在 GAE 中部署时出现 502 Bad Gateway

Question

我正在尝试在 Google App Engine 中部署我的 nodejs 应用程序。但是当我运行

时，我一直收到 502 Bad Gateway

$ gcloud app browse

这是我的文件结构

->project
  |___node_modules
  |___models
  |___routes
  |___index.js
  |___app.yaml
  |___package.json
  |___package.lock.json
  |___public
      |___index.html
      |___js

这是我的 app.yaml 文件

env: flex
runtime: nodejs
threadsafe: true
manual_scaling:
  instances: 1

# Handle the main page by serving the index page.
handlers:
- url: /
  static_files: public/index.html
  upload: public/index.html

- url: /(.*)
  static_files: public/
  upload: public/(.*)

# Recommended file skipping declaration from the GAE tutorials
skip_files:
  - ^(.*/)?app\.yaml
  - ^(.*/)?app\.yml
  - ^(.*/)?#.*#
  - ^(.*/)?.*~
  - ^(.*/)?.*\.py[co]
  - ^(.*/)?.*/RCS/.*
  - ^(.*/)?\..*
  - ^(.*/)?tests$
  - ^(.*/)?test$

  - ^COPYING.LESSER

  - \.gitignore
  - ^\.git/.*
  - \.*\.lint$
  - ^fabfile\.py
  - ^testrunner\.py
  - ^grunt\.js
  - ^node_modules/(.*/)?

注意：我运行宁在端口8080上并且包含"start"："node index.js"在package.json

Answer 1

我发现了我的错误。它在 index.js 文件中。之前：

const port = process.env.PORT || 8080;
app.listen(port, "localhost",()=>{
    console.log("Server running at port " + port);
});

我不得不将其替换为：

const port = process.env.PORT || 8080;
app.listen(port, ()=>{
    console.log("Server running at port " + port);
});
