如果是NSMutableURLRequest 要在请求加入各种字段其中包括

NSMutableURLRequest *request =[NSMutableURLRequestrequestWithURL:[NSURLURLWithString:URL]];

//设置发送请求的方式

[request setHTTPMethod:@"POST"];

//设置请求体

[request addValue:@"application/x-www-form-urlencoded"forHTTPHeaderField:@"Content-type"];

//设置参数

NSString *body =[NSStringstringWithFormat:@"username=%@&password=%@&email=%@",UsernameTextField.text,PasswordTextField.text,emailTextField.text];

//计算参数的总长度

int length =[bodylengthOfBytesUsingEncoding:NSUTF8StringEncoding];

//添加字段 Content-Lenth该字段的大小事参数集合的总长度和URL没有关系

[request addValue:[NSStringstringWithFormat:@"%d",length]forHTTPHeaderField:@"Content-Length"];

NSData *data =[bodydataUsingEncoding:NSUTF8StringEncoding];

//设置请求体

[request setHTTPBody:data];

//发送请求

_connection =[[NSURLConnectionalloc]initWithRequest:requestdelegate:self];

如果是ASIHTTP的话直接使用

ASIFormDataRequest *request1 =[ASIFormDataRequestrequestWithURL:[NSURLURLWithString:@"http://119.255.38.178:8089/sns/my/login.php"]];

request1.delegate=self;

//Key 是来自开发文档

[request1 addPostValue:@"test"forKey:@"username"];

[request1 addPostValue:@"123456"forKey:@"password"];

[request1 startAsynchronous];
