Question

你好，我通过Ajax Post Request发送大字符串数据，并且在本地主机上工作正常，但是在实时服务器上不工作，我正在发送一些图像数据，然后将此图像数据转换为服务器上的图像。这也花费了很多时间发送此数据的平均数据大小在4到7 MB之间。您还可以建议一种更好的方法以便快速完成吗。也可以进行正确的设置，我包括CSRF令牌，URL也不错，但不知道为什么会发生此错误

Blockquote 您是否仅收到错误500，而没有其他信息？如果是这样，请启用调试，以便您可以更好地描述错误。确保您的php.ini文件设置正确，并且服务器文件夹的权限也合适（我总是会遇到存储文件夹的问题）。
