稍微解释一下:
manifest.json 是来描述chrome扩展的
{
"version": "1.0.0",
"manifest_version": 2,
"name": "Chrome Fiddler",
"permissions": [
"proxy",
"tabs",
"unlimitedStorage",
"storage",
"<all_urls>",
"webRequest",
"webRequestBlocking"
],
"background": {
"scripts": ["background.js"]
},
"minimum_chrome_version":"22.0.0"
}
background.js 是逻辑处理模块
因为拦截api 或者 转发 需要用的chrome的api
chrome.webRequest.onBeforeRequest.addListener(
function(details) {
//逻辑处理
},
{ urls: ['<all_urls>']},
['blocking', 'extraHeaders', 'requestBody']
);
这个api的函数 接收的details参数
函数的返回
写selenium.chrome插件
新建一个netstand工程,然后引用
复制以下代码
/// <summary>
/// Add Fiddler extention
/// </summary>
/// <param name="options">Chrome options</param>
/// <param name="fiddlerOption">Proxy host</param>
public static void AddFiddler(this ChromeOptions options, FiddlerOption fiddlerOption)
{
var backgroundProxyJs = ReplaceTemplates(background_js, fiddlerOption);
if (!Directory.Exists("Plugins"))
Directory.CreateDirectory("Plugins");
var guid = Guid.NewGuid().ToString();
var manifestPath = $"Plugins/manifest_{guid}.json";
var backgroundPath = $"Plugins/background_{guid}.js";
var archiveFilePath = $"Plugins/proxy_auth_plugin_{guid}.zip";
File.WriteAllText(manifestPath, manifest_json);
File.WriteAllText(backgroundPath, backgroundProxyJs);
using (var zip = ZipFile.Open(archiveFilePath, ZipArchiveMode.Create))
{
zip.CreateEntryFromFile(manifestPath, "manifest.json");
zip.CreateEntryFromFile(backgroundPath, "background.js");
}
File.Delete(manifestPath);
File.Delete(backgroundPath);
options.AddExtension(archiveFilePath);
}
private static string ReplaceTemplates(string str, FiddlerOption fiddlerOption)
{
if (fiddlerOption.OnBeforeRequestOptions != null)
{
var beforeConfigs = Newtonsoft.Json.JsonConvert.SerializeObject(fiddlerOption.OnBeforeRequestOptions);
str = str.Replace("{before_configs}", beforeConfigs);
}
return str;
}
上面的代码主要是创建一个chrome扩展zip包
然后再selenium.chrome启动的时候传进去这个zip包的地址
使用方法
var driverBinary = @"D:\soft\chrome\chrome2\Chrome-bin\";
ChromeOptions options = new ChromeOptions
{
BinaryLocation = Path.Combine(driverBinary, "chrome.exe")
};
Environment.SetEnvironmentVariable("webdriver.chrome.driver", driverBinary);
options.AddArgument("--disable-blink-features=AutomationControlled");
options.AddArguments("--disable-infobars");
List<string> ls = new List<string> { "enable-automation" };
options.AddExcludedArguments(ls);
#region Fillder
options.AddFiddler(new FiddlerOption
{
OnBeforeRequestOptions = new List<FiddlerOnBeforeRequestOptions>
{
// 配置转发
new FiddlerOnBeforeRequestOptions
{
Match = "https://www.cnblogs.com/yudongdong/ajax/GetPostStat",//正则
RedirectUrl = "http://localhost:5000/GetPostStat",//如果匹配成功则将requestBody转发到这个url中去
Cancel = false//如果配置了cancel=true那么转发将无效,true的意思是直接拦截这次的请求,不去发送了
},
// 配置拦截
new FiddlerOnBeforeRequestOptions
{
Match = "https://www.cnblogs.com/yudongdong/ajax/blogStats",
Cancel = true//true的意思是直接拦截这次的请求,不去发送了
},
}
});
#endregion
var chrome = new ChromeDriver(driverBinary, options);
