Question

我试图在我的角应用程序中捕获例如500的服务器错误。不幸的是，这种结构失败了：

            return promise = this.httpService.jsonp("serverurl")
            .success((response: any): ng.IPromise<any> => { return response.data; })
            .error((response: any): ng.IPromise<any> => { return response.data; });

我想捕获服务器响应 - 在这种情况下只是消息。怎么做？

$ http服务是一个函数，它接受一个参数 - 一个配置对象 - 用于生成HTTP请求并返回一个promise。

// Simple GET request example:
$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    // this callback will be called asynchronously
    // when the response is available
    console.log(response); // add console log of response
  }, function errorCallback(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
    console.log(response); // add console log of error response
  });

或者拦截器可用于监视＆＃34;所有的http：

// register the interceptor as a service
$provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
  return {
    // optional method
    'request': function(config) {
      // do something on success
      return config;
    },

    // optional method
   'requestError': function(rejection) {
      // do something on error
      if (response.status === 500) {
          //DO WHAT YOU WANT
      }   
      return $q.reject(rejection);
    },



    // optional method
    'response': function(response) {
      // do something on success
      return response;
    },

    // optional method
   'responseError': function(rejection) {
      // do something on error
      if (response.status === 500) {
          //DO WHAT YOU WANT
      }                
      return $q.reject(rejection);
    }
  };
});

$httpProvider.interceptors.push('myHttpInterceptor');
