我有这个脚本，它会产生以下错误：001校验和失败

这是剧本，我不知道它有什么问题，你能帮助我吗？

Answer 1

我不认为这是一个错误。实际上

if($_GET["checksum"] != CHECKSUM) { 
    die (ERR001);
}

这个条件是真的，所以输出没有错误。所以只需从最初得到它的地方检查GET数据。这不是一个程序错误。

你需要通过GET调用脚本，至少使用以下参数：

checksum=739b54dc26

所以，如果您的页面是test.php，则在localhost上以这种方式调用它（当然，您可以在请求字符串中添加其他参数）：

http://localhost/test.php?checksum=739b54dc26

希望有所帮助
