[英]How to mock an http.get in angular2
Let me explain. 让我解释。
I have this kind of request in "matiere.service.ts" 我在“ matiere.service.ts”中有这种要求
import { Injectable } from '@angular/core';
import {Http, RequestMethod} from '@angular/http';
import 'rxjs/add/operator/toPromise';
@Injectable()
export class MatiereService {
private baseUrl = 'http://localhost:8080/tpFormation-web';
constructor(private http: Http) { }
list() {
return this.http.get(`${this.baseUrl}/matiere`);
}
find(id) {
return this.http.get(`${this.baseUrl}/matiere/${id}`);
}
}
I would like to have something like a fakematiere.service.ts that is creating fake request. 我想创建一个fakematiere.service.ts之类的虚假请求。 I'll lit to do it because the REST api I am connecting to is not coded yet.
我会照做的,因为我要连接的REST api尚未编码。 I have checked around "in-memory-web-api" but I don't know if it's the right tool and tho, I don't really know how to implement it.
我已经检查了“ in-memory-web-api”,但是我不知道它是否是正确的工具,但是,我真的不知道如何实现它。
Any help? 有什么帮助吗?
As per what @Rahul said, if you are only doing gets, a json file is quick and easy. 按照@Rahul所说的,如果您只是做gets,那么json文件又快又容易。
I have an example of using a json file here: https://github.com/DeborahK/Angular2-GettingStarted 我这里有一个使用json文件的示例: https : //github.com/DeborahK/Angular2-GettingStarted
Basically, you just need to change this line of code: 基本上,您只需要更改以下代码行:
private baseUrl = 'http://localhost:8080/tpFormation-web';
To point to your json file. 指向您的json文件。
But if you have put/post/etc, then in memory api is the way to go. 但是,如果您有put / post / etc,那么在内存中使用api是可行的方法。

I did use 我用过
npm install -g json-server
Work perfectly! 完美地工作!
Thanks 谢谢
