Swagger 实践 <二>

1. 新建.netCore WebApi 项目（选择Angular）。按照上一篇的加上Swage 文档，使http://localhost:11934/swagger/v1/swagger.json 可以访问。

2.新建 一个文件夹nswag，里面有3个文件

1.     refresh.bat   ：  ".. ode_modules.bin swag" run
2.    service.config.nswag，注意修改地址

3. service.extensions.ts ：import 'rxjs/add/operator/finally';

3.在package.json 中添加  "nswag": "^11.18.6"

   执行  npm install .如果安装不上，可以改变下仓库：npm set registry https://registry.npm.taobao.org/  参考这里

4. 运行后端。

    双击运行nswag 下的refresh.bat  就可以生成 service-proxies.ts

 5.原理跟踪：

• . ode_modules.bin swag 如下；

  @IF EXIST "%~dp0
  ode.exe" (
    "%~dp0
  ode.exe"  "%~dp0..
  swagin
  swag.js" %*
  ) ELSE (
    @SETLOCAL
    @SET PATHEXT=%PATHEXT:;.JS;=;%
    node  "%~dp0..
  swagin
  swag.js" %*
  )

• nswag.js：

  #!/usr/bin/env node
  "use strict";
  
  var defaultCoreVersion = "11";
  var supportedCoreVersions = ["10", "11", "20", "21"];
  
  // Initialize
  process.title = 'nswag';
  console.log("NSwag NPM CLI");
  var args = process.argv.splice(2, process.argv.length - 2).map(function (a) { return a.indexOf(" ") === -1 ? a : '"' + a + '"' }).join(" ");
  
  // Legacy support
  args = args.replace("--x86", "/runtime:WinX86");
  args = args.replace("/runtime:x86", "/runtime:WinX86");
  args = args.replace("--core 1.0", "/runtime:NetCore10");

      }
      catch (e) {

      var defaultCmd = 'dotnet "' + __dirname + '/binaries/NetCore' + defaultCoreVersion + '/dotnet-nswag.dll" ' + args;
      var infoCmd = "dotnet --version";
      c.exec(infoCmd, (error, stdout, stderr) => {
          for (let version of supportedCoreVersions) {
              var coreCmd = 'dotnet "' + __dirname + '/binaries/NetCore' + version + '/dotnet-nswag.dll" ' + args;
  
              if (args.toLowerCase().indexOf("/runtime:netcore" + version) != -1) {
                  c.execSync(coreCmd, { stdio: [0, 1, 2] });
                  return;
              } else {
                  if (!error) {
                      var coreVersion = stdout;
                      if (coreVersion.indexOf(version + ".0") !== -1) {

                          return;
                      }
                  }
              }
          }
