send image along with other parameters with AFNetworking - ios

Question

I am updating an old application code which used ASIHTTPRequest with AFNetworking. In my case, I am sending a bench of data to API, these data are different types: Image and other.
Here is the code I adopt so far, implementing an API client, requesting a shared instance, prepare the params dictionary and send it to remote API:
NSMutableDictionary *params = [NSMutableDictionary dictionary];
[params setValue:#"Some value" forKey:aKey];
[[APIClient sharedInstance]
postPath:#"/post"
parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
//some logic
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
//handle error
}];
What would be the case when I want to add an image to the params dictionary?
With ASIHTTPRequest, I used to do the following:
NSData *imgData = UIImagePNGRepresentation(anImage);
NSString *newStr = [anImageName stringByReplacingOccurrencesOfString:#"/"
withString:#"_"];
[request addData:imgData
withFileName:[NSString stringWithFormat:#"%#.png",newStr]
andContentType:#"image/png"
forKey:anOtherKey];
I digged into AFNetworking documentation and found they appending the image in an NSMutableRequest like this:
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSData *imageData = UIImageJPEGRepresentation([UIImage imageNamed:#"avatar.jpg"], 0.5);
NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:#"POST" path:#"/upload" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFileData:imageData name:#"avatar" fileName:#"avatar.jpg" mimeType:#"image/jpeg"];
}];
How should I mix this together on a neat way to integrate my image data into the APIClient request? Thanx in advance.

I have used same AFNetworking to upload image with some parameter. This code is fine working for me. May be it will help out
NSData *imageToUpload = UIImageJPEGRepresentation(uploadedImgView.image, 1.0);//(uploadedImgView.image);
if (imageToUpload)
{
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:keyParameter, #"keyName", nil];
AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:#"http://------"]];
NSMutableURLRequest *request = [client multipartFormRequestWithMethod:#"POST" path:#"API name as you have" parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFileData: imageToUpload name:#"image" fileName:#"temp.jpeg" mimeType:#"image/jpeg"];
}];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSDictionary *jsons = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil];
//NSLog(#"response: %#",jsons);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
if([operation.response statusCode] == 403)
{
//NSLog(#"Upload Failed");
return;
}
//NSLog(#"error: %#", [operation error]);
}];
[operation start];
}
Good Luck !!

With AFNetworking 2.0.1 this code worked for me.
-(void) saveImage: (NSData *)imageData forImageName: (NSString *) imageName {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSString *imagePostUrl = [NSString stringWithFormat:#"%#/v1/image", BASE_URL];
NSDictionary *parameters = #{#"imageName": imageName};
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:#"POST" URLString:imagePostUrl parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:#"image" fileName:imageName mimeType:#"image/jpeg"];
}];
AFHTTPRequestOperation *op = [manager HTTPRequestOperationWithRequest:request success: ^(AFHTTPRequestOperation *operation, id responseObject) {
DLog(#"response: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
DLog(#"Error: %#", error);
}];
op.responseSerializer = [AFHTTPResponseSerializer serializer];
[[NSOperationQueue mainQueue] addOperation:op];
}
If JSON response is needed use:
op.responseSerializer = [AFJSONResponseSerializer serializer];
instead of
op.responseSerializer = [AFHTTPResponseSerializer serializer];
