第selenium.chrome寫(xiě)擴(kuò)展攔截或轉(zhuǎn)發(fā)請(qǐng)求功能目錄Selenium.WebDrivernuget開(kāi)始coding寫(xiě)selenium.chrome插件使用方法實(shí)現(xiàn)效果

Selenium.WebDriver

SeleniumWebDriver是一組開(kāi)源API，用于自動(dòng)測(cè)試Web應(yīng)用程序，利用它可以通過(guò)代碼來(lái)控制chrome瀏覽器！

有時(shí)候我們需要mock接口的返回，或者攔截和轉(zhuǎn)發(fā)請(qǐng)求，今天就來(lái)實(shí)現(xiàn)這個(gè)功能

代碼已開(kāi)源：/yuzd/OpenQA.Selenium.Chrome.Fiddler

nuget

OpenQA.Selenium.Chrome.Fiddler

開(kāi)始coding

我們新創(chuàng)建一個(gè)功能：OpenQA.Selenium.Chrome.Fiddler

一個(gè)chrome擴(kuò)展最起碼有2個(gè)文件

manifest.json

background.js

稍微解釋一下：

manifest.json是來(lái)描述chrome擴(kuò)展的

{

"version":"1.0.0",

"manifest_version":2,

"name":"ChromeFiddler",

"permissions":[

"proxy",

"tabs",

"unlimitedStorage",

"storage",

"all_urls",

"webRequest",

"webRequestBlocking"

"background":{

"scripts":["background.js"]

"minimum_chrome_version":"22.0.0"

}

background.js是邏輯處理模塊

因?yàn)閿r截api或者轉(zhuǎn)發(fā)需要用的chrome的api

chrome.webRequest.onBeforeRequest.addListener(

function(details){

//邏輯處理

{urls:['all_urls']},

['blocking','extraHeaders','requestBody']

);

這個(gè)api的函數(shù)接收的details參數(shù)

details.url是api的接口

函數(shù)的返回

{cancel:true}攔截請(qǐng)求{redirectUrl:}轉(zhuǎn)發(fā)到指定url

寫(xiě)selenium.chrome插件

新建一個(gè)netstand工程，然后引用

Selenium.WebDriver

復(fù)制以下代碼

///summary

///AddFiddlerextention

////summary

///paramname="options"Chromeoptions/param

///paramname="fiddlerOption"Proxyhost/param

publicstaticvoidAddFiddler(thisChromeOptionsoptions,FiddlerOptionfiddlerOption)

varbackgroundProxyJs=ReplaceTemplates(background_js,fiddlerOption);

if(!Directory.Exists("Plugins"))

Directory.CreateDirectory("Plugins");

varguid=Guid.NewGuid().ToString();

varmanifestPath=$"Plugins/manifest_{guid}.json";

varbackgroundPath=$"Plugins/background_{guid}.js";

vararchiveFilePath=$"Plugins/proxy_auth_plugin_{guid}.zip";

File.WriteAllText(manifestPath,manifest_json);

File.WriteAllText(backgroundPath,backgroundProxyJs);

using(varzip=ZipFile.Open(archiveFilePath,ZipArchiveMode.Create))

zip.CreateEntryFromFile(manifestPath,"manifest.json");

zip.CreateEntryFromFile(backgroundPath,"background.js");

File.Delete(manifestPath);

File.Delete(backgroundPath);

options.AddExtension(archiveFilePath);

privatestaticstringReplaceTemplates(stringstr,FiddlerOptionfiddlerOption)

if(fiddlerOption.OnBeforeRequestOptions!=null)

varbeforeConfigs=Newtonsoft.Json.JsonConvert.SerializeObject(fiddlerOption.OnBeforeRequestOptions);

str=str.Replace("{before_configs}",beforeConfigs);

returnstr;

}

上面的代碼主要是創(chuàng)建一個(gè)chrome擴(kuò)展zip包

然后再selenium.chrome啟動(dòng)的時(shí)候傳進(jìn)去這個(gè)zip包的地址

使用方法

vardriverBinary=@"D:\soft\chrome\chrome2\Chrome-bin\";

ChromeOptionsoptions=newChromeOptions

BinaryLocation=Path.Combine(driverBinary,"chrome.exe")

Environment.SetEnvironmentVariable("webdriver.chrome.driver",driverBinary);

options.AddArgument("--disable-blink-features=AutomationControlled");

options.AddArguments("--disable-infobars");

Liststringls=newListstring{"enable-automation"};

options.AddExcludedArguments(ls);

#regionFillder

options.AddFiddler(newFiddlerOption

OnBeforeRequestOptions=newListFiddlerOnBeforeRequestOptions

//配置轉(zhuǎn)發(fā)

newFiddlerOnBeforeRequestOptions

Match="/yudongdong/ajax/GetPostStat",//正則

RedirectUrl="http://localhost:5000/GetPostStat",//如果匹配成功則將requestBody轉(zhuǎn)發(fā)到這個(gè)url中去

Cancel=false//如果配置了cancel=true那么轉(zhuǎn)發(fā)將無(wú)效，true的意思是直接攔截這次的請(qǐng)求,不去發(fā)送了

//配置攔截

newFiddlerOn
