XHR 请求中的 500 内部服务器错误 [英] 500 Internal Server Error on XHR Request

问题描述

这是我的代码:

var fd = new FormData(document.querySelector('#form-step1'));
var xhr = new XMLHttpRequest();

xhr.open('POST', '/Handlers/newAccount_handler.php', true);

xhr.send(fd); // this line is causing a 500 Internal Server Error and the data is not saved to the MySQL table

为什么最后一行会导致 500 Internal Server Error?代码有什么问题吗，还是我需要先登录才能查看?

Why is the last line causing a 500 Internal Server Error? Is there anything wrong with the code or do I need to log anything first to see?

推荐答案

这看起来有点旧，但我也遇到过类似的问题.值得检查您发送的 '#form-step1' 的值.在我的例子中，如果值包含引号，它会抛出一个错误，但使用简单的文本它可以正常工作.

This seems a bit old, but I've had similar issue. It's worth checking what the value of '#form-step1' you are sending. In my case if the value contained quotes it would throw an error, but with simple text it worked fine.
