Reason why post failed to upload large files

Today I found an error when uploading files using post. The reason turned out to be that the file was too large. This is very strange. Isn’t there a size limit for uploading files via post?

The error reported here is not actually a code problem. The error is that the web server has a limit on the file upload size. This will happen when the file size you upload exceeds its limit.

Solution

//如果想修改上传文件的限制可以修改php.ini文件
file_uploads = On;                         //是否允许上传文件 On/off 默认是on
upload_max_filesize = 2048M;               //上传文件最大限制，默认2M
post_max_size = 2048M                      // 通过Post提交的最多数据

max_execution_time = 30000;                //脚本最长的执行事件 单位为秒
max_input_time = 30000；                   //接收提交的数据的时间限制 单位为秒
memory_limit = 2048M;                      //最大内存消耗

The file address on my computer is: H:\wamp\bin\apache\apache2.4.23\bin

Just follow the installation location of your own computer.


Find this file and open it with phpstorm (do not open it with Notepad, there will be format problems)Then Ctrl F to find upload_max_filesize and change it to 2048M (how much you change depends on the individual) (required)

Just change the other ones as well. Use Ctrl S to save all the changes and then restart the web server. Then the test upload is successful.
