java - 在Android Studio中从POST获取400的响应代码

为此，我一直在关注Wintech的Youtube教程。我进行了所有设置，并添加了一些额外的POST方法。 GET方法工作正常，但是当我尝试POSTING位时，得到400作为响应代码。我知道这意味着语法不正确/格式错误，但是我找不到那儿。经过数小时的尝试和搜索。是的，我知道我可以在一个类和方法中完成所有操作，我这样做是为了查看引起问题的原因。全部都是。谁能告诉我哪一点可能是错误的？

当我尝试在浏览器中查看它时，我得到java - 在Android Studio中从POST获取400的响应代码-LMLPHP
让我知道我是否提供了足够的信息。

最佳答案

我知道那会很愚蠢。我需要Web服务中的UPDATE sql命令，而不是INSERT。
