nginx: the configuration file e:\web-server-for-win\nginx-1.13.8/conf/nginx.conf syntax is ok

2.angular 5 

1). install nodejs

node-v8.9.3-x64.msi

2).setting prog

由于 npm 官网镜像国内访问太慢，这里我使用了淘宝的npm镜像，安装方法如下：

$ npm install -g cnpm --registry=https://registry.npm.taobao.org

执行后我们就可以使用 cnpm 命令来安装模块：

$ npm install -g @angular/cli@latest

项目初始化

新建项目

E:\>ng new pgmon-web --routing

选项：

--routing，附加路由功能

E:\>cd pgmon-web

新建组件(默认每个组件单独生成文件夹)

E:\pgmon-web>ng g c login

E:\pgmon-web>ng g c dashboard

新建服务(每个服务单独生成生成文件夹)

E:\pgmon-web> ng g s --flat false AuthGuard

  create src/app/auth-guard/auth-guard.service.spec.ts (393 bytes)

  create src/app/auth-guard/auth-guard.service.ts (115 bytes)

E:\pgmon-web> ng g s --flat false AuthenticationService

  create src/app/authentication-service/authentication-service.service.spec.ts (465 bytes)

  create src/app/authentication-service/authentication-service.service.ts (127 bytes)

E:\pgmon-web> ng g s --flat false UserService

  create src/app/user-service/user-service.service.spec.ts (405 bytes)

  create src/app/user-service/user-service.service.ts (117 bytes)

E:\pgmon-web>

安装node模块

E:\pgmon-web> npm install bootstrap@next

选项：

@next，使用最新版本4.0.0-beta.2，否则使用版本3

npm WARN bootstrap@4.0.0-beta.2 requires a peer of jquery@1.9.1 - 3 but none is installed. You must install peer dependencies yourself.

npm WARN bootstrap@4.0.0-beta.2 requires a peer of popper.js@^1.12.3 but none is installed. You must install peer dependencies yourself.

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.3 (node_modules\fsevents):

npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})

+ bootstrap@4.0.0-beta.2

added 115 packages, removed 5 packages and updated 2 packages in 23.201s

E:\pgmon-web>

加载bootstrap到angular组件

E:\pgmon-web>目录，编辑.angular-cli.json文件

      "styles": [

        "styles.css",

        "../node_modules/bootstrap/dist/css/bootstrap.css"

      ],

      

生成生产环境部署文件,E:\pgmon-web\dist

E:\pgmon-web>ng build --prod

Dep is a tool for managing dependencies for Go projects

Usage: "dep [command]"

Commands:

  init     Initialize a new project with manifest and lock files

  status   Report the status of the project's dependencies

  ensure   Ensure a dependency is safely vendored in the project

  prune    Prune the vendor tree of unused packages

  version  Show the dep version information

Examples:

  dep init                               set up a new project

  dep ensure                             install the project's dependencies

  dep ensure -update                     update the locked versions of all dependencies

  dep ensure -add github.com/pkg/errors  add a dependency to the project

Use "dep help [command]" for more information about a command.

安装项目依赖包(安装前必须先进行dep初始化)

E:\go-web\src\app> e:\go-web\bin\dep ensure

运行项目

E:\go-web\src\app> go run main.go

打开浏览器，

输入"localhost/api/status"

或者"localhost:8000/api/status"

browser output:

{"data":"Golang API Server run successfull."}
