How to Upload Multipart data of image in base64 Using afnetworking - ios

Question

I have used the following code but the response which i get is java.lang.NullPointerException & INTERNAL_SERVER_ERROR I tried many different methods but unable to fix it please help in fixing this.
Getting the Image from the Image picker
UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
Profilebackground.image = chosenImage;
[picker dismissViewControllerAnimated:YES completion:NULL];
NSURL *resourceURL;
UIImage *image =[[UIImage alloc] init];
image =[info objectForKey:#"UIImagePickerControllerOriginalImage"];
NSURL *imagePath = [info objectForKey:#"UIImagePickerControllerReferenceURL"];
imageName = [imagePath lastPathComponent];
resourceURL = [info objectForKey:UIImagePickerControllerReferenceURL];
NSString *extensionOFImage =[imageName substringFromIndex:[imageName rangeOfString:#"."].location+1 ];
if ([extensionOFImage isEqualToString:#"JPG"])
{
imageData =UIImageJPEGRepresentation(image, 1.0);
base64 = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
extension=#"image/jpeg";
}
else
{
imageData = UIImagePNGRepresentation(image);
base64 = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
extension=#"image/png";
}
int imageSize=imageData.length/1024;
NSLog(#"imageSize--->%d", imageSize);
if (imageName!=nil) {
NSLog(#"imageName--->%#",imageName);
}
else
{
NSLog(#"no image name found");
}
Send the Image to server
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:#"https://blahblahblah.com/uploadProfileImg?userId=1" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
//NSData *pngData = [[NSData alloc] initWithBase64EncodedString:base64 options:1];
[formData appendPartWithFileData:imageData
name:#"key"
fileName:imageName mimeType:extension];
} success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(#"Response: %#", responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSHTTPURLResponse *response = (NSHTTPURLResponse *)task.response;
NSLog(#"error: %#",error);
// NSHTTPURLResponse *response = (NSHTTPURLResponse *)operation.response;
NSLog(#"statusCode: %ld", (long)response.statusCode);
NSString* ErrorResponse = [[NSString alloc] initWithData:(NSData *)error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] encoding:NSUTF8StringEncoding];
NSLog(#"Error Response:%#",ErrorResponse);
}];

Answer 1

You can just use the appendPartWithFileData:name:fileName:mimeType: method of the AFMultipartFormData class.
For instance:
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager POST:#"https://blahblahblah.com/imageupload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData
name:#"key name for the image"
fileName:photoName mimeType:#"image/jpeg"];
} success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(#"Response: %#", responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(#"Error: %#", error);
}];

Please try the below code in AFNetworking 2.0.3
Hope this will helpful for u
- (void) createNewAccount:(NSString *)nickname accountType:(NSInteger)accountType primaryPhoto:(UIImage *)primaryPhoto
{
// Ensure none of the params are nil, otherwise it'll mess up our dictionary
if (!nickname) nickname = #"";
NSLog(#"Creating new account %#", params);
[self POST:#"accounts" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFormData:[nickname dataUsingEncoding:NSUTF8StringEncoding] name:#"nickname"];
[formData appendPartWithFormData:[NSData dataWithBytes:&accountType length:sizeof(accountType)] name:#"type"];
if (self.accessToken)
[formData appendPartWithFormData:[self.accessToken dataUsingEncoding:NSUTF8StringEncoding] name:#"access_token"];
if (primaryPhoto) {
[formData appendPartWithFileData:UIImageJPEGRepresentation(primaryPhoto, 1.0)
name:#"primary_photo"
fileName:#"image.jpg"
mimeType:#"image/jpeg"];
}
} success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(#"Created new account successfully");
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(#"Error: couldn't create new account: %#", error);
}];
}

At last I made it work
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:#"https://blahblahblah.com/uploadProfileImg?userId=1" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData
name:#"key"
fileName:imageName mimeType:extension];
} success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(#"Response: %#", responseObject);
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSHTTPURLResponse *response = (NSHTTPURLResponse *)task.response;
NSLog(#"error: %#",error);
NSLog(#"statusCode: %ld", (long)response.statusCode);
NSString* ErrorResponse = [[NSString alloc] initWithData:(NSData *)error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] encoding:NSUTF8StringEncoding];
NSLog(#"Error Response:%#",ErrorResponse);
}];
