Angular2 http Nativescript和angular 2应用程序在进行http调用时中断

在更新到tns核心模块2.2.0和angular rc4（telerik正式发布的版本）时，我的应用程序无法再对服务器进行http调用，我一直收到这个错误

com.tns.NativeScriptException:

我一直在网上寻找更新的发布日志，看看是否有任何突破性的变化，但没有结果。有人对如何使用新的nativescript angular更新进行http调用有任何指导吗

谢谢

您需要在main.ts文件中使用此代码

import {Parse5DomAdapter} from '@angular/platform-server/src/parse5_adapter';

(<any>Parse5DomAdapter).prototype.getCookie = function (name) { return null; };

从'@angular/platform server/src/parse5_adapter'导入{Parse5DomAdapter}；
（Parse5DomAdapter）.prototype.getCookie=函数（名称）{returnnull；}；

我通过在

app.moude.ts

中导入以下内容来修复此问题

import {NativeScriptHttpModule} from 'nativescript-angular/http';

然后

 imports: [NativeScriptHttpModule]

我不知道这是否真的能解决您的问题，但github上有一个开放的问题：谢谢，我发现了这个问题，并使用了Nathan的建议，它成功了。您必须在main.ts中引导NS_HTTP_提供程序，并确保在两个package.json文件中将nativescript angular的版本设置为“next”。npm安装和构建。这应该可以解决问题。哪个是“other”package.json文件？

文件夹中的那个？是的，是
