我在这个问题上花了 2 周时间。我写了下面的代码(Android 和 php)。似乎还可以，但无法正常工作或无法正常工作。客户端 Android 似乎发送了一些东西服务器端收到了一些东西但我不知道它是什么。

在客户端 Android 和服务器上的代码下方。

谢谢。

最佳答案

这不是一个完整的答案......我将在接下来的过程中完成这个答案......

首先，我建议您检查是否获得了您应该获得的发布数据。请在顶部之后插入:

if (isset($_POST['tag']) && $_POST['tag'] != '') 
{  

...

file_put_contents ("mydebugdata.txt",json_encode($_POST));

这应该将脚本接收到的数据转储到文件“mydebugdata.txt”中...... json_encode() 为 $_POST 提供了一些结构……所以您可以读取数据……

然后尝试保存图片并将 mydebugdata.txt 的内容发布到这里......
