iOS AFNetworking GET/POST Parameters - ios

Question

I want to do a POST request with AFNetworking which contains GET and POST parameters.
I am using this code:
NSString *urlString = [NSString stringWithFormat:#"upload_stuff.php?userGUID=%#&clientGUID=%#",
#"1234",
[[UIDevice currentDevice] identifierForVendor].UUIDString];
NSString *newUrl = #"https://sub.domain.com";
NSURL *baseURL = [NSURL URLWithString:newUrl];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:baseURL];
[httpClient defaultValueForHeader:#"Accept"];
NSDictionary *getParams = [NSDictionary dictionaryWithObjectsAndKeys:
#"1234", #"userGUID",
[[UIDevice currentDevice] identifierForVendor].UUIDString, #"clientGUID",
nil];
NSDictionary *postParams = [NSDictionary dictionaryWithObjectsAndKeys:
[#"xyz" dataUsingEncoding:NSUTF8StringEncoding], #"FILE",
nil];
[httpClient postPath:urlString parameters:postParams success:^(AFHTTPRequestOperation *operation, id responseObject) {
}failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error retrieving data: %#", error);
}];
Now I have two questions:
How can I use BOTH GET and POST dictionaries in the same request? For the time, I am integrating the GET dictionary into the URL and using only the POST dictionary ([httpClient postPath:...])
I am getting an error from the server stating that the parameter "FILE" is missing. Unfortunately I can't examine any server logs (not my server). But using a standard NSURLConnection I was able to send requests with the FILE parameter to this server. So what is going wrong here?

Stackoverflow for you:
NSData* sendData = [self.fileName.text dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *sendDictionary = [NSDictionary dictionaryWithObject:sendData forKey:#"name"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:remoteUrl];
NSMutableURLRequest *afRequest = [httpClient multipartFormRequestWithMethod:#"POST"
path:#"/photos"
parameters:sendDictionary
constructingBodyWithBlock:^(id <AFMultipartFormData>formData)
{
[formData appendPartWithFileData:photoImageData
name:self.fileName.text
fileName:filePath
mimeType:#"image/jpeg"];
}
];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:afRequest];
[operation setUploadProgressBlock:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {
NSLog(#"Sent %d of %d bytes", totalBytesWritten, totalBytesExpectedToWrite);
}];
[operation setCompletionBlock:^{
NSLog(#"%#", operation.responseString); //Gives a very scary warning
}];
[operation start];

AFNetworking has no method to setup both GET and POST params.
You have to setup GET params to your url, and use [AFHTTPClient requestWithMethod:path:parameters:] setup POST params.
- (NSURLRequest *)requestForPath:(NSString *)path method:(NSString *)method
{
NSMutableString *pathWithGetParams = [NSMutableString stringWithString:path];
BOOL hasPathContainsQueryChar = [path rangeOfString:#"?"].location != NSNotFound;
[pathWithGetParams appendString:hasPathContainsQueryChar ? #"&" : #"?"];
for (id key in self.getArguments.allKeys)
{
if ([key isKindOfClass:[NSString class]])
{
NSString *value = self.getArguments[key];
if ([value isKindOfClass:[NSString class]])
{
[pathWithGetParams appendString:[[self class] urlEncode:key]];
[pathWithGetParams appendString:#"="];
[pathWithGetParams appendString:[[self class] urlEncode:value]];
[pathWithGetParams appendString:#"&"];
}
}
}
NSString *upperCaseMethod = [method uppercaseString];
BOOL isMethodInGet = [upperCaseMethod isEqualToString:#"GET"];
NSURLRequest *request = [[self shareAFClient] requestWithMethod:method
path:pathWithGetParams
parameters:isMethodInGet ? nil : self.postArguments];
return request;
}
+ (NSString *)urlEncode:(NSString *)stringToEncode
{
return [self urlEncode:stringToEncode usingEncoding:NSUTF8StringEncoding];
}
+ (NSString *)urlEncode:(NSString *)stringToEncode usingEncoding:(NSStringEncoding)encoding
{
return (__bridge_transfer NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,
(__bridge CFStringRef)stringToEncode,
NULL,
(CFStringRef)#"!*'\"();:#&=+$,/?%#[]% ",
CFStringConvertNSStringEncodingToEncoding(encoding));
}
+ (NSString*)urlDecode:(NSString *)stringToDecode
{
return [self urlDecode:stringToDecode usingEncoding:NSUTF8StringEncoding];
}
+ (NSString*)urlDecode:(NSString *)stringToDecode usingEncoding:(NSStringEncoding)encoding
{
return (__bridge_transfer NSString *) CFURLCreateStringByReplacingPercentEscapesUsingEncoding(NULL,
(__bridge CFStringRef)stringToDecode,
(CFStringRef)#"",
CFStringConvertNSStringEncodingToEncoding(encoding));
}
