This article mainly describes the timeout items in $ HTTP (config) config:

$http({   timeout: number})

Value. It is calculated from the time the request is sent. The number of milliseconds has elapsed. If no response is received, an error is returned.

Demo:

HTML:

<!DOCTYPE html>

JS:


var jsonData = {name:"code_bunny"};var httpGet = angular.module(‘HttpGet‘,[]);httpGet.factory(‘getData‘,function($http,$q){    return function(){        var defer = $q.defer();        $http({            method:‘post‘,            url:‘/api/user‘,            data: jsonData,            headers: {‘Authorization‘:‘code_bunny‘},            timeout: 1000        }).success(function(data,status,headers,config){            defer.resolve(data);        }).error(function(data,status,headers,config){            defer.reject(data)        });        return defer.promise    }});httpGet.controller(‘dataController‘,function($scope,getData){    $scope.data = getData()});


Nodejs:


var express = require(‘express‘);var bodyParser = require(‘body-parser‘);var app = express();// parse application/x-www-form-urlencodedapp.use(bodyParser.urlencoded({ extended: false }));// parse application/jsonapp.use(bodyParser.json());app.use(express.static(__dirname+‘‘));var data = "name=code_bunny&age=3";app.post(‘/api/user‘,function(req,res){    console.log(req.body);    setTimeout(function(){        res.send(data)    },2000)});app.listen(3000);


As shown in the code, we set the content to be returned after 2000 milliseconds in the background, but set the wait time to 1000 milliseconds in $ HTTP congif. Therefore, the data is not returned in the background, the request will be canceled:




 


* Note: timeout can only be configured in a single $ HTTP (). It cannot be configured through $ httpprovider. defaults. Timeout.
