如何使用请求向php脚本发布请求并在目标C中发布变量

Question

I want to send a post request from objective-C code to a php script with URL

http://ggg.abc.com/example.php?MO&email=[e-mail]&message=TESTMSG&recipient=11111

I tried to use ASIFormDataRequest as below, but how do I specify the request variable MO in the request?

NSURL* url = [NSURL URLWithString:ServerApiURL];
ASIFormDataRequest* request = [ASIFormDataRequest requestWithURL:url];
[request setDelegate:self];

// Add the POST fields
//[request setPostValue:@"" forKey:@"MO"];
//[request setRequestMethod:@"MO"];

[request setPostValue:@"[e-mail]" forKey:@"email"]; 
[request setPostValue:@"TESTMSG" forKey:@"message"];
[request setPostValue:@"11111" forKey:@"recipient"];

Or any other way to do this?

As a last resort, -appendPostData: should work.

PUT requests and custom POSTs

---

If you want to send data via PUT, or want to send it with POST but prefer to create the POST body yourself, use appendPostData: or appendPostDataFromFile:.

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request appendPostData:[@"This is my data" dataUsingEncoding:NSUTF8StringEncoding]];
// Default becomes POST when you use appendPostData: / appendPostDataFromFile: / setPostBody:
[request setRequestMethod:@"PUT"];

If you want to send large amounts of data and aren’t using an ASIFormDataRequest, see the information on streaming post bodies from disk below.

For you this would be:

NSURL* url = [NSURL URLWithString:ServerApiURL];
ASIFormDataRequest* request = [ASIFormDataRequest requestWithURL:url];
[request setDelegate:self];
[request appendPostData:[@"MO&email=[e-mail]&message=TESTMSG&recipient=11111" dataUsingEncoding:NSUTF8StringEncoding]];

Good Luck

Update answer for lastest comment

NSURL* url = [NSURL URLWithString:ServerApiURL];
NSURL* urlWithParams = [NSURL URLWithString:@"?MO&email=[e-mail]&message=TESTMSG&recipient=11111" relativeToURL:url];
ASIFormDataRequest* request = [ASIFormDataRequest requestWithURL:urlWithParams];
[request setDelegate:self];
// Does this request need to be a post? If so, then call -setRequestMethod:.
// NOTE: I don't know if zero length posts work.
[request setRequestMethod:@"POST"];
