AFNetworking Overload a Post Parameter
I am switching from ASIHTTPRequest to AFNetworking and am facing a problem.
I'm trying to get into the API with a request that overloads the post parameter. I previously used ASIFormDataRequest for this and used this code to update 3 IDs at the same time.
// ASIHTTPRequestCode
[request addPostValue:@"value1" forKey:@"id"];
[request addPostValue:@"value2" forKey:@"id"];
[request addPostValue:@"value3" forKey:@"id"];
Since AFNetworking uses NSDictionary to store key value pairs, it doesn't seem straightforward how to do it. Any ideas?

I can't immediately see a direct way to do this using AFNetworking, but it can be done.
If you look at the code for AFHTTPClient requestWithMethod
, you will see this line, which sets the request body to contain the parameters:
[request setHTTPBody:[AFQueryStringFromParametersWithEncoding(parameters, self.stringEncoding) dataUsingEncoding:self.stringEncoding]];
Basically, you can pass an empty dictionary in requestWithMethod
for parameters, then it returns, call it request setHTTPBody
yourself, composing the query string yourself, similar to how it does AFQueryStringFromParametersWithEncoding
.

You can create a request like this:
NSURL *url = [NSURL URLWithString:@"http://www.mydomain.com/"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSDictionary *postValues = [NSDictionary dictionaryWithObject:[NSString stringWithFormat:@"%@,%@,%@",@"value1",@"value2",@"value3"] forKey:@"id"];
NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:@"/path/to/your/page.php" postValues];

I ran into a similar problem but solved it by updating the url. I added parameters that I need to send using url and set "parameters to nil"
so the url became something like
server\url.htm?data=param1&data=param2&data=param3
and sent nil as paramDictionary
[request setHTTPBody:[AFQueryStringFromParametersWithEncoding(nil, self.stringEncoding) dataUsingEncoding:self.stringEncoding]];
