaced using this option. Only the lines following the request-line are headers. Adding this method line in this list of headers will only cause your request to send an invalid header.

Pass an empty array to this to reset back to no custom headers.

The Lasterror property is set. 0 for success.

ws.Append "RNFR Temp.txt"
ws.append "RNTO MyFile.txt"
d.SetOptionPostQuote(ws)
Notes:
Disable this operation again by using an empty array for this option.

The Lasterror property is set. 0 for success.
If you want to do a ftp operation instead of download/upload/directory listing, please use SetOptionQuote.

Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 9.8 Yes Yes Yes Yes No
Function: Pass an array to a list of FTP commands to pass to the server after the transfer type is set.
Notes:
Disable this operation again by using an empty array for this option. Before version 7.15.6, if you also set Nobody to true, this option didn't work.

The Lasterror property is set. 0 for success.

CURLNMBS.SetOptionQuote(data() as string)
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 9.8 Yes Yes Yes Yes No
Function: Pass an array or a list of FTP commands to pass to the server prior to your ftp request.
Example:
dim curl as new CURLNMBS
curl.SetOptionQuote array("DELE filename.txt")
Notes:
This will be done before any other FTP commands are issued (even before the CWD command).

Disable this operation again by using an empty array for this option.

CURLNMBS.SetOptionTelnetOptions(data() as string)
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 9.8 Yes Yes Yes Yes No
Function: Provide an array of variables to pass to the telnet negotiations.
Notes:
The variables should be in the format <option=value>. libCURL supports the options 'TTYPE', 'XDISPLOC' and 'NEW_ENV'. See the TELNET standard for details.

CURLNMBS.SetPathCAInfo(path as folderitem)
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 10.0 Yes Yes Yes Yes No
Function: A path holding one or more certificates to verify the peer with.
Example:
dim cacert as FolderItem // your cacert.pem file
dim CURL as new CURLMBS
CURL.OptionSSLVerifyHost = 2 // verify server
CURL.OptionSSLVerifyPeer = 1 // proofs certificate is authentic
CURL.SetPathCAInfo cacert
Notes:
This makes sense only when used in combination with the OptionSSLVerifyPeer option. If OptionSSLVerifyPeer is false, OptionCAINFO need not even indicate an accessible file.

Note that option is by default set to the system path where libCURL's cacert bundle is assumed to be stored, as established at build time.

The Lasterror property is set. 0 for success.
You can set this value and later you can read it, but you cannot read the default value.

CURLNMBS.SetPathCAPath(path as folderitem)
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 10.0 Yes Yes Yes Yes No
Function: A path to the directory holding multiple CA certificates to verify the peer with.
Notes:
The certificate directory must be prepared using the openssl c_rehash utility. This makes sense only when used in combination with the CURLOPT_SSL_VERIFYPEER option. If OptionSSLVerifyPeer is zero, OptionCAPath need not even indicate an accessible path. The OptionCAPath function apparently does not work in Windows due to some limitation in openssl. This option is OpenSSL-specific and does nothing if libCURL is built to use GnuTLS.

The Lasterror property is set. 0 for success.
You can set this value and later you can read it, but you cannot read the default value.

CURLNMBS.SetPathCRLFile(path as folderitem)
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 10.0 Yes Yes Yes Yes No
Function: Sets the path with the concatenation of CRL (in PEM format) to use in the certificate validation that occurs during the SSL exchange.
Notes:
When CURL is built to use NSS or GnuTLS, there is no way to influence the use of CRL passed to help in the verification process. When libCURL is built with OpenSSL support, X509_V_FLAG_CRL_CHECK and X509_V_FLAG_CRL_CHECK_ALL are both set, requiring CRL check against all the elements of the certificate chain if a CRL file is passed.

This option makes sense only when used in combination with the OptionSSLVerifyPeer option.

A specific error code (CURLE_SSL_CRL_BADFILE) is defined with the option. It is returned when the SSL exchange fails because the CRL file cannot be loaded. Note that a failure in certificate verification due to a revocation information found in the CRL does not trigger this specific error. (Added in 7.19.0)

CURLNMBS.SetPathIssuerCert(path as folderitem)
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 10.0 Yes Yes Yes Yes No
Function: Sets the path to a CA certificate in PEM format.
Notes:
If the option is set, an additional check against the peer certificate is performed to verify the issuer is indeed the one associated with the certificate provided by the option. This additional check is useful in multi-level PKI where one needs to enforce that the peer certificate is from a specific branch of the tree.

This option makes sense only when used in combination with the OptionSSLVerifyPeer option. Otherwise, the result of the check is not considered as failure.

A specific error code (CURLE_SSL_ISSUER_ERROR) is defined with the option, which is returned if the setup of the SSL/TLS session has failed due to a mismatch with the issuer of peer certificate (OptionSSLVerifyPeer has to be set too for the check to fail). (Added in 7.19.0)

CURLNMBS.SetPathNetRCFile(path as folderitem)
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 10.0 Yes Yes Yes Yes No
Function: Sets the path to the file you want libCURL to use as .netrc file.
Notes:
If this option is omitted, and OptionNETRC is set, libCURL will attempt to find the a .netrc file in the current user's home directory. (Added in 7.10.9)

The Lasterror property is set. 0 for success.
You can set this value and later you can read it, but you cannot read the default value.

CURLNMBS.SetupEmail(email as Variant) as boolean
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method CURL MBS CURL Plugin 14.3 Yes Yes Yes Yes No
Function: Setups existing CURL session for an email transfer.
Example:
dim e as new CURLEmailMBS

e.SetFrom "test@test.test", "Christian Müller"
e.Subject = "Hello World ☺️"
e.SMTPPassword = "xxx"
e.SMTPUsername = "xxx"
e.SetServer "smtp.test.test", true
e.AddTo "test@test.test", "Test Müller"
e.PlainText = "Hello World," + EndOfLine + "Smilies: ☺️ 😘 😄"

dim c as new CURLNMBS

if c.SetupEmail(e) then

dim er as Integer = c.Perform
if er = 0 then
MsgBox "Email sent"
end if
end if
Notes:
You can set your own settings like proxy after this function call.
If you like you can reuse the email and CURL objects after you sent an email, change values and send another email.
Returns true on success or false on failure.
