django中对json的HTTP请求不包含任何内容

Question

求救。

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 json 并请求接收 json。这是我在 android 和 django 中的代码。

但问题是我在 django 中的 request 不包含任何内容。没有标题，没有正文，没有其他内容。当我打印 request.body 时，我只看到 b '' 在原始数据的命令中。

请告诉我哪里错了。

很多。

您的 Java 正在发送到 URL '/post'，但 Django 正在侦听 '/post/'。附加斜杠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。您应该首先发布到“/post/”。
