node.js - 无法加载资源 : the server responded with a status of 405 (Not Allowed) needs help on nginx. conf

标签 node.js reactjs express nginx

我有带 AXIOS 的完整 MERN 堆栈应用程序。在我的本地主机上，该应用程序运行良好，但是当我在 nginx 上部署该应用程序时，所有 POST 请求 都被拒绝。我尝试了很多在网上找到的解决方案，但没有用。我认为这是 CORS 问题/nginx 配置问题。我让 Nginx.conf 正确吗？我的 Node 在 localhost:8000 上运行，React 在 localhost:3000 上运行。

error message 405 not allowed

我尝试过的事情:

Nginx.conf:

server {
    listen 80;

server_name lovechangingtheworld.org;

location / {
    proxy_pass http://localhost:8000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
    }

}

我在 Node 上也需要这个吗？

router.use((request, response, next) => {
  response.header("Access-Control-Allow-Origin", "*");
  response.header(
    "Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE, OPTIONS"
  );
  response.header("Access-Control-Allow-Headers", "Content-Type");
  next();
});

Node :

const router = express.Router();

const bcrypt = require("bcryptjs");
const jwt = require("jsonwebtoken");

  );
  response.header("Access-Control-Allow-Headers", "Content-Type");
  next();
});

最佳答案

你的nginx配置有误。对于要通过 nginx 公开的 Node 应用程序，您需要 Reverse Proxy我已经回答了related question

不使用 SSL 的反向代理的 nginx 配置。 服务器。

server {
    listen 80;

    server_name example.com;

    location / {
        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }

}

使用 SSL

server {

    listen 443;
    server_name example.com;

    ssl_certificate           /etc/letsencrypt/fullchain.pem;
    ssl_certificate_key       /etc/letsencrypt/privkey.pem;

    ssl on;
    ssl_session_cache  builtin:1000  shared:SSL:10m;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    ssl_prefer_server_ciphers on;

    location / {

      proxy_set_header        Host $host;
      proxy_set_header        X-Real-IP $remote_addr;
      proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header        X-Forwarded-Proto $scheme;

      # Fix the “It appears that your reverse proxy set up is broken" error.
      proxy_pass          http://localhost:3000;
      proxy_read_timeout  90s;

      proxy_redirect      http://localhost:3000 https://example.com;
    }
 }

在 example.com 中，您将已注册的域与您的 IP 放在一起。 如果您没有域，可以通过将其添加到主机中来测试它 How to add an IP to hostname file

例子 127.0.0.1 example.com

在你看到 http://localhost:3000; 的地方，你输入了 internal Node 应用程序的 IP 和端口。如果它在同一台机器上，您将其保留为 localhost:port。

在你的情况下

server {
    listen 80;

    server_name lovechangingworld.org;

    location / {
        proxy_pass http://localhost:8000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }

}

要使 nodemailer 工作，有两种方法。假设 nodemailer 在端口 localhost:3000 上运行，要么使用像 lovechangingworld.org:8088< 这样的端口 或创建一个子域，例如 mail.lovechangingworld.org。 在 sites-available 中创建文件 touch mail.lovechangingworld.org 2.添加配置

示例 1 新子域:

server {
        listen 80;

        server_name mail.lovechangingworld.org;

        location / {
            proxy_pass http://localhost:3000;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
        }

    }

示例 2 不同的端口:

 server {
            listen 8088;

            server_name lovechangingworld.org;

            location / {
                proxy_pass http://localhost:3000;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
            }

        }
