Angular uses the Interceptor to uniformly process http requests and responses.

Angular uses the Interceptor to uniformly process http requests and responses.

If you want to use htpp in angularjs to send requests to the backend, a token that is uniquely identified by the user wants to be placed in headers, that is, {headres: {'Token': 1 }}

The following js is introduced in index.html:

angular.module('app.factorys',[])  .factory('httpInterceptor',['$q','$injector','$localStorage',function ($q,$injector,$localStorage) {    var httpInterceptor = {      'responseError' : function(response) {        // ......        return $q.reject(response);      },      'response' : function(response) {        if (response.status == 21000) {          // console.log('do something...');        }        return response || $q.when(response);      },      'request' : function(config) {        config.headers = config.headers || {};        if ($localStorage.token) {          config.headers.token = $localStorage.token;          // config.headers['X-Access-Token'] = $localStorage.token;        };        return config || $q.when(config);        return config;      },      'requestError' : function(config){        // ......        return $q.reject(config);      }    };    return httpInterceptor;  }])

After the factory is injected into the app, configure it in config

.config(['$httpProvider',function(){  $httpProvider.interceptors.push(httpInterceptor);}])

The above angular method of handling http requests and responses with the interceptor is all the content that I have shared with you. I hope you can give us a reference and hope you can provide more support.
