Miniprofiler在swagger、vue、angular中的使用

 本篇分为以下几个部分:

  • 1.Swagger的简单应用
  • 2.Miniprofier的后台配置
  • 3.跨域配置
  • 4.在angular中显示Miniprofier
  • 5.在vue中显示Miniprofier
  • 6.在swagger中显示Miniprofier

 

Swagger的简单应用

1、首先新建一个Api项目

2、使用Nuget添加Swashbuckle.AspNetCore,我使用的版本为1.1.0( 版本不一样,后面的配置可能不一样
 
3、为了在swagger上显示注释,右键项目MiniprofilerApi,属性=>生成=>输出为XML文档文件
 
4、右键项目=>编辑.csproj添加如下代码,避免一些警告:
 

 

4、在Startup类的ConfigureServices方法和Configure方法中配置如下:

5、添加接口注释:

6、修改项目运行端口,访问路径,关闭ssl,右键项目=>属性=>调试,配置如下:

7、启动项目,界面效果如下:

Miniprofier的后台配置

1、安装MiniProfiler.AspNetCore.Mvc

2、在Startup类的ConfigureServices方法和Configure方法中配置如下:

3、运行程序:访问http://localhost:5000/mini-profiler-resources/results

在angular中显示Miniprofier

1、在页面创建Miniprofier需要的js和css

import { Component } from '@angular/core';
import { HttpClient } from '@angular/common/http';


@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  private src: string = 'http://localhost:5000/mini-profiler-resources/';
  private scriptSrc: string = `${this.src}includes.min.js`;
  private cssSrc: string = `${this.src}includes.min.css`;

  private id: string = 'mini-profiler';
  private dataPath: string = `${this.src}`;
  private dataVersion: string = '';
  private dataPosition: string = 'right';
  private dataChildren: boolean = true;
  private dataMaxTraces: number = 35;
  private dataAuthorized: boolean = true;
  private dataStartHidden: string = 'false';
  private dataToggleShortcut: string = 'Alt+P';
  private dataTrivialMilliseconds: number = 35;
  private dataTrivial: boolean = true;
  private dataControls: boolean = true;
  private dataCurrentId: string = '';
  private dataIds: string = '';
  private scriptAsync: boolean = true;
  private innerHTML: string = '';

  constructor(private http: HttpClient){
  }

  ngAfterViewInit(): void {
    //添加Miniprofier的js
    this.appendDivElement();
    //添加Miniprofier的css
    this.appendCssLink();
  }

  //请求后台接口
  send(): void{
    let serverurl: string = "http://localhost:5000//api/Values";

    this.http.get(serverurl)
    .toPromise()
    .then(response => {
      console.log()
    }).catch(error => {
    });
  }

  private appendDivElement(): void {
    const body = document.body as HTMLDivElement;
    const script = document.createElement('script');
    script.innerHTML = this.innerHTML;
    script.src = this.scriptSrc;
    script.setAttribute('data-version', this.dataVersion);
    script.setAttribute('data-path', this.dataPath);
    script.setAttribute('data-position', this.dataPosition);
    script.setAttribute('id', this.id);
    script.setAttribute('data-current-id', this.dataCurrentId);
    script.setAttribute('data-ids', this.dataIds);
    script.setAttribute('data-trivial', this.dataTrivial.toString());
    script.setAttribute('data-children', this.dataChildren.toString());
    script.setAttribute('data-max-traces', this.dataMaxTraces.toString());
    script.setAttribute('data-controls', this.dataControls.toString());
    script.setAttribute('data-authorized', this.dataAuthorized.toString());
    script.setAttribute('data-start-hidden', this.dataStartHidden.toString());
    script.setAttribute('data-toggle-shortcut', this.dataToggleShortcut);
    script.setAttribute('data-trivial-milliseconds', this.dataTrivialMilliseconds.toString());
    script.async = this.scriptAsync;
    body.appendChild(script);
  }

  private appendCssLink(): void {
      const body = document.body as HTMLDivElement;
      const css = document.createElement('link');
      css.href = this.cssSrc;
      css.rel = 'stylesheet';

      body.appendChild(css);
  }
}
View Code

2、添加Http拦截器,动态显示监听结果

import { Injectable } from '@angular/core';
import { HttpInterceptor, HttpHandler, HttpRequest, HttpEvent, HttpResponse, HttpHeaders }
  from '@angular/common/http';

import { Observable } from 'rxjs';
import { tap } from 'rxjs/operators';

declare var MiniProfiler: any;

@Injectable()
export class MiniProfilerInterceptor implements HttpInterceptor {
  intercept(
    req: HttpRequest,
    next: HttpHandler
  ): Observable> {
    return next.handle(req).pipe(
        tap(evt => {
            if (evt instanceof HttpResponse) {
              if (evt && evt.headers) {
                this.makeMiniProfilerRequests(evt.headers);
              }
            }
          })
    )
  }

  private makeMiniProfilerRequests(headers: HttpHeaders) {
    const miniProfilerHeaders = headers.getAll('x-miniprofiler-ids');

    if (!miniProfilerHeaders) {
      return;
    }

    miniProfilerHeaders.forEach(miniProfilerIdHeaderValue => {
      const ids = JSON.parse(miniProfilerIdHeaderValue) as string[];
      MiniProfiler.fetchResults(ids);
    });

  }
}
View Code

3、在app.module.ts中的配置

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';
import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
import { MiniProfilerInterceptor } from './mini-profiler-http';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    HttpClientModule
  ],
  providers: [{
    provide: HTTP_INTERCEPTORS,
    useClass: MiniProfilerInterceptor, multi: true
  }],
  bootstrap: [AppComponent]
})
export class AppModule { }
View Code

4、在app.component.html页面添加一个请求按钮

View Code

5、页面效果

在vue中显示Miniprofier

和在angular中的操作步骤一致,下面放主要代码:

1、App.vue 主组件





View Code

 

2、Dummy.vue 子组件用于发送接口请求



View Code

 

3、MiniProfiler.vue 子组件用于添加拦截器和创建Miniprofier需要的js和css



View Code

 

4、界面效果

在swagger中显示Miniprofier

1、将性能分析监测信息从后端发送到Swagger界面。

首先给swagger添加拦截器

拦截器代码如下:

using Microsoft.AspNetCore.Http;
using StackExchange.Profiling;
using Swashbuckle.AspNetCore.Swagger;
using Swashbuckle.AspNetCore.SwaggerGen;

namespace MiniprofilerApi.MiniProfierHelp
{
    public class InjectMiniProfiler : IDocumentFilter
    {
        private readonly IHttpContextAccessor _httpContext;
        public InjectMiniProfiler(IHttpContextAccessor httpContext)
        {
            _httpContext = httpContext;
        }
        public void Apply(SwaggerDocument swaggerDoc, DocumentFilterContext context)
        {
            swaggerDoc.Info.Contact = new Contact()
            {
                Name = MiniProfiler.Current.RenderIncludes(_httpContext.HttpContext).ToString()
            };
        }
    }
}
View Code

 

此时运行项目,swagger界面显示如下:

2、通过js解析MIniprofier的脚本,代码如下:

(function () {
    window.angular=true;

    //Create a mini profiler script tag with the right properites 
    var MiniProfiler = $('#api_info > div:nth-child(3)').text();

    const attributes = [
        'src', 'data-version', 'data-path', 'data-current-id', 'data-ids',
        'data-position', 'data-trivial-milliseconds', 'data-max-traces',
        'data-authorized', 'data-toggle-shortcut', 'data-ignored-duplicate-execute-types'
    ];

    var GetAttr = function (input, attributeName) {
        const myRegexp = attributeName + '="(.*?)"';
        const re = new RegExp(myRegexp, "g");
        const match = re.exec(input);
        return match[1];
    }
    var s = document.createElement("script");
    s.type = "text/javascript";
    s.id = "mini-profiler";
    s.async = true; 

    for (var i = 0; i < attributes.length; i++) {
        var element = attributes[i];
        s.setAttribute(element, GetAttr(MiniProfiler, element));
    }

    document.body.appendChild(s);

    // Remove injected tag from view 
    $('#api_info > div:nth-child(3)').text('');
})();
View Code

配置swagger执行js:
