Question

客户端的站点上载文件，但是如果这些文件很大，则会返回超时错误503 Service Unavailable。

hopedagem将超时时间限制为300秒，是否可以通过js或相关方法以无超时方式进行上传？上传的是视频。

The hosting server does not allow time out editing.

Answer 1

转到php.ini文件并根据您的要求更改值。

upload_max_filesize

默认情况下，此值为2M。我们需要将其增加到要上传的单个文件的最大大小。

max_input_time

这设置允许脚本解析输入数据（如POST和GET）的最长时间（以秒为单位）。计时从在服务器上调用PHP的那一刻开始，到执行开始时结束。这将包括填充$_FILES superglobal。

memory_limit

这设置了PHP脚本在执行期间可以使用的内存量。将此值设置为大于“ post_max_size”的值，以便PHP脚本可以加载和处理上传的文件。

post_max_size

它定义PHP将接受的POST数据的最大大小。此值应大于“ upload_max_filesize”。

max_execution_time

在解析脚本输入后允许其运行的时间。这将包括对文件本身的任何处理。

如果遇到内存相关错误，然后关闭输出缓冲，则要考虑的PHP配置指令为“ output_buffering”

output_buffering = Off

我还添加了以上配置的参考，您可以找到更多详细信息here

Answer 2

您需要在php.ini中更改一些设置：

upload_max_filesize = 500M 
;or whatever size you want

max_execution_time = 1000
; also, higher if you must - sets the maximum time in seconds
