我想在Heroku上部署我的Expree.js“博客-网站”项目，但是在多次尝试soo之后，我得到了“应用程序错误”，您的应用程序已经崩溃了"H10“。这是package.json文件。我跟随了所有的步骤，如果我错过了什么，请告诉我：

代码语言：javascript
复制
{
  "name": "ejs-challenge",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "node app.js"
 },
  "repository": {
    "type": "git",
    "url": "git@github.com:soniiya/Blogging-final.git"
  },
  "author": "",
  "license": "ISC",
  "engines": {
    "node": "14.17.6"
  },

并在我的app.js文件中添加了以下内容：

代码语言：javascript
复制
app.listen(process.env.PORT || 3000, function () {
  console.log("Server started on port 3000");
});

我也创建了Procfile "web: node app.js“。实际上，当我在没有用户身份验证功能的情况下部署同一个应用程序时，它成功地部署了，但是当添加身份验证时，它现在崩溃了。我用MongoDB做数据库，如果你有什么建议，请告诉我。什么能导致“应用程序崩溃”在heroku上？

1.尝试设置这种类型的目录结构

代码语言：javascript
复制
|__client/  THIS IS EVERYTHING FROM THE REACT SIDE 
    |__ node_modules/
        |__ tons of stuff...
    |__ public/
        |__ index.html
        |__ favicon.ico
        |__ etc.
    |__ src/
        |__ index.js
        |__ main/
            |__ App.js
            |__ etc.
|__ models/
    |__ user.js
    |__ todo.js
    |__ etc.
|__ node_modules/
    |__ stuff...
|__ routes
    |__ userRoutes.js
    |__ todoRoutes.js
    |__ etc.
|__ .gitignore
|__ package.json
|__ server.js
|__ etc.

2.请添加此中间件

代码语言：javascript
复制
// ... Other imports
const path = require("path");

// Other app.use middleware
app.use(express.static(path.join(__dirname, "client", "build")));

// Right before your app.listen(), add this:
app.get("*", (req, res) => {
  res.sendFile(path.join(__dirname, "client", "build", "index.html"));
});

app.listen(...);

package.json 3.基于部署服务器向客户端的添加代理

代码语言：javascript
复制
"proxy": "http://localhost:8000"

所以，你的package.json文件看起来.

代码语言：javascript
复制
{
    "name": "client",
    "version": "0.1.0",
    "private": true,
    "dependencies": {
        "axios": "^0.17.1",
        "react": "^16.2.0",
        "react-dom": "^16.2.0",
        "react-scripts": "1.0.17"
    },
    "scripts": {
        "start": "react-scripts start",
        "build": "react-scripts build",
        "test": "react-scripts test --env=jsdom",
        "eject": "react-scripts eject"
    },
    "proxy": "http://localhost:8000"
}

4.在网站上设置环境变量：

代码语言：javascript
复制
A. Open your app in Heroku
B. Go to "Settings"
C. Click "Reveal Config Vars"
D. Add a new variable and click "Add". Done!
E. Your port has to look like:- process.env.PORT || 8000

你的港口看起来是这样的

代码语言：javascript
复制
const port = process.env.PORT || 8000;
.
.
.
app.listen(port);

5.设置MongoDB Atlas IP访问控制

接下来，您需要白名单您的IP地址，以便您可以访问您的集群。转到导航菜单上的网络访问，并添加IP地址。您可以添加当前IP地址，也可以添加允许从任何地方访问。确认了你的选择。

对于通过Heroku部署的任何项目，您必须从任何地方选择“允许访问”。这是因为Heroku使用动态IP。虽然这不是最安全的选择，但目前还可以。

添加此脚本( start heroku-postbuild 和 engines )

在所有这些之后，您的服务器的package.json应该如下所示:在终端中键入node -v。它应该会说出您正在使用的Node.js版本。在"engines": "14.17.5"中添加此版本

代码语言：javascript
复制
{
    "name": "mern-to-heroku",
    "version": "1.0.0",
    "main": "server.js",
    "license": "MIT",
    "dependencies": {
        "body-parser": "^1.18.2",
        "express": "^4.16.2",
        "mongoose": "^4.13.6",
        "morgan": "^1.9.0"
    },
    "scripts": {
        "start": "node server.js",
        "heroku-postbuild": "cd client && npm install --only=dev && npm install && npm run build"
    },
    "engines": {
        "node": "14.17.5"
    }
}

现在，您应该准备好通过Heroku部署您的站点！

问题是你的应用程序找不到谷歌客户端ID。

在Heroku中，您似乎没有正确地配置.env变量。解决办法真的很简单。

DOTENV方法如果您已经以这种方式定义了您的.env，

代码语言：javascript
复制
MONGO_URL="xxx.....xxx"
GOOGLE_CLIENT_ID="xx......xxx"
GOOGLE_CLIENT_SECRET="xxx.....xxx"

在你的护照设置和数据库设置中，

代码语言：javascript
复制
require('dotenv').config();
.
.
.
passport.use(
  new GoogleStrategy
  (
    {
      clientID : process.env.GOOGLE_CLIENT_ID,
      clientSecret : process.env.GOOGLE_CLIENT_SECRET,
      callbackURL : '/auth/google/callback'
    },
.
.
.

然后，您必须在计算机上的项目根目录中声明了一个.env文件。

您的.gitignore文件可能会提到.env，因为这是标准的方法(不将env变量推送到公共/团队存储库)。

它在您的计算机上工作的原因是，应用程序具有环境变量的上下文。在Heroku中，由于.env文件不存在，应用程序不知道在哪里可以找到它们。

您所要做的就是向Heroku添加环境变量。只需转到Heroku仪表板中的设置，转到Config变量菜单。

以格式添加env变量

重启迪诺号。

这会解决你的问题。

app.js 1.在中添加此中间件

代码语言：javascript
复制
  app.use(express.static(path.join(__dirname, "public")));

2.文件夹结构

代码语言：javascript
复制
|__public/   
    |__ css/
        |__ css files...
    |__ js/
        |__ js files...

3.以这种方式导入

现在，将路径设置为公共目录，在导入时必须给出路径公用文件夹。

代码语言：javascript
复制
<link rel="stylesheet" href="/css/main.css" />

<script src="/js/main.js" crossorigin="anonymous"> </script>

现在您应该全部设置为访问CSS文件。
