如何通过POST和AFNetworking在变量中发送数据？

我用这个方法：

NSDictionary *params = @{@"email" : email, @"password" : pass }; NSString* HOST_URL = @"http://server.com:8080"; AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:HOST_URL]]; NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:@"/login" parameters:params]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; [httpClient registerHTTPOperationClass:[AFHTTPRequestOperation class]]; [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"Response: %@", [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]); NSDictionary *response = (NSDictionary*)[NSJSONSerialization JSONObjectWithData:operation.responseData options:kNilOptions error:nil]; //HERE YOU HAVE A RESPONSE (your server answer) } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error.localizedDescription); }]; [operation start]; 

我有回应：

 {"Result":"fail","Message":"unexpected end of JSON input","Data":null} 

我的要求是通过POST在变量“data”中发送登录名和密码，但是如果我通过字典中的文本发送请求，如何在我的服务器上发送此变量？

Answer 1

 NSDictionary *params = @{@"email" : email, @"password" : pass }; NSString* HOST_URL = @"http://server.com:8080"; AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager]; [operationManager POST:HOST_URL parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject){ // Enter what happens here if successsful. }failure:^(AFHTTPRequestOperation *operation, NSError *error){ // Enter what happens here if failure happens } 

Answer 2

我懂了：

 NSString *URLString = @"http://server.com:8080/login"; // login = @"user1@1q2w3e"; // user1@1q2w3e user3@frcity // password = @"1q2w3e"; NSString* data = @"{\"email\": \"user1@1q2w3e\" ,\"password\": \"1q2w3e\"}"; AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.requestSerializer = [AFHTTPRequestSerializer serializer]; NSDictionary *params = @{@"data" : data}; [manager POST:URLString parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"JSON: %@", responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error); }];
