Внутренняя ошибка сервера IOS AFNetworking (500) при загрузке изображения по почте

Question

Вот мой код

-(void)uploadNewImageWithURL:(NSString *)strURL andImage:(UIImage *)image andImageNameWithExtension:(NSString *)strImageName{ 
NSString *path = strURL; 
NSData *imageData = UIImageJPEGRepresentation(image, 0.5); 

NSDictionary *parameters = @{@"booktitle":@"TestUpload", @"author":@"Harry", @"booktype": @"NF", @"message":@"Test for upload1", @"isbn": @"42000004", @"uploadfile":imageData}; 
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/json"]; 
manager.requestSerializer = [AFJSONRequestSerializer serializer]; 
[manager POST:path parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 
    if(image){ 
     [formData appendPartWithFileData:imageData name:@"image" fileName:strImageName mimeType:@"image/jpeg"]; 

    } 
} success:^(AFHTTPRequestOperation *operation, id responseObject) { 
    NSLog(@"success = %@", responseObject); 
} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
    NSLog(@"error = %@", error); 
    NSLog(@"Response = %@", operation); 
}]; 

} 

Вот ответ

Response = <AFHTTPRequestOperation: 0x7fe305931e60, state: isFinished, cancelled: NO request: <NSMutableURLRequest: 0x7fe3058a8f20> { URL: http://www.somewhere.com/api/MakeBook/MakeBookNew/ }, response: <NSHTTPURLResponse: 0x7fe305932c70> { URL: www.somewhere.com/api/MakeBook/MakeBookNew/ } { status code: 500, headers {

Вы можете использовать следующий код для загрузки изображения с помощью AFNetworking.

AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:siteAPIURL]]; 
manager.requestSerializer = [AFHTTPRequestSerializer serializer]; 
manager.responseSerializer = [AFJSONResponseSerializer serializer]; 

if (headers != nil) 
{ 
    NSArray *allHeaders = [headers allKeys]; 

    for (NSString *key in allHeaders) 
    { 
     [manager.requestSerializer setValue:[headers objectForKey:key] forHTTPHeaderField:key]; 
    } 
} 



AFHTTPRequestOperation *op = [manager POST:serviceName parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) 
{ 
    //do not put image inside parameters dictionary as I did, but append it! 
    [formData appendPartWithFileData:imgData name:@"profile_picture" fileName:@"photo.jpg" mimeType:@"image/jpeg"]; 
} success:^(AFHTTPRequestOperation *operation, id responseObject) { 
    NSLog(@"Success: %@ ***** %@", operation.responseString, responseObject); 
    NSLog(@"JSON: %@", responseObject); 

    if (success != nil) 
    { 
     success(operation,responseObject); 
    } 
} failure:^(AFHTTPRequestOperation *operation, NSError *error) { 

    if (failure != nil) 
    { 
     failure(operation,error); 
    } 
}]; 
[op start];
