Question

我在我的頭用這個來獲取所有數據，我分析我的控制器（的toJSON）標題：

X-Pagination:{"current_page":1,"per_page":10,"total_pages":16,"sub_count":10,"total_count":159} 

var parsingHeader = angular.fromJson(vms.headers('X-Pagination')); 
      _this.current_page = parsingHeader.current_page; 
      _this.per_page = parsingHeader.per_page; 
      _this.total_pages = parsingHeader.total_pages; 
      _this.total_count = parsingHeader.total_count; 

我要測試的這款：

$httpBackend 
     .whenGET('http://localhost:3000/vms.json?page=1') 
     .respond(function(method, url, data, headers){ 
     ... 
     }); 

我有一些錯誤： 'null'不是一個對象（評估'parsingHeader.current_page'），...
什麼是測試這個最好的過程？

您需要將標題X-Pagination:{"current_page":1,"per_page":10,"total_pages":16,"sub_count":10,"total_count":159}傳遞給whenGET。我沒有看到頭傳遞這就是爲什麼parsingHeader變量爲空

做這樣的事情：

$httpBackend 
     .whenGET('http://localhost:3000/vms.json?page=1', ['X-Pagination':{"current_page":1,"per_page":10,"total_pages":16,"sub_count":10,"total_count":159}]) 
     .respond(function(method, url, data, headers){ 
     ... 
     });
