Ant Mobile使用整理

1. fetch 请求java后台接收不到参数解决如下：
   

• 很明显axios请求的Content-Type为application-json，所以后台接收不到
  
  解决：参数使用第三方工具qs.stringify(param) 处理，然后Content-Type设置为 application/x-www-form-urlencoded， 注意，Request Payload 和 Form Data 的区别，主要是参数放的不对导致获取不到

2. React------The “injectBabelPlugin” helper has been deprecated as of v2.0. 报错

使用Antd,会有报错

引入 react-app-rewired 并修改 package.json 里的启动配置。由于新的 [email protected] 版本的关系，你还需要安装 customize-cra，否则会出现如下的问题。

The "injectBabelPlugin" helper has been deprecated as of v2.0. You can use customize-cra plugins in replacement - https://github.com/
arackaf/customize-cra#available-plugins
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] start: `react-app-rewired start`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the [email protected] start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR!     C:\Users\Administrator\AppData\Roaming\npm-cache\_logs\2019-04-25T06_55_17_287Z-debug.log

解决如下：

• 确保安装’customize-cra’并[email protected]
• 确保安装’less’和’less-loader’
• src目录新建 config-overrides.js 文件
  内容如下：

const {
    override,
    fixBabelImports,
    addLessLoader,
  } = require("customize-cra");
  
  
  module.exports = override(
    fixBabelImports("import", {
      libraryName: "antd", libraryDirectory: "es", style: true // change importing css to less
    }),
    addLessLoader({
      javascriptEnabled: true,
      modifyVars: { "@primary-color": "#1DA57A" }
    })
  );

记得关闭项目，重新启动

3. react中配置代理解决跨域问题
   项目中遇到请求跨域问题，我们一般需要项目中配置代理解决。
   我的项目是create-react-app2.0版本生成的。
   首先安装包 http-proxy-middleware

npm install http-proxy-middleware --save
# or
yarn add http-proxy-middleware

然后在src目录下创建 setupProxy.js 文件
最后设置代理

// setupProxy.js
const proxy = require('http-proxy-middleware')

module.exports = function(app) {
  app.use(
    proxy('/api', {  //`api`是需要转发的请求 
      target: 'http://localhost:5000',  // 这里是接口服务器地址
      changeOrigin: true,
    })
  )
}

这里需要注意的是我们的axios的baseURL，设置的时候不能还设置加上原来服务器域名的地址，应该只设置 /api 就好了

axios.defaults.baseURL = '/api';
例如：
axios.post('/v1/register');

发布的时候可以使用nignx转发解决跨域，测试也可以
