上传图片到服务器

上传单张图片
//上传图片(单张)

+(void)uploadPhotoAndController:(UIViewController *)controller WithSize:
(CGSize)size Image:(UIImage*)image AndFinish:(void (^)(NSDictionary *, NSError *))finish 
{
//加载提示菊花
MBProgressHUD *hud;

    hud = [MBProgressHUD showHUDAddedTo:controller.view animated:YES];
    hud.label.text = NSLocalizedString(@"加载中...", @"HUD loading title");
                  }

//1. 存放图片的服务器地址，这里我用的宏定义
NSString * url = [NSString stringWithFormat:@"%@%@",Hx_Main_heard_API,IMAGE_UPLOAD_URL_API];

//2. 利用时间戳当做图片名字
   NSDateFormatter *formatter = [[NSDateFormatter alloc] init];  
formatter.dateFormat = @"yyyyMMddHHmmss";  
NSString *imageName = [formatter stringFromDate:[NSDate date]];  
NSString *fileName = [NSString stringWithFormat:@"%@.jpg",imageName];

//3. 图片二进制文件
NSData *imageData = UIImageJPEGRepresentation(image, 0.7f);
NSLog(@"upload image size: %ld k", (long)(imageData.length / 1024));

//4. 发起网络请求

manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager POST:url parameters:nil constructingBodyWithBlock:^(id formData) {
    // 上传图片，以文件流的格式，这里注意：name是指服务器端的文件夹名字,
   //参数fileName可以是任意以.jpg/.jpeg/.png/.gif结尾的字符串,
  //参数mimeType可以是@"image.jpg/@"image.jpeg"/@"image.png"/@" image.gif"中的任意一个
    [formData appendPartWithFileData:imageData name:@"file" fileName:fileName mimeType:@"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
    //上传成功时的回调
    [hud hideAnimated:YES];
    NSLog(@"%@",responseObject);
