AFNetworking Uploading a file

Question

Does any one have a full implementation of uploading a file using AFNetworking. I have found some code on the internet but it is incomplete. The code I have found is here:

AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://my.client.server.com"]];


NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
[parameters setObject:[fieldName text] forKey:@"field01_nome"];
[parameters setObject:[fieldSurname text] forKey:@"field02_cognome"];



NSMutableURLRequest *myRequest = [client multipartFormRequestWithMethod:@"POST" path:@"/Contents/mail/sendToForm.jsp" parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
    [formData appendPartWithFileData:myNSDataToSend mimeType:@"image/jpeg" name:@"alleagto"];
}];


AFHTTPRequestOperation *operation = [AFHTTPRequestOperation HTTPRequestOperationWithRequest:myRequest success:^(id object) {
    NSLog(@"Success");

} failure:^(NSHTTPURLResponse *response, NSError *error) {
    NSLog(@"Fail");

}];


[operation setUploadProgressBlock:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {
    NSLog(@"Sent %d of %d bytes", totalBytesWritten, totalBytesExpectedToWrite);

}];

queue = [[[NSOperationQueue alloc] init] autorelease];
[queue addOperation:operation];

I get errors on the following lines:

 [formData appendPartWithFileData:myNSDataToSend mimeType:@"image/jpeg" name:@"alleagto"];

At the myNSDataToSend.

And here:

AFHTTPRequestOperation *operation = [AFHTTPRequestOperation HTTPRequestOperationWithRequest:myRequest success:^(id object) {
    NSLog(@"Success");

} failure:^(NSHTTPURLResponse *response, NSError *error) {
    NSLog(@"Fail");

}];

The error is:

Class method '+HTTPRequestOperationWithRequest:success:failure' not found(return type defaults to 'id')

Any help on this and uploading with AFNetworks would be amazing.

Thanks.

Solution

First, make sure you have the latest version of AFNetworking downloaded.

AFHTTPRequestOperation +HTTPRequestOperationWithRequest:success:failure: was removed a few versions back. Instead, you can do [[AFHTTPRequestOperation alloc] initWithRequest:...] and then set the completionBlock with either the straight property accessor (operation.completionBlock = ^{...}), or with -setCompletionBlockWithSuccess:failure:. Keep in mind that completion blocks execute after the request has finished downloading.

As for the multipart form block, -appendWithFileData:mimeType:name was also removed a while back. The method you want is -appendPartWithFileData:name:fileName:mimeType:.

Make those two changes and everything should work.

Hmm, I am still (a) finding that method in AFHTTPClient.m and (b) getting a compile error. Except my error says "Declaration of anonymous class must be a definition." Where can I look to fix this?

@mattt, can I change content-type from multipart/form-data; to image/jpeg while uploading image using multipartFormRequestWithMethod method? Need ur help!

[mattt]

@AlmasAdilbek No. You're sending a multipart form with a JPEG part, not a JPEG by itself.

@mattt face the same question, looking for some function allow me to post one file.
