axios据请求

axios封装:基本不用封装,只是对请求的接口地址,超时,报错处理

  • 安装axios
    npm i axios -S
    axios官方github仓库地址:https://github.com/axios/axios
  • 简洁语法:
//get语法语法
axios.get('/user', {
    params: {
      ID: 12345
    }
  })
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  })
//post请求语法
axios.post('/user', {
    firstName: 'Fred',
    lastName: 'Flintstone'
  })
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });
function getUserAccount() {
  return axios.get('/user/12345');
}

function getUserPermissions() {
  return axios.get('/user/12345/permissions');
}

//可以用axios同时请求多个接口,类似于Promise.all()
axios.all([getUserAccount(), getUserPermissions()])
  .then(axios.spread(function (acct, perms) {
    // Both requests are now complete
  }));
  • axios通过配置对象来请求数据
//post请求
axios({
  url:'接口地址',
  baseURL:‘接口默认前缀地址’
  method:'post',
 // data:{  }, //传参,注意:post请求有可能会用qs库去转换
  data:qs.stringify(obj)
  headers:{'content-tpye':'application/x-www-form-urlencoded',......}, //请求头配置
  
});

例如:

import qs from 'qs';
const data = { 'bar': 123 };
const options = {
  method: 'POST',
  headers: { 'content-type': 'application/x-www-form-urlencoded' },
  data: qs.stringify(data),
  url,
};
axios(options);

//get请求
axios({
  url:'接口地址',
  method:'get',
  params:{  }, //传参
  headers:{'content-tpye':'x-www-form-urlencoded',......}, //请求头配置
  
});
  • axios的默认配置
axios.defaults.baseURL = '默认接口域名url';
axios.defaults.headers['x-token'] = token值;  //添加token
axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
  • 创建axios实例
const instance = axios.create({
  baseURL: '默认接口域名url',
  timeout:2500
});

//instance.defaults.timeout = 2500;  //给实例添加默认超时时间
  • axios拦截器
// 添加请求拦截
axios.interceptors.request.use(function (config) {
    //发送成功请求
    config.headers['x-token']=getToken()
    return config;
  }, function (error) {
    //发送错误请求的拦截
    return Promise.reject(error);
  });

// 添加响应拦截
axios.interceptors.response.use(function (res) {
    //成功返回
    if(res.code===2000) {
      
    }
    
    if(res.code===5000) {
      Tosst({
        title:'登录超时'
      })
      
      router.push({
      path:'/login'
      })
    }
    return res;
  }, function (error) {
    //失败返回
    return Promise.reject(error);
  });
