mocker-api

mocker-api 为 REST API 创建模拟。 当您尝试在没有实际 REST API 服务器的情况下测试应用程序时，这将很有帮助。

特点:

🔥 内置对 Mocker 文件热更新支持。 🚀 通过JSON快速轻松地配置API。 🌱 模拟API代理变得简单。 💥 可以独立使用，而无需依赖 webpack 和 webpack-dev-server。

快速开始

mkdir mocker-app && cd mocker-app

# 根据规则创建模拟程序配置文件
touch api.js

# 全局安装。
npm install mocker-api -g
# 运行服务
mocker ./api.js

# Run server at localhost:8000
mocker ./api.js --host localhost --port 8000

安装

您可以将其 package.json 配置作为当前项目依赖项。

npm install mocker-api --save-dev

使用

mocker-api 支持模拟，在 mocker / index.js 中配置。

您可以修改 http-proxy 选项并通过添加 httpProxy 配置来添加事件监听器

const proxy = {
  // 优先处理。
  // apiMocker(app, path, option)
  // 这是 apiMocker 的选项参数设置 `option`
  _proxy: {
    proxy: {
      // 将路径字符串（例如`/user/:name`）转换为正则表达式。
      // https://www.npmjs.com/package/path-to-regexp
      '/repos/(.*)': 'https://api.github.com/',
      '/:owner/:repo/raw/:ref/(.*)': 'http://127.0.0.1:2018',
      '/api/repos/(.*)': 'http://127.0.0.1:3721/'
    },
    // 重写目标网址路径。对象键将用作RegEx来匹配路径。
    // https://github.com/jaywcjlove/mocker-api/issues/62
    pathRewrite: {
      '^/api/repos/': '/repos/',
    },
    changeHost: true,
    // 修改 http-proxy 选项
    httpProxy: {
      options: {
        ignorePath: true,
      },
      listeners: {
        proxyReq: function (proxyReq, req, res, options) {
          console.log('proxyReq');
        },
      },
    },    
  },
  // =====================
  // 默认的 GET 请求。
  // https://github.com/jaywcjlove/mocker-api/pull/63
  '/api/user': {
    id: 1,
    username: 'kenny',
    sex: 6
  },
  'GET /api/user': {
    id: 1,
    username: 'kenny',
    sex: 6
  },
  'GET /api/user/list': [
    {

      sex: 6
    }, {
      id: 2,
      username: 'kenny',
      sex: 6
    }
  ],
  'GET /api/:owner/:repo/raw/:ref/(.*)': (req, res) => {
    const { owner, repo, ref } = req.params;
    // http://localhost:8081/api/admin/webpack-mock-api/raw/master/add/ddd.md
    // owner => admin

    return res.json({
      id: 1,
      owner, repo, ref,
      path: req.params[0]
    });
  },
  'POST /api/login/account': (req, res) => {
    const { password, username } = req.body;
    if (password === '888888' && username === 'admin') {
      return res.json({
        status: 'ok',
        code: 0,
        token: "sdfsdfsdfdsf",
        data: {
          id: 1,

    } else {
      return res.status(403).json({

    }
  },
  'DELETE /api/user/:id': (req, res) => {
    console.log('---->', req.body)
    console.log('---->', req.params.id)
    res.send({ status: 'ok', message: '删除成功！' });
  }
}
module.exports = proxy;

参数设置

• proxy => {} Proxy settings, Turn a path string such as /user/:name into a regular expression.
• pathRewrite => {} rewrite target's url path. Object-keys will be used as RegExp to match paths. #62
• withFullUrlPath=false => Boolean the proxy regular expression support full url path. if the proxy regular expression like /test?a=1&b=1 can be matched. #25
• priority => proxy priority proxy or mocker #151
• changeHost => Boolean Setting req headers host.
• httpProxy => {} Set the listen event and configuration of http-proxy
• bodyParserJSON JSON body parser
• bodyParserText Text body parser
• bodyParserRaw Raw body parser
• bodyParserUrlencoded URL-encoded form body parser
• bodyParserConf => {} bodyParser settings. eg： bodyParserConf : {'text/plain': 'text','text/html': 'text'} will parsed Content-Type='text/plain' and Content-Type='text/html' with bodyParser.text
• watchOptions => object Options object as defined chokidar api options
• header => {} Access Control Allow options.

  {
    header: {
      'Access-Control-Allow-Methods': 'POST, GET, OPTIONS, PUT, DELETE',
    }
  }
  

⚠️ No wildcard asterisk * - use parameters instead (.*), support v1.7.3+

延迟响应

您可以使用功能性工具来增强模拟效果。#17

const delay = require('mocker-api/delay');
const noProxy = process.env.NO_PROXY === 'true';

const proxy = {
  'GET /api/user': {
    id: 1,
    username: 'kenny',
    sex: 6
  },
  // ...
}
module.exports = (noProxy ? {} : delay(proxy, 1000));

apiMocker

apiMocker(app, mockerFilePath[, options])
apiMocker(app, Mocker[, options])

多个模拟文件监听

const apiMocker = require('mocker-api');
const mockerFile = ['./mock/index.js'];
// or
// const mockerFile = './mock/index.js';
apiMocker(app, mockerFile, options)

实例

在命令行中使用

Base example

⚠️ Not dependent on webpack and webpack-dev-server.

# Global install dependent.
npm install mocker-api -g
# Run server
mocker ./mocker/index.js

Or you can put it the package.json config as a current project dependency.

{
  "name": "base-example",
  "scripts": {
+    "api": "mocker ./mocker"
  },
  "devDependencies": {
+    "mocker-api": "2.9.5"
  },
  "license": "MIT"
}

在 Express 中使用

Express example

⚠️ Not dependent on webpack and webpack-dev-server.

const express = require('express');
+ const path = require('path');
+ const apiMocker = require('mocker-api');

const app = express();

+ apiMocker(app, path.resolve('./mocker/index.js'))
app.listen(8080);

or

const express = require('express');
+ const apiMocker = require('mocker-api');

const app = express();

+ apiMocker(app, {
+   'GET /api/user': {
+     id: 1,
+     sex: 0
+   }
+ });

app.listen(8080);

在 Webpack 中使用

webpack example

To use api mocker on your Webpack projects, simply add a setup options to your webpack-dev-server options:

Change your config file to tell the dev server where to look for files: webpack.config.js.

const HtmlWebpackPlugin = require('html-webpack-plugin');
+ const path = require('path');
+ const apiMocker = require('mocker-api');

module.exports = {
  entry: {
    app: './src/index.js',
  },
  output: {
    filename: '[name].bundle.js',
    path: path.resolve(__dirname, 'dist')
  },
+ devServer: {
+   ...
+   before(app){
+     apiMocker(app, path.resolve('./mocker/index.js'), {
+       proxy: {
+         '/repos/*': 'https://api.github.com/',
+         '/:owner/:repo/raw/:ref/*': 'http://127.0.0.1:2018'
+       },
+       changeHost: true,
+     })
+   }
+ },
  plugins: [
    new HtmlWebpackPlugin({
      template: path.resolve('./public/index.html'),
      title: 'Webpack App Mocker API'
    })
  ],
};

Must have a file suffix! For example: ./mocker/index.js.

Let's add a script to easily run the dev server as well: package.json

{
  "name": "development",
  "version": "1.0.0",
  "description": "",
  "main": "webpack.config.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
+    "start": "webpack serve --progress --mode development",
    "build": "webpack --mode production"
  },
  "keywords": [],
  "author": "",
  "license": "MIT",
  "devDependencies": {
    "html-webpack-plugin": "4.5.0",
    "mocker-api": "2.9.5",
    "webpack": "5.22.0",
    "webpack-cli": "4.5.0",
    "webpack-dev-server": "3.11.2"
  }
}

Mock API proxying made simple.

{
  before(app){
+   apiMocker(app, path.resolve('./mocker/index.js'), {
+     proxy: {
+       '/repos/*': 'https://api.github.com/',
+     },
+     changeHost: true,
+   })
  }
}

在 create-react-app 中使用

create-react-app example

创建 src/setupProxy.js 并放置以下内容：

+ const apiMocker = require('mocker-api');
+ const path = require('path');

module.exports = function(app) {
+  apiMocker(app, path.resolve('./mocker/index.js'), {
+    proxy: {
+      '/repos/(.*)': 'https://api.github.com/',
+    },
+    changeHost: true,
+  });
};

{
  .....
  "devDependencies": {
+    "mocker-api": "2.9.5"
  },
  ....
}
