This article mainly introduces about react request.js function encapsulation, which has certain reference value. Now I share it with everyone. Friends in need can refer to it
1.request.js function encapsulation
import { Toast } from 'antd-mobile'; import axios from 'axios'; import store from '../store'; import { push } from 'react-router-redux'; import qs from 'qs'; // 请求路径 const BaseUrl = 'https://www.baidu.com/'; // 主机及端口 //axios默认配置请求的api基础地址 axios.defaults.baseURL = BaseUrl; // axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded'; // post 内容类型 // axios.defaults.headers.get['Content-Type'] = 'application/json;charset=utf-8'; // get 内容类型 // axios.defaults.headers.post['Content-Type'] = 'multipart/form-data'; // post 内容类型 formData 类型 axios.defaults.timeout = 30000; // 超时设置,超时进入错误回调,进行相关操作 axios.defaults.withCredentials = false; // 是否支持跨域cookie const codeMessage = { 200: '服务器成功返回请求的数据', 201: '新建或修改数据成功。', 202: '一个请求已经进入后台排队(异步任务)', 204: '删除数据成功。', 400: '发出的请求有错误,服务器没有进行新建或修改数据,的操作。', 401: '用户没有权限(令牌、用户名、密码错误)。', 403: '用户得到授权,但是访问是被禁止的。', 404: '发出的请求针对的是不存在的记录,服务器没有进行操作', 406: '请求的格式不可得。', 410: '请求的资源被永久删除,且不会再得到的。', 422: '当创建一个对象时,发生一个验证错误。', 500: '服务器发生错误,请检查服务器', 502: '网关错误', 503: '服务不可用,服务器暂时过载或维护', 504: '网关超时', }; function checkStatus(response) { if (response.status >= 200 && response.status < 300) { return response; } const errortext = codeMessage[response.status] || response.statusText; // 提示框 Toast.info(`请求错误 ${response.status}: ${response.url}`,1) const error = new Error(errortext); error.name = response.status; error.response = response; throw error; } /** * Requests a URL, returning a promise. * * @param {string} url The URL we want to request * @param {object} [options] The options we want to pass to "fetch" * @return {object} An object containing either "data" or "err" */ export default function request(url, options) { const defaultOptions = { credentials: 'include', }; const newOptions = { ...defaultOptions, ...options }; if ( newOptions.method === 'POST' || newOptions.method === 'PUT' || newOptions.method === 'DELETE' ) { if (!(newOptions.body instanceof FormData)) { newOptions.headers = { Accept: 'application/json', 'Content-Type': 'application/x-www-form-urlencoded', ...newOptions.headers, }; newOptions.data = qs.stringify(newOptions.body); newOptions.body = JSON.stringify(newOptions.body); } else { // newOptions.body is FormData newOptions.headers = { Accept: 'application/json', ...newOptions.headers, }; } } return axios(url, newOptions) .then(checkStatus) .then((response) => { // 成功的回调 if (newOptions.method === 'DELETE' || response.status === 204) { return response.text(); } return response.data; }) .catch((e) => { // 失败的回调 const { dispatch } = store; const status = e.name; if (status === 401) { dispatch({ type: 'login/logout', }); return; } if (status === 403) { dispatch(push('/exception/403')); return; } if (status <= 504 && status >= 500) { dispatch(push('/exception/500')); return; } if (status >= 404 && status < 422) { dispatch(push('/exception/404')); } }); }
2.Note: The method of passing an array to the background
needs to set itsindicestofalse## in the qs method # can be used, such as:
qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });
