我遇到了以下问题： 注册期间。应用程序将数据发送到服务器，并发送到适当的表，但是在确认注册后。我每次都会收到该错误
有人告诉我为什么会这样吗？=（

这是导入应用程序条目的表的结构。

我认为这是由于在兼捕中确定数据类型时出错。检查过的Java代码和sqlb一切正常，tomuzhe记录都在数据库中创建，这意味着数据类型和php问题不存在，那我的错误是什么？ （

PHP脚本，当输入验证代码时，看起来好像已验证的用户= 1，甚至有一半收到错误«W / System.err：org.json.JSONException：用户无值
$user = $stmt->fetch();

答案 0 :(得分：0)
您正在调用一个不存在的json对象“ user”，它应该是“ app_users_tb”
im = Image.open('filename.webp')
width, height = im.size
print(width,height)
