Question

有没有办法改变nginx发送的响应代码？当服务器收到超过配置中定义的client_max_body_size的文件时，我可以让它返回403代码而不是413代码吗？

Answer 1

以下对我来说很好

events {
    worker_connections  1024;
}
http {
server {
   listen 80;

    location @change_upload_error {
       return 403 "File uploaded too large";
    }

    location /post {
       client_max_body_size 10K;
       error_page 413 = @change_upload_error;
       echo "you reached here";
    }
}

}

发布50KB文件的结果

$ curl -vX POST -F file=@test.txt vm/post
Note: Unnecessary use of -X or --request, POST is already inferred.

和nginx日志

web_1       | 2017/09/11 17:58:55 [error] 5#5: *1 client intended to send too large body: 51337 bytes, client: 192.168.33.1, server: , request: "POST /post HTTP/1.1", host: "vm"

从413更改nginx响应代码
