Question

我正在制作练习网络服务（客户端的艺术书显示网站）客户端可以将艺术图像上传到服务器。

但是当客户端上传过多图片时，我收到以下错误

@Override
protected void onMain_ButtonSubirAPIAction(Component c, ActionEvent event) {
    String picture = Capture.capturePhoto(width, -1);
    if(picture!=null){
        String cloudinaryURL = "https://api.cloudinary.com/v1_1/"+CLOUDNAME+"/image/upload";
        MultipartRequest request = new MultipartRequest() {
           protected void readResponse(InputStream input) throws IOException  {
              JSONParser jp = new JSONParser();
              Map <String, Object> result = jp.parseJSON(new InputStreamReader(input, "UTF-8"));
              labelX.setText((String)result.get("url"));
           }
        };

        request.setPost(true);
        request.setHttpMethod("POST");
        String encoded = Base64.encodeNoNewline((APIKEY + ":" + APISECRET).getBytes());
        request.addRequestHeader("Authorization", "Basic " + encoded);
        request.setUrl(cloudinaryURL);
        try {
            request.addData("file", picture, "image/jpeg");
            request.addArgument("public_id", "name1");
            NetworkManager.getInstance().addToQueue(request);
        } catch(Exception err) {
        }
    }
}

我尝试在nginx.conf中添加413 Request Entity Too Large

client_max_body_size 100M;

并尝试：

#user  nobody;
#Defines which Linux system user will own and run the Nginx server

worker_processes  1;

#error_log  logs/error.log; #error_log  logs/error.log  notice;
#Specifies the file where server logs.

#pid        logs/nginx.pid;
#nginx will write its master process ID(PID).

events {
    worker_connections  1024;
}


http {
    include       mime.types;

    default_type  application/octet-stream;

    #access_log  logs/access.log  main;

    sendfile        on;

    server {
        listen       80;

        server_name  xxxx.net;
        client_max_body_size 100M;
        keepalive_timeout 5;

        return 301 https://$server_name$request_uri;

    }

    # HTTPS server
    #
    server {
        listen       443 default_server ssl;
        server_name  xxx.net;

        ssl_certificate      /etc/letsencrypt/live/xxxx.net/fullchain.pem;
        ssl_certificate_key  /etc/letsencrypt/live/xxxx.net/privkey.pem;

        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;


        location / {
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto https;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header HOST $http_host;
            proxy_set_header X-NginX-Proxy true;

            proxy_pass http://127.0.0.1:8000;
            proxy_redirect off;
        }
    }
}

并重试

sudo service nginx restart
sudo service nginx reload

但仍然得到

runserver

有人可以帮忙吗？

您已解决HTTP服务器上的问题，但是HTTP服务器设置为301重定向到HTTPS服务器...您的HTTPS服务器未配置client_max_body_size，因此默认为1M＆导致此 413（请求实体太大）错误。

要解决此问题，您只需将client_max_body_size添加到两者 HTTP服务器块和，如下例所示：

http {
    ...
    ######################
    # HTTP server
    ######################
    server {
        ...
        listen       80;
        server_name  xxxx.net;
        client_max_body_size 100M;
        ...
    }

    ######################
    # HTTPS server
    ######################
    server {
        ...
        listen       443 default_server ssl;
        server_name  xxxx.net;
        client_max_body_size 100M;
        ...
    }
}

有关client_max_body_size的更多信息，请访问：http://nginx.org/en/docs/http/ngx_http_core_module.html#client_max_body_size

语法：client_max_body_size大小；

默认值：client_max_body_size 1m;

上下文：http，服务器，位置

设置客户端请求正文的最大允许大小，在   “内容长度”请求标头字段。如果在请求中的大小   超过配置的值，则出现413（请求实体太大）错误   返回给客户端。请注意，浏览器无法   正确显示此错误。将大小设置为0将禁用对   客户请求正文大小。
