我有一个 android 应用程序，用户从 gallery 中选择一个 image，然后当他保存它时，image 保存在我的 server 上的 UPLOADS 文件夹中，在 MySQL 表中，图像 url 是已保存。
我使用 retrofit 来保存照片。
我有一个问题，当用户选择 photo 并保存它时，应用返回错误 End of input at line 1 column 1 path $，但照片完美保存在服务器上，URL 保存在 MySQL 上。
但我应该收到 Toast 消息，而不是在第 1 行第 1 列路径 $ 处收到 End of input error。
我怎样才能停止收到该错误消息？

最佳答案
当您的响应完全为空时会发生此错误。所以检查你必须检查 php 文件
正如我所见，您永远不会返回或打印输出以从 android 接收它。
在php文件末尾添加这一行
echo json_encode($output);
关于php - 使用 Android 应用程序使用 URL 在服务器上保存图像 ERROR 输入错误结束在第 1 行第 1 列路径 $，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56617774/
