本文介绍如何在Angular项目中设置代理，通过配置proxy.conf.json文件实现API请求转发，并展示了如何在service中正确引用这些代理路径。

1. 新建proxy.conf.json 文件内容如下：

{
    "/api": {
        "target": "http://124.77.3.162:8888",
        "secure": false,
        "router" : {
        "/v1/index": "http://125.78.3.162:8888",
        "/v1/finances": "http://124.77.3.162:8888"
     }              
    }
}

上面代码最终访问结果：http://124.77.3.162:8888/api/v1/finances

2. 在package.json文件中引入代理文件修改scripts 的 start

{
  "name": "yqfx",
  "version": "0.0.0",
  "license": "MIT",
  "angular-cli": {},
  "scripts": {
    "ng": "ng",
    "start": "ng serve --sourcemap=false--host 0.0.0.0 --proxy-config proxy.conf.json",
    "test": "ng test",
    "pree2e": "webdriver-manager update --standalone false --gecko false",
    "e2e": "protractor"
  },
  "private": true,
  "dependencies": {
    "@angular/common": "^2.3.1",
    "@angular/compiler": "^2.3.1",
    "@angular/core": "^2.3.1",
    "@angular/forms": "^2.3.1",
    "@angular/http": "^2.3.1",
    "@angular/platform-browser": "^2.3.1",
    "@angular/platform-browser-dynamic": "^2.3.1",
    "@angular/router": "^3.3.1",
    "core-js": "^2.4.1",
    "echarts-ng2": "^1.4.1",
    "primeng": "1.1.4",
    "rxjs": "^5.0.1",
    "ts-helpers": "^1.1.1",
    "zone.js": "^0.7.2"
  },
  "devDependencies": {
    "@angular/compiler-cli": "^2.3.1",
    "@types/echarts": "0.0.9",
    "@types/jasmine": "2.5.38",
    "@types/node": "^6.0.42",
    "angular-cli": "1.0.0-beta.28.3",
    "codelyzer": "~2.0.0-beta.1",
    "jasmine-core": "2.5.2",
    "jasmine-spec-reporter": "2.5.0",
    "karma": "1.2.0",
    "karma-chrome-launcher": "^2.0.0",
    "karma-cli": "^1.0.1",
    "karma-jasmine": "^1.0.2",
    "karma-remap-istanbul": "^0.2.1",
    "protractor": "~4.0.13",
    "ts-node": "1.2.1",
    "tslint": "^4.3.0",
    "typescript": "~2.0.3"
  }
}

3. 在service中地址写法如下，就能匹配到 http://124.77.3.162:8888/api/v1/finances

getConditionList(id): Promise<any> {

    let headers = new Headers({
      'Content-Type': 'application/json'
    });
    return this.http
      .get("/api/v1/finances/getCondition", { headers: headers })
      .toPromise()
      .then(response => {
        return response.json() as any;
      })
      .catch(this.handleError);
  }
