推荐答案

检查URL确实是一个形象，而不是一个HTML文件。有这个令人沮丧的问题，然后我意识到我曾试图下载一个位图在一个WiFi热点......这要求我先登陆。你保存的图像可能显示，当您需要登录！HTML文件

Check that the URL is indeed an image, and not a HTML file. Had this frustrating issue and then I realized I had attempted to download a bitmap over a WiFi hotspot... which required me to log in first. Your saved image is probably the HTML file that shows when you need to log in!

在保存前，检查前几个字节，以确保它是一个PNG，XML，JPG，等等。

Before saving it, check the first few bytes to make sure it is a PNG, XML, JPG, whatever.
