angualrjs 配置超时时间

Posted 2020-10-29 知行合一

timeout 1

---

本想通过$httpProvider的defaults属性配置timeout时间, defaults中没有这个属性. https://docs.angularjs.org/api/ng/provider/$httpProvider#defaults

timeout 2

---

在拦截器中为request的config配置timeout, 在response中根据xhrStatus=timeout来处理超时. 奈何response中没找到这个xhrStatus 

官网里说status=-1表示请求被取消, timeout时就会取消请求, 那就用这个来判断吧
https://docs.angularjs.org/api/ng/service/$http#$http-returns

``` (function() {

angular.module("mobile")

.factory(\'HttpInterceptor\', [\'$q\',
  function($q) {
    return {
      request: function(config) {
        // 设置超时时间, 毫秒
        config.timeout = 1;

        if (config.url.search("service/") < 0)
          return config;
        if (localStorage.getItem(\'token\')) {
          config.params = config.params || {};
          config.params[\'token\'] = localStorage.getItem(\'token\');
          config.params[\'t\'] = new Date().getTime();
        }
        return config;
      },
      requestError: function(err) {
        return $q.reject(err);
      },
      response: function(res) {
        console.log(\'res: \',res);

        if(res.statusText==\'timeout\')
        {
          console.log(\'timeout: \',111);

          alert(\'请求超时\');

          // 处理各类自定义错误
        } else if (501 === err.status) {
