PostURL

语法：string:=PostURL（"URL"，"content" [，time-out]）

说明：将指定内容发送到指定的URL，并返回结果字符串。参数time-out用于设置超时时间，默认值为30秒。如果不需要返回结果字符串，可以将time-out设置为“0”。该函数的执行影响到两个系统变量：IOStatus和IOMessage。

PostURL only works in a Web-packaged piece and not in runtime development.
PostURL supports the POST method and not the GET method. If you want to use
GET, use ReadExtFile() or ReadURL(). ReadURL only works in Authorware 5
Attain.
The script must return a value to Authorware.
The length of the URL is limited to 2K, the content is limited to 30K, and
the return string is limited to 32K.
If you get a returning 5006 error message, the URL is probably incorrect or a
value is not being returned.
The content argument does not refer to content type, but to the content that
you are sending to the script.
