我试过用邮递员。所以它工作得很好：所以我认为没有服务器错误

您作为字符串发送的json正文，尝试将其作为json对象发送。服务器可能需要一个json对象。否则，标题值可能会出现问题。在“邮递员”中检查您从那里发送的邮件头是否与从应用程序发送的邮件头相同。

您有一个服务器错误（即在应用程序之外）。您需要检查服务器日志以查找错误的根本原因，然后从那里开始。如果您希望在Android上处理此错误，则需要检查服务器返回的状态。@Christillwell我已在服务器上添加了server logI Im Get empty body，因此这可能是来自appHTTP.500的错误。您的服务器提供了一个响应代码，而不是截击生成的内容。看起来您的服务器遇到了空值。您是否正在向服务器发送它所需的所有值？我还将发送jsonObject。这就是打字错误。我和邮递员商量过了，用同样的信物也行。
