角JS捕捉服務器錯誤Jsonp

Question

我想在我的角應用程序中捕捉例如500的服務器錯誤。不幸的是，這種構造失敗：

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

我想捕捉服務器響應 - 在這種情況下，只是消息。這個怎麼做？

$ http服務是一個函數，它接受一個參數 - 一個配置對象 - 用於生成一個HTTP請求並返回一個承諾。

// 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 
    }); 

還是一個攔截器可以用來「監視」所有的HTTP的：

// 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');
