Take a look at https://en.wikipedia.org/wiki/List_of_HTTP_status_codes看看https://en.wikipedia.org/wiki/List_of_HTTP_status_codes
A 502 error indicates a problem with the server you're trying to upload to, and in particular, with one of its upstream servers. 502 错误表示您尝试上传到的服务器存在问题，特别是其上游服务器之一。 If you're not getting this error on other clients trying to upload to the same URL (eg, a web browser), in my experience the culprit is the gateway server and upstream server not dealing with headers the same way, but your mileage may vary.如果您在尝试上传到相同 URL（例如 Web 浏览器）的其他客户端上没有收到此错误，根据我的经验，罪魁祸首是网关服务器和上游服务器没有以相同的方式处理标头，但您的里程可能会增加各不相同。
