如何獲取Angularjs中的狀態碼？

Question

我們使用AWS和招搖，我們也有GetData方法服務

var getData =() => { 
    return $http({ 
     method: 'GET', 
     url: 'myURL', 
     headers: { 
      'Authorization': 'token' 
     } 
    }); 
}; 

我試圖用波紋管代碼

dataservice.getData().then(response => { 
        console.log(response) 
       }) 
       .catch((err) => { 
        console.log(err)); 
       }) 

有充分請求（使用它時，我autorized ）能正常工作，我得到我的數據，但隨後令牌是無效的，我剛開錯誤whitout控制檯狀態代碼

Object {data: null, status: -1, config: Object, statusText: "", headers: function} 

招搖返回波紋管圖片

我的目標是讓狀態碼401 '不autorized'

我們蘭巴具有波紋結構

exports.handler = (event, context, callback) => { 
    var token = event.authorizationToken; 
    // Call oauth provider, crack jwt token, etc. 
    // In this example, the token is treated as the status for simplicity. 

    switch (token.toLowerCase()) { 
     case 'allow': 
      callback(null, generatePolicy('user', 'Allow', event.methodArn)); 
      break; 
     case 'deny': 
      callback(null, generatePolicy('user', 'Deny', event.methodArn)); 
      break; 
     case 'unauthorized': 
      callback("Unauthorized"); // Return a 401 Unauthorized response 
      break; 
     default: 
      callback("Error: Invalid token"); 
    } 
}; 

我們得到這個從awsdoc

Answer 1

請

.success(function (response) { 
if (response.token){ 

} 
else{ 
// do else case 
} 
}) 

嘗試

Answer 2

在catch()您可以訪問包含status和data的錯誤對象，您可以在其中閱讀有關失敗原因的其他信息。

angular.module('app', []).service('someService', function($http) { 
 
    const getData =() => { 
 
    return $http({ 
 
     method: 'GET', 
 
     url: 'myURL', 
 
     headers: { 
 
     'Authorization': 'token' 
 
     } 
 
    }); 
 
    }; 
 

 
    return { 
 
    getData 
 
    } 
 
}) 
 

 
describe('Some service', function() { 
 

 
    let someService, $httpBackend 
 

 
    beforeEach(module('app')) 
 

 
    beforeEach(inject((_someService_, _$httpBackend_) => { 
 
    someService = _someService_ 
 
    $httpBackend = _$httpBackend_ 
 
    })) 
 

 
    it('returns 401 status',() => { 
 
    const message = {reason: 'some reason'} 
 
    
 
    $httpBackend.whenGET('myURL').respond(401, { message }) 
 

 
    someService.getData().then((response) => { 
 
     expect(response).toBeUndefined() 
 
    }).catch(function(error) { 
 
     expect(error.status).toBe(401) 
 
     expect(error.data.message).toEqual(message) 
 
    }) 
 

 
    $httpBackend.flush() 
 
    }) 
 

 
})
