NSURLRequest：如何将httpMethod“GET”更改为“POST”(NSURLRequest: How to change httpMethod “GET” to “POST”)

GET方法，它工作正常。

网址： http : //myurl.com/test.html?query= id= 123& name= kkk

我没有POST方法的概念。请帮帮我。

如何将GET方法变为POST方法？

网址： http ： //testurl.com/test.html

[urlRequest setHTTPMethod:@"POST"];

GET Method, it works fine.

url: http://myurl.com/test.html?query=id=123&name=kkk

I do not have concepts of POST method. Please help me.

How can I chagne GET method to POST method?

url: http://testurl.com/test.html

[urlRequest setHTTPMethod:@"POST"];

尝试这个

NSString *post = [NSString stringWithFormat:@"username=%@&password=%@",username.text,password.text]; NSLog(@"%@",post); NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:[NSString stringWithFormat:@" server link here"]]]; [request setHTTPMethod:@"POST"]; NSString *json = @"{}"; NSMutableData *body = [[NSMutableData alloc] init]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"]; [request setHTTPBody:postData]; //get response NSHTTPURLResponse* urlResponse = nil; NSError *error = [[NSError alloc] init]; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; NSLog(@"Response Code: %d", [urlResponse statusCode]); if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300) { NSLog(@"Response: %@", result); }

try this

NSString *post = [NSString stringWithFormat:@"username=%@&password=%@",username.text,password.text]; NSLog(@"%@",post); NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:[NSString stringWithFormat:@" server link here"]]]; [request setHTTPMethod:@"POST"]; NSString *json = @"{}"; NSMutableData *body = [[NSMutableData alloc] init]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"]; [request setHTTPBody:postData]; //get response NSHTTPURLResponse* urlResponse = nil; NSError *error = [[NSError alloc] init]; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; NSLog(@"Response Code: %d", [urlResponse statusCode]); if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300) { NSLog(@"Response: %@", result); }
