Alamofire post request with body in swift

Question

I'm trying to make post request with alamofire with body, but I keep having this error code "Message: An error has occurred." I run the same api in obj-c and afnetworking, all works fine. Am I using the wrong way to make parameters?

let parameters: [String: Any] = ["ID": "aaaa@test.com", "PW": "12345", "LoginType": "IDPW", "PushKey": "ios"]
Alamofire.request(loginApi, method: .post, parameters: parameters, encoding: JSONEncoding.default)
            .responseJSON { response in
                print(response)
        }

Body i send using Objective-C & function

     NSDictionary *parameters = @{
                             @"LoginType": @"IDPW",
                             @"ID": @"aaaa@test.com",
                             @"PW": @"12345",
                             @"PushKey":  @"ios"
                             };
     - (void) AsyncHttpRequestWithMethod:(NSString * _Nonnull)method
                      URLString:(NSString * _Nonnull)URLString
                     parameters:(NSDictionary * _Nullable)parameters
                        headers:(NSDictionary * _Nullable)headers
                 uploadProgress:(nullable void (^)(NSProgress * _Nullable uploadProgress)) uploadProgressBlock
               downloadProgress:(nullable void (^)(NSProgress * _Nullable downloadProgress)) downloadProgressBlock
              completionHandler:(nullable void (^)(NSURLResponse * _Nullable response, id _Nullable responseObject,  NSError * _Nullable error))completionHandler {

AFURLSessionManager *manager = [[AFURLSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

NSMutableURLRequest *req = [[AFHTTPRequestSerializer serializer] requestWithMethod:method URLString:URLString parameters:parameters error:nil];

req.timeoutInterval = intTimeInterval;

if (headers && headers.count > 0) {
    NSArray *keys = headers.allKeys;
    for (int i = 0; i < headers.count; i ++) {
        [req addValue:headers[keys[i]] forHTTPHeaderField:keys[i]];
    }
}

[[manager dataTaskWithRequest:req uploadProgress:^(NSProgress * _Nonnull uploadProgress) {
    if (uploadProgressBlock) uploadProgressBlock(uploadProgress);
} downloadProgress:^(NSProgress * _Nonnull downloadProgress) {
    if (downloadProgressBlock) downloadProgressBlock(downloadProgress);
} completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {

    NSLog(@"completionHandler......");

    completionHandler(response, responseObject, error);
}] resume];

}

I think you are missing the "Content-Type" header. have you mentioned it anywhere? — Shruti, Feb 22 '19 at 04:07

@Brandon I send nsdictionary in Objective-C. I've edit my question — fritz, Feb 22 '19 at 05:04
@Shruti I add headers: HTTPHeaders = ["Content-Type":"application/json"] in my code still not working — fritz, Feb 22 '19 at 05:06
but you need to pass headers in request also. after encoding header paramter should also come — Shruti, Feb 22 '19 at 05:07
@fritz here is working code https://stackoverflow.com/a/52312239/10150796 please check — Nikunj Kumbhani, Feb 22 '19 at 05:09
parameter keys are different in Obj-C and swift codes (ID vs MemberID, PW vs MemberPW). if the request succeeds(200 status code) and you are still seeing error response from api, this might be the problem. — Akhilrajtr, Feb 22 '19 at 05:19
@NikunjKumbhani I've tried ur code, still getting Message = "An error has occurred."; — fritz, Feb 22 '19 at 05:19
@Akhilrajtr That's what I thought. But i can't figure out how to make parameters working in swift — fritz, Feb 22 '19 at 05:23
@fritz parameter variable look good to me, did you tried making them same as in Obj-C? — Akhilrajtr, Feb 22 '19 at 05:25
@fritz parameters are right one more thing make sure that is there any special key define from the server side to pass parameters on that key. — Nikunj Kumbhani, Feb 22 '19 at 05:26
@NikunjKumbhani I think sever is working, i use other obj-c project to run the api and parameters. It's working. Can I share my request API privately for u ? I'm new to this. — fritz, Feb 22 '19 at 05:31
@Akhilrajtr Yes. I use same key and value like i use in obj-c. — fritz, Feb 22 '19 at 05:32
@fritz i have already say to share this in my previous comment. and also update ypur obj-c api call code in question. — Nikunj Kumbhani, Feb 22 '19 at 05:38
@fritz Your request parameters different in objective-c and swift code. — Nikunj Kumbhani, Feb 22 '19 at 05:58

In your request headers is missing, Please use the following code to get the result.

let headers = ["Content-Type":"application/json"]    
let parameter = ["MemberID": "aaaa@test.com", "MemberPW": "12345", "LoginType": "IDPW", "PushKey": "ios"]

            Alamofire.request(loginApi, method: .post, parameters: parameter, encoding: JSONEncoding.default, headers: headers)
                .responseJSON { (response) in
                    switch response.result {
                    case .success:
                        print("success",response)
                    case .failure(let error):
                        print("failure",error)
                    }
            }

I add headers in the request and still getting SUCCESS: { Message = "An error has occurred."; } – fritz Feb 22 '19 at 05:11
Okay you API call is getting response success block, but there is some issue may occur from API side. – AtulParmar Feb 22 '19 at 05:19

Your codes looks good to me.

Without more information it is difficult to identity that what is actual problem.

As per me possible problem is encoding

change

JSONEncoding.default

with other available options like URLEncoding.default

Let me know if it is not working then I will delete my answer
