I am using IdHttp for a post and everything is working fine except for one thing. Here is the most basic example I can make of my problem. I want to replicate this form post...
<html>
<body>
<form method=post action=test.asp>
<input type=text name=testparam value="dog&cat+fish">
<input type=submit name=submit>
</form>
</body>
</html>
I have an ASP page that correctly displays the retrieved text string "dog&cat+fish" as posted by the above web page.
Here's some example asp...
Response.Write "<pre>"
Response.Write "testparam=" & Request.Form("testparam") & vbCRLF
The output from the ASP page when the above form is submitted is
dog&cat+fish
Now how do you do this with IdHttp ?
I have the post working fine, so long as the user doesn't use '+' or '&' in their string.
It is the correct encoding of the the string that I have a problem with.
var
PostData:TIdStrings
begin
...
PostData.Clear;
PostData.Add('testparam=dog&cat+fish');
Response := MyIdHttp.Post(URL, PostData);
end;
I have traced the code, and TIdURI.ParamsEncode(const ASrc: string): string; is being called,
however what it lists as unsafe parameter characters is ['*', '#', '%', '<', '>', ' ','[',']'] and does not include '&','+'
So my question is, rather than modifying TIdURI.ParamsEncode to add '&','+', what is the correct way to achieve what the browser does as standard ?
Thanks for any help.
Steve
