AFNetworking图片上传

 //上传图片
 -(void)upLoadImage:(UIImage *)upImage
 {
     //创建管理
     AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
     //存放非文件参数
     NSMutableDictionary *params = [NSMutableDictionary dictionary];
     [params setObject:@"qwe" forKey:@"userName"];
     //发送请求
     [manager POST:@"http://192.168.1.27:9000/os/ks/add" parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {

 //        NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
 //        formatter.dateFormat = @"yyyyMMddHHmmss";
 //        NSString *str = [formatter stringFromDate:[NSDate date]];
 //        NSString *fileName = [NSString stringWithFormat:@"%@.jpg", str];

         NSData *fileData = UIImageJPEGRepresentation(upImage, 1.0);

         [formData appendPartWithFileData:fileData name:@"headFile" fileName:self.imageName mimeType:@"image/jpeg"];

     } success:^(AFHTTPRequestOperation *operation, id responseObject) {

         NSLog(@"上传成功");
     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
         NSLog(@"上传失败 ");
     }];

 }

不过需要主要的是：

不要用下面的这个方法来设置文件参数

  [formData appendPartWithFormData:fileData name:self.imageName];

这个方法在上传图片的时候会有问题，用上面的方法就好了；

还有，在发送请求之前要判断方法内参数image是否为nil；
