How to sent data in variable via POST and AFNetworking?

问题

I use this method:

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];

And I have response:

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

My requirements is to send login and password via POST in variable "data", but how can I sent this variable on my server if I send request via text in dictionary here?

回答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


}

I got this:

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);
}];
