提琴手 - 發送代理客戶端請求

Question

我有提琴手配置爲反向代理，以充當一個人在客戶端和服務器之間的中間。我有一個自定義規則，將發送給予一定的響應URI來自代理的請求：

static function OnBeforeResponse(oSession: Session) { 
    ... 
    if (oSession.uriContains("something.aspx")) { 

     var request = "..." 
     FiddlerObject.utilIssueRequest(request); 
    } 
... 
} 

有什麼辦法來路由通過utilIssueRequest發出返回給客戶機的請求？

Answer 1

你可以，但這樣做非常複雜。通常情況下，您只需修改OnBeforeRequest處理程序中的請求，以便URL/Host頭指向新的目標服務器。

Answer 2

我很抱歉 - 我的問題最終要求比我在提問時意識到的更多細節。如果有人有興趣，我用這個奇怪的方法解決了這個問題：

拓撲：Windows客戶端 - > Fiddler代理在Windows客戶端 - > Fiddler反向代理中間人 - > Windows服務器

代碼在Windows客戶端CustomRules.js：

static function OnBeforeRequest(oSession: Session) { 

    //detect prefetch response 
    if (oSession.oRequest.headers.Exists("X-FiddlerPrefetch")) { 
     //dump response into a variable 
     oSession.utilDecodeRequest(); 
     prefetchResponse = System.Text.Encoding.UTF8.GetString(oSession.requestBodyBytes); 
    } 

    //detect uri that was prefetched 
    if (oSession.uriContains("/some_uri")) { 
     //wait for prefetch - cant find any docs for how to 'sleep' here 
     // while (prefetchResponse === "") { 
      // Sleep(1); 
     // } 

     //use cached response 
     oSession.utilCreateResponseAndBypassServer(); 
     oSession.utilSetResponseBody(prefetchResponse); 

    } 

    //redirect traffic to man-in-the-middle 
    if (oSession.HostnameIs("some_server")) { 
     oSession["x-overrideHost"] = "man-in-the-middle:443"; 
    } 
... 

守則人在這方面的中間人CustomRules.js：

static function OnBeforeResponse(oSession: Session) { 

    //intercept response containing prefetch material 
    if (oSession.uriContains("some_response")) { 

     //parse response body for some prefetch info 
     ... 

     //compose request 
     var request = "POST " + uri + " HTTP/1.1" + "\n" + 
     "X-FiddlerOpt: test\n" + 
     ... 

     //send off to server 
     FiddlerObject.utilIssueRequest(request); 
    } 


    //detect the prefetch response, send to client 
    if (oSession.oRequest.headers.Exists("X-FiddlerOpt")) { 

     oSession.utilDecodeResponse(); 
     var payload = System.Text.Encoding.UTF8.GetString(oSession.responseBodyBytes);; 

     //compose request 
     var request = "GET " + "http://windows_client:8888/ HTTP/1.1" + "\n" + 
     "Content-Length: " + payload.length + "\n" + 
     "X-FiddlerPrefetch: test\n" + 
     "\n" + 
     payload 

     //send request 
     FiddlerObject.utilIssueRequest(request); 
    } 
... 

正如我敢肯定有更簡單的或更好的方法做這個，歡迎任何反饋。
