如何在angular2中获取http响应状态+返回的数据(how to get http response status + returned data in angular2)

我想在angular2 / ionic2中使用Http。

我的服务代码是

getImageQuestionsFromServer(id:string){ let questions = this._http.get(`http://abcd.com/cbsapp/package_content/${id}/image_questions.json`).map((res: Response) => res.json()); return questions; }

我的组件代码是

this._userDataService.getImageQuestionsFromServer(this.passedPackage.id) .subscribe( (data) => console.log(data.status), (err) => console.log(err) )

我不知道如何检查组件内的Http状态代码。 请帮忙。

最满意答案

服务方式：

getImageQuestionsFromServer(id:string){ return this._http.get(`http://abcd.com/cbsapp/package_content/${id}/image_questions.json`); }

组件方法：

this._userDataService.getImageQuestionsFromServer(this.passedPackage.id) .subscribe( (response) => { let status = response.status let data = response.json(); }, (err) => console.log(err) );

Service method:

getImageQuestionsFromServer(id:string){ return this._http.get(`http://abcd.com/cbsapp/package_content/${id}/image_questions.json`); }

Component method:

this._userDataService.getImageQuestionsFromServer(this.passedPackage.id) .subscribe( (response) => { let status = response.status let data = response.json(); }, (err) => console.log(err) );
