Question

SOS。

我真的厌倦了寻找我的简单问题。请帮帮我。

我有一个Android应用程序，它与我的django服务器建立HTTP连接并发送一个json并请求json接收。我的代码在android和django中。

但问题是我的请求在django中不包含任何内容。没有标题，没有正文，也没有其他内容。当我打印 request.body 时，我看到的只是b ''在原始数据的命令中。

请告诉我哪里出错了。

Answer 1

您的Java正在发送到网址＆＃39; / post＆＃39;，但Django正在收听＆＃39; / post /＆＃39;。附加斜线中间件将从第一个重定向到第二个，但重定向始终是GET，因此正文将丢失。你应该发布到＆＃39; / post /＆＃39;首先。

django中json的HTTP请求不包含任何内容
