頁面報如下錯誤

An error occurred.
Sorry, the page you are looking for is currently unavailable.
Please try again later.

If you are the system administrator of this resource then you should check the error log for details.

Faithfully yours, nginx.

其他接口訪問正常
django服務器接收不到請求

解決方案

• 修正方式1：
  uwsgi.ini中加一行配置

buffer-size = 65536

重啟服務后，正常訪問接口

• 修正方式2：
  可將接口修改為POST請求，用請求體傳參
