AFHTTPClient requestWithMethod ParameterEncoding

I want to use AFNetworking for a HTTP Post method with some parameters and two values have the same parameter. I tried out: 

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSDictionary *params = [NSDictionarydictionaryWithObjectsAndKeys: @"value1", @"param1", @"value2", @"param2", @"value3", @"param3", @"value4", @"param3", nil];
NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:@"/index.php" parameters:params];

I used Charles Proxy and figured out that the value4 was missing in my request.

Then I tried:

NSString *parameter = @"param1=value1&param2=value2&param3=value3&param3=value4";
[request setHTTPBody:[parameter dataUsingEncoding:NSUTF8StringEncoding]];

And this worked.

Now I want to know if I am doing something wrong with AFNetworking or is this a bug of AFNetworking?

Your issue is not with AFNetworking but with NSDictionary. You cannot have two entries with the same key.

In this case it means:

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: @"value1", @"param1", @"value2", @"param2", @"value3", @"param3", @"value4", @"param3", nil];

should be replaced the following

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: @"value1", @"param1", @"value2", @"param2", @"value3,value4", @"param3", nil];

Combining the two values for the one key.

Another way of combining arguments in one key is using a NSArray. For example:

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: @"value1", @"param1", @"value2", @"param2", [NSArray arrayWithObjects:@"value3",@"value4",nil], @"param3", nil];

Typo, use param4 not param3 for last key value.

NSDictionary *params = [NSDictionarydictionaryWithObjectsAndKeys: @"value1", @"param1", @"value2", @"param2", @"value3", @"param3", @"value4", @"param3", nil]

Corrected one

NSDictionary *params = [NSDictionarydictionaryWithObjectsAndKeys: @"value1", @"param1", @"value2", @"param2", @"value3", @"param3", @"value4", @"param4", nil]
