The error says it all: you got a 400 responsefrom the server, meaning that what you sent was either not formatted properly, or the server just couldn't understand it.
错误说明了一切：您收到了来自服务器的400 响应，这意味着您发送的内容要么格式不正确，要么服务器无法理解。

I had experienced the same issue. In my case its only for upload Image with larger size. Our server has limited with max.upload size. I resized the image and uploaded, and the issue is gone.
我遇到过同样的问题。在我的情况下，它仅用于上传更大尺寸的图像。我们的服务器限制了 max.upload 大小。我调整了图像大小并上传，问题消失了。
You can resize the image with:
您可以使用以下方法调整图像大小：
+ (UIImage*)imageWithImage:(UIImage*)image
scaledToSize:(CGSize)newSize;
{
UIGraphicsBeginImageContext( newSize );
[image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
