Question

我按照角网站中提到的一步一步做了所有事情，仍然没有请求代理。

8080 - 我的springboot app和后端4200 - 我的Angular2前端

在Angular2项目中，我有文件proxy.cons.json，内容如下：

{
  "/api": {
     "target": "http://localhost:8080",
     "secure": false,
     "changeOrigin": true,
     "logLevel": "debug"
  }
}

在Angular2 package.json中，我将启动过程更改为＆＃34;启动＆＃34;：＆＃34; ng serve --proxy-config proxy.conf.json＆＃34;

当我在指挥官内部键入npm start然后在开始时我可以看到代理创建：/ api - ＆gt; http://localhost:8080。好吧，到目前为止我觉得很好。

我试图发送请求（Angular2）

以下是我的service.ts文件

   import { Injectable } from '@angular/core';
import { Headers, Http } from '@angular/http';
import 'rxjs/add/operator/toPromise';

@Injectable()
export class SpipService 
{

  constructor(private http: Http) { }

  callRest():  Promise<string> {
    let context:String =  window.location.pathname.split('/').slice(0,-1).join('/');
    console.log("Please check--------------->");
    return this.http.get("/api/serviceContext/rest/hello/")
      .toPromise()
      .then(response => response.text() as string)
      .catch(this.handleError);
  }

    private handleError(error: any): Promise<any> {
    console.error('Some error occured', error);
    return Promise.reject(error.message || error);
  }
}

的package.json：

  "name": "angular",
  "version": "0.0.0",
  "license": "MIT",
  "scripts": {
    "ng": "ng",
    "start": "ng serve --proxy-config proxy.conf.json",

    "ts-node": "~4.1.0",

  }
}

我收到http://localhost:4200/api/serviceContext/rest/hello/ 404（未找到）的错误。我们可以看到，没有任何代理。为什么？

要清楚。当我手动去，一切正常。请指导。

Answer 1

你的JSON应该是这个

{
  "/api": {
     "target": "http://localhost:8080",
     "secure": false,
     "changeOrigin": true,
     "logLevel": "debug"
  }
}

让您的通话看起来像这样

return this.http.get("/api/serviceContext/rest/hello/").

编辑我自己的配置：

{
  "/api": {
    "target": "http://private-url-your-peeker:8765/",
    "secure": false,
    "changeOrigin": true,
    "logLevel": "debug"
  }
}

我的电话

return this.http.get("api/serviceContext/rest/hello/").

Answer 2

在我按proxy.conf.json修改后，所有事情似乎都运作良好。希望它能帮助将来的人：

{
  "/api/*": {
    "target": "http://localhost:8080",
    "secure": false,
    "pathRewrite": {"^/api" : ""},
    "changeOrigin": true,
    "logLevel": "debug"
  }
}

后端的角度代理不起作用？
