javascript - Node.js 出现错误 Nginx 499（客户端关闭连接）

Question

我在网站制作过程中遇到问题。我正在尝试向 Node.js 发送 POST 请求，但它返回错误499。

• nginx
• nodejs（快递包）
• 没有 php

Nginx 配置：

server {
    listen 80;
    listen [::]:80;

    server_name *********.com;

    access_log /var/www/*********/log/access.log main;
    error_log /var/www/*********/log/error.log;

    root /var/www/*********.com/www;
    index index.html;

    if ( $http_x_forwarded_proto != 'https' ) {
            return 301 https://$host$request_uri;
    }

    location / {
            try_files $uri $uri/ =404;
    }

    location /admin/articles {
            proxy_pass http://127.0.0.1:8888/;
    }
}

完整的 Nginx 配置和权限（755 个目录/644 个文件）：

<form method="POST" action="/admin/articles" enctype="multipart/form-data">

    <button id="submit-form" href="" type="submit" class="btn btn-primary btn-form display-4">Ajouter l'article</button>
  </span>
</form>

脚本 Node.js：

app.post('/admin/articles', function(request,response) {
    console.log("Route : app.post /admin/articles");

    var params = {
        pageName        : request.body.pageName,
        pageTitle       : request.body.pageTitle,
        pageDescription : request.body.pageDescription,
        pageDate        : request.body.pageDate,
        pageImg         : request.body.pageImg
    };

    postManager.getLastIndex();
    postManager.writePost(params);

});

访问日志：

"POST /admin/articles HTTP/1.1" 499 0 "https://**********.com/admin/admin.html?pageName=test.html&pageTitle=Module+de+test&pageDescription=dfsdfsdfsf&pageDate=11%2F10%2F1995&pageImg="

我什么都试过了！我不知道错误在哪里。可能是 Nginx 配置的问题。

如果您有想法，请不要犹豫分享！

先感谢您。
