Angular4 + Hprose-nodejs

Hprose - http://github.com/hprose

到了今天，如果你还不知道Hprose的话，请自觉去面壁 ^_。

今天，我们聊聊如何在Angular4中使用Hprose。

1、在Mac上你需要安装 brew https://brew.sh/

2、安装node.js ( https://nodejs.org/en/download/ )。

如果你也是用Mac，那么安装就很简单啦。

brew install node yarn

查看是否安装成功

node -v
v7.9.0

npm -v
4.2.0

设置默认淘宝源

npm config set registry https://registry.npm.taobao.org
yarn config set registry 'https://registry.npm.taobao.org'

3、安装 Angular-Cli

npm i -g @angular/cli

查看是否安装成功

ng -v

   / \   _ __   __ _ _   _| | __ _ _ __     / ___| |   |_ _|
  / △ \ | '_ \ / _` | | | | |/ _` | '__|   | |   | |    | |

/_/   \_\_| |_|\__, |\__,_|_|\__,_|_|       \____|_____|___|
               |___/
@angular/cli: 1.0.1
node: 7.9.0
os: darwin x64

默认使用Yarn安装

ng set --global packageManager=yarn

4、创建Ng项目

首先我们需要创建个hprose-ng的项目。

ng new hprose-ng

installing ng
  create .editorconfig
  create README.md
  create src/app/app.component.css
  create src/app/app.component.html
  create src/app/app.component.spec.ts
  create src/app/app.component.ts
  create src/app/app.module.ts
  create src/assets/.gitkeep
  create src/environments/environment.prod.ts
  create src/environments/environment.ts
  create src/favicon.ico
  create src/index.html
  create src/main.ts
  create src/polyfills.ts
  create src/styles.css
  create src/test.ts
  create src/tsconfig.app.json
  create src/tsconfig.spec.json
  create src/typings.d.ts
  create .angular-cli.json
  create e2e/app.e2e-spec.ts
  create e2e/app.po.ts
  create e2e/tsconfig.e2e.json
  create .gitignore
  create karma.conf.js
  create package.json
  create protractor.conf.js
  create tsconfig.json
  create tslint.json
Successfully initialized git.

Project 'hprose-ng' successfully created.

5、添加hprose组件

cd hprose-ng && npm i hprose utf-8-validate bufferutil --save

hprose-ng@0.0.0 /www/Angularjs/hprose-ng
└─┬ hprose@2.0.42
  └─┬ ws@2.0.3
    └── ultron@1.1.0

6、创建ng hprose 服务

ng g s api

installing service
  create src/app/api.service.spec.ts
  create src/app/api.service.ts
  WARNING Service is generated but not provided, it must be provided to be used

7、编辑 app/api.service.ts

import { Injectable } from '@angular/core';
import hprose from 'hprose';

@Injectable()
export class ApiService {

  get(funcName: string): any {
        let client: any = hprose.HttpClient('http://hprose.com/example/', [funcName]);
        return client;
    }

}

app/app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { AppComponent } from './app.component';
import { ApiService } from './api.service';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule
  ],
  providers: [ApiService],
  bootstrap: [AppComponent]
})
export class AppModule { }

8、使用hprose server发布的方法 app/app.component.ts

import { Component } from '@angular/core';
import { ApiService } from './api.service';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'app works!';
  api: any;

  constructor(api: ApiService) {
    let cli = api.get("hello");
    cli.hello("laoliu").then((result) => {
      console.log(result);
    }, (name, err) => {
      console.log(name, err);
    });
  }
}

9、现在你就可以在Ng组件中使用hprose啦。

ng serve
