iOS POST request with AFNetworking

Question

I am using AFNetworking to make a POST request to a web service

This is the JSON that I need to send-

{
   “LinkedTo” : {
                            “IndividualStakeholder” : “”,
                            “GroupedStakeholder” : “”,
                            “LandParcelStakeholder” : “”,
                            “Communications” : “”,
                            “Team” : “”,
                            “Issue” : “”,
                            “Event” : “”
                        }
   “userId” : 170,
   “projectId”: 12
}

This is the code I am using -

NSString *jsonData = [self JSONString:jsonData1];

The value in NSString *jsonData at this point is

{\\"LinkedTo\\":{\\"IndividualStakeholder\\":\\"\\",\\"GroupedStakeholder\\":\\"\\",\\"LandParcelStakeholder\\":\\"\\",\\"Communications\\":\\"\\",\\"Team\\":\\"\\",\\"Issue\\":\\"\\",\\"Event\\":\\"\\"},\\"userId\\":170,\\"projectId\\":4}

NSURL *url = [[NSURL alloc]initWithString:@"https://somedomain.com/"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc]initWithBaseURL:url];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                             jsonData, @"jsonText" , nil];
NSURLRequest *request = [httpClient requestWithMethod:@"POST" path:@"https://somedomain.com/api/stakeholders" parameters:params];

AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request 
    success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON){
        NSLog(@"Inside the success block %@",JSON);
    }
    failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON){
        NSLog(@"json text is: %@", JSON);
        NSLog(@"Request failed with error: %@, %@", error, error.userInfo);
    }];
[operation start];



-(NSString*)JSONString :(NSString*)aString{
    NSMutableString *s = [NSMutableString stringWithString:aString];
    [s replaceOccurrencesOfString:@"\"" withString:@"\\\"" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [s length])];
    [s replaceOccurrencesOfString:@"/" withString:@"\\/" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [s length])];
    [s replaceOccurrencesOfString:@"\n" withString:@"\\n" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [s length])];
    [s replaceOccurrencesOfString:@"\b" withString:@"\\b" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [s length])];
    [s replaceOccurrencesOfString:@"\f" withString:@"\\f" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [s length])];
    [s replaceOccurrencesOfString:@"\r" withString:@"\\r" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [s length])];
    [s replaceOccurrencesOfString:@"\t" withString:@"\\t" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [s length])];
    return [NSString stringWithString:s];
}

The error on the server is - Request format is unrecognized for URL unexpectedly ending in '/stakeholders'. Which is an error in asp.net throws when deserializing the posted JSON

The output I am receiving on the client is

Request failed with error: Error Domain=com.alamofire.networking.error Code=-1011 "Expected status code [number of indexes: 100 (in 1 ranges), indexes: (200-299)], got 500" UserInfo=0x8e95e60 {NSErrorFailingURLKey= https://somedomain.com/api/stakeholders , NSLocalizedDescription=Expected status code [number of indexes: 100 (in 1 ranges), indexes: (200-299)], got 500}, { NSErrorFailingURLKey = " https://somedomain.com/api/stakeholders "; NSLocalizedDescription = "Expected status code [number of indexes: 100 (in 1 ranges), indexes: (200-299)], got 500"; } 2013-02-25 11:03:44.669 NetworkPlugin[60069:c07]

Answer 1

Check out AFHTTPClient 's setParameterEncoding method with AFJSONParameterEncoding so the post will actually have a valid JSON HTTP body. Declared and commented here

Answer 2

我看到的是你发送","而不是诸如"15", "18"等值。尝试使用正确的JSONKit函数修改你的json数据。
