如何通過https從.NET使用Redmine REST API？

Question

我們內部的Redmine服務器只允許我通過HTTPS進行連接。以下是我試圖通過HTTPS從.NET使用REST API：

1. 作爲Using the REST API with .NET建議，設置主機變量"https://redmine.company.com/redmine/"和apiKey到"ffffffffffffffffffffffffffffffffffffffff"。

2. 從無到有用下面的代碼：

   using System.IO; 
   using System.Net; 
   
   class Program 
   { 
       static void Main(string[] args) 
       { 
        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, error) => true; 
   
        var request = (HttpWebRequest)WebRequest.Create(
         "https://redmine.company.com/redmine/issues/149.xml?key=ffffffffffffffffffffffffffffffffffffffff"); 
        request.CookieContainer = new CookieContainer(); 
        request.Method = "GET"; 
   
        using (var response = request.GetResponse()) // Hangs here 
        using (var responseStream = response.GetResponseStream()) 
        using (var memoryStream = new MemoryStream()) 
        { 
         responseStream.CopyTo(memoryStream); 
        } 
       } 
   } 
   

當然，company.com和ffffffffffffffffffffffffffffffffffffffff是我真實的公司和我的帳戶頁面上我真正的API密鑰只是佔位符。在WebException超時之前，這兩種嘗試都會暫停一段時間（請參閱在嘗試2中掛起評論）。然後我嘗試從Redmine服務器上下載其他東西（例如time_entries.csv，atom feed等），每次都得到完全相同的結果。

到目前爲止那麼糟糕。但是，如果我將URL https://redmine.company.com/redmine/issues/149.xml?key=ffffffffffffffffffffffffffffffffffffffff複製粘貼到我的瀏覽器中，我就會得到我期望的響應。所以，好像我們的Redmine服務器的行爲應該如此，但不知何故，我無法從.NET中使用它。

我已成功從其他HTTPS網站下載了內容，並已嘗試從http://demo.redmine.org下載問題數據，其中包含嘗試2的代碼（當然還包括改編的URL等）。因此，Redmine如何通過HTTPS進行通信似乎有些特別之處。

如果有人成功使用從.NET Redmine的REST API通過HTTPS，我是什麼，我做錯了一些三分球真的很感激。

此外，關於如何從客戶端調試這個建議，將不勝感激。到目前爲止，我已經嘗試過Fiddler2，沒有成功。只要我啓用其「解密HTTPS流量」設置，當我在Internet   Explorer中提出請求時，我將不再得到答案。

Answer 1

我們使用redmine-net-api它支持HTTP/S連接和認證基於API密鑰。

     RedmineManager rm = new RedmineManager("https://&ltyour-address>", &ltapi-key>, "random-password"); 
     IList&ltIssue> issues = rm.GetObjectList&ltIssue>(new NameValueCollection() { { "project_id", &ltproject-id> } });

試試這個，它爲我工作：

// Allow every secure connection 
ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, error) => true; 

// Create redmine manager (where URL is "https://10.27.10.10/redmine" for me and redmineKey is my redmine API key 
RedmineManager redmineManager = new RedmineManager(redmineURL, redmineKey); 

// Create your query parameters 
NameValueCollection queryParameters = new NameValueCollection { { "project_id", "4" }, {"tracker_id", "17"}, { "offset", "0" } }; 

// Perform your query 
int issuesFound = 0; 
foreach (var issue in redmineManager.GetObjectList<Issue>(queryParameters, out issuesFound)) 
{ 
// By default you get the 25 first issues of the project_id and tracker_id specified. 
// Play with the offset to get the rest 
queryParameters["offset"] = .... 
}

爲securityProtocolType參數明確傳遞SecurityProtocolType.Tls12值解決了我的情況的問題：我只是試着用你的代碼

RedmineManager redmineManager = new RedmineManager(_host, _apiKey, 
    securityProtocolType: SecurityProtocolType.Tls12);
