Uploading image with AFNetworking 2.0 - ios

Question

I'm banging my head against the wall with this one. I want to select UIImage from library and upload it to server, like on could do with <form action="http://blabla.request.cfm" method="post" enctype="multipart/form-data">. Instead of success I got this error:
error = Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x145e5d90 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}
I tried this way:
-(void)uploadPhoto{
NSString *path = #"http://blabla.request.cfm";
NSData *imageData = UIImageJPEGRepresentation(self.imageView.image, 0.9);
int priv = self.isPrivate ? 1 : 0;
NSDictionary *parameters = #{#"username": self.username, #"password" : self.password, #"private" : #(priv), #"photo" : imageData};
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:path parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
if(self.imageView.image){
[formData appendPartWithFileData:imageData name:#"avatar" fileName:#"avatar.jpg" mimeType:#"image/jpeg"];
}
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"[UploadVC] success = %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"[UploadVC] error = %#", error);
}];
[self blockView:self.view block:YES];
}
but it's not working... server says that there is no file. Not sure if encrypting is wrong, mime type or what?
Tried also this:
[manager POST:path parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"[UploadVC] success = %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"[UploadVC] error = %#", error);
}];
and this:
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:path parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFormData:imageData name:#"photo"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"[UploadVC] success = %#", responseObject);
[self blockView:self.view block:NO];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"[UploadVC] error response.object = %#", operation.responseObject);
[self blockView:self.view block:NO];
}];
nothing is working. Hope someone can help, 'cause I'm stuck with it and circling from question to question here on SO

EDIT: new attempt
1) first was multi-part form
2) creating upload task
none of them worked for me, so I'm still trying to cope with that, but cannot see any solution

Answer 1

I'm not sure which part (I think that some details were missing) was responsible, but I did it finally :) here you go:
-(void)uploadPhoto{
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:#"http://server.url"]];
NSData *imageData = UIImageJPEGRepresentation(self.avatarView.image, 0.5);
NSDictionary *parameters = #{#"username": self.username, #"password" : self.password};
AFHTTPRequestOperation *op = [manager POST:#"rest.of.url" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
//do not put image inside parameters dictionary as I did, but append it!
[formData appendPartWithFileData:imageData name:paramNameForImage fileName:#"photo.jpg" mimeType:#"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %# ***** %#", operation.responseString, responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %# ***** %#", operation.responseString, error);
}];
[op start];
}
Works like a charm :)

You can upload an image with AFNetworking using Swift like this...
let compression = 0.5
let imageData = UIImageJPEGRepresentation("image", CGFloat(compression))
if imageData != nil{
var manager = AFHTTPRequestOperationManager()
manager.responseSerializer.acceptableContentTypes = NSSet(array: ["text/html", "application/json"]) as Set<NSObject>
var dictParams = [
"familyId":"10000",
"contentBody" : "Some body content for the test application",
"name" : "the name/title",
"typeOfContent":"photo"
]
let url = "http://...."
manager.POST(url, parameters: dictParams, constructingBodyWithBlock: { (formData: AFMultipartFormData!) -> Void in
//code
formData.appendPartWithFileData(imageData, name: "file", fileName: "filename", mimeType: "image/png")
}, success: { (operation:AFHTTPRequestOperation!, responseObject:AnyObject!) -> Void in
println(responseObject)
}, failure: { (operation:AFHTTPRequestOperation!, error:NSError!) -> Void in
println(error)
})
}

UIImage *image = [UIImage imageNamed:#"decline_clicked.png"];
NSData *imageData = UIImageJPEGRepresentation(image,1);
NSString *queryStringss = [NSString stringWithFormat:#"http://your server/uploadfile/"];
queryStringss = [queryStringss stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"text/html"];
[manager POST:queryStringss parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
[formData appendPartWithFileData:imageData name:#"fileName" fileName:#"decline_clicked.png" mimeType:#"image/jpeg"];
}
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSDictionary *dict = [responseObject objectForKey:#"Result"];
NSLog(#"Success: %# ***** %#", operation.responseString, responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"Error: %# ***** %#", operation.responseString, error);
}];
