Syntax:

HTTPGet(URL, header line 1, header line 2)

Parameters:

URL: A string that represents an HTTP address that lets you retrieve an HTTP request. When a Magic xpa client is accessing a web server that requires a user name and password, the URL should be HTTP://User:Password@[URL].

You can also support secret names using: HTTP://%user_secretname%:%pass_secretname%@[URL]

Header lines: A string that provides additional request header information. You may specify as many header information strings as you need.

Returns:

BLOB data – The actual file retrieved using the URL. If the function fails to make the connection, a blank value is returned.

Example:

HTTPGet('http://www.magicsoftware.com/idex.html', 'If-Modified-Since: Tue, 7 Aug 2001 12:00:00 GMT', 'User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0)')

This example requests the file specified by the first parameter. The following parameters are samples of additional request header information.

The first parameter asks to retrieve the page only if it was modified after the provided date.

The second parameter provides the server with the type of user agent that this request simulates.

Note:

• The HTTPGet function may connect through a proxy server. You can define your proxy server in the Magic.ini file or in the HTTP Proxy – Address Port environment setting.

• Use the HTTP Framework setting to define the underlying infrastructure.

• The retrieval phase of the function can be set to stop by specifying the HTTP Timeout environment setting in the Magic.ini file.

• When an HTML file or any textual data is retrieved, you may query the returned text stream using all the available string manipulation functions.

• Use the Blb2File function to store the retrieved file on your disk.

• When the data contains special characters (e.g. %,&,<,>…), if you do not want the data translated, then include 'content-type: text/html' in the HTTP header of the request.

• The URL address is automatically encoded.

• If there is a @ character in the URL, such as 'HTTP://myser:mypassword@myserver', only the address after the @ character will be encoded.

• If the URL contains @ and you need to encode it all (and not just the part after the @), you should add @ as the first character in the URL. For example: '@http://myserver@data'. In this case, the entire URL will be encoded and the first @ character will automatically be removed. Since version: 3.1
