指定的值包含無效的HTTP標頭字符

Question

我試圖從其ASP.NET站點通過其REST API訪問WOWZA流雲，但是對RESTSharp經驗很少。

這是我嘗試創建的curl的示例：

curl -H 'wsc-api-key: KEY' -H 'wsc-access-key: KEY' -H 'Content-Type:
application/json' -X POST -d '{"live_stream": {"name": "MyNewLiveStream",
"transcoder_type": "transcoded", "billing_mode": "pay_as_you_go",
"broadcast_location": "us_west_california", "encoder": "other_rtmp",
"delivery_method": "push", "aspect_ratio_width": 1920,
"aspect_ratio_height": 1080}}'https://api.cloud.wowza.com/api/v1/live_streams/

請參閱： https ： //sandbox.cloud.wowza.com/apidocs/v1/

這是即時通訊使用的C＃代碼：

var client = new RestClient("https://api.cloud.wowza.com/");
        var newRequest = new RestRequest("api/v1/live_streams",Method.POST);
        newRequest.AddHeader("wsc-api-key", ConfigurationManager.AppSettings["WowzaAPIKey"]);
        newRequest.AddHeader("wsc-access-key", ConfigurationManager.AppSettings["WowzaAccessKey"]);
        newRequest.AddHeader("Content-Type", "application/json");
        var body = "{\"live_stream\": {" +
            "\"aspect_ratio_height\": 720," +
            "\"aspect_ratio_width\": 1280," +
            "\"billing_mode\": \"pay_as_you_go\"," +
            "\"broadcast_location\": \"us_west_california\"," +
            "\"closed_caption_type\": \"none\"," +
            "\"delivery_method\": \"push\"," +
            "\"encoder\": \"wowza_gocoder\"," +
            "\"hosted_page\": true," +
            "\"hosted_page_sharing_icons\": true," +
            "\"name\": \"MyLiveStream\"," +
            "\"player_countdown\": false," +
            "\"player_responsive\": true," +
            "\"player_type\": \"original_html5\"," +
            "\"player_width\": 0," +
            "\"recording\": false," +
            "\"target_delivery_protocol\": \"hls\"," +
            "\"transcoder_type\": \"transcoded\"," +
            "\"use_stream_source\": false}";

        newRequest.AddJsonBody(body);
        IRestResponse myResponse = client.Execute(newRequest);

根據響應進行修改后，響應代碼現在為

“ {\\”元\\“：{\\”狀態\\“：401，\\”代碼\\“：\\” ERR-401-InvalidApiKey \\“，\\”標題\\“：\\”無效的API密鑰錯誤\\“，\\” message \\“：\\”無效的API密鑰。\\“，\\”描述\\“：\\” \\“，\\”鏈接\\“：[]}}”

Answer 1

您確定要添加“內容類型”，“ wsc-api-key”和“ wsc-access-key”作為請求參數嗎？

應該將它們添加到請求標頭中，如下所示。

   newRequest.AddHeader("content-type", "Content-Type: application/json");
   newRequest.AddHeader("wsc-api-key:", ConfigurationManager.AppSettings["WowzaAPIKey"]);
   newRequest.AddHeader("wsc-access-key", ConfigurationManager.AppSettings["WowzaAccessKey"]);

Answer 2

你的頭，你不要錯誤車道需要重復的內容類型的值，並移除:從API鍵名：

 newRequest.AddParameter("content-type", "application/json"); 
 newRequest.AddParameter("wsc-api-key", ConfigurationManager.AppSettings["WowzaAPIKey"]);

在OP更新問題時更新

因此，現在修改之后，該呼叫通過並正常運行。 當前錯誤與您傳遞的無效api密鑰有關-可能是您傳遞的訪問密鑰/ api密鑰已被嵌入/過期。

Answer 3

感謝大家的幫助-我現在可以通過C＃包裝的REST API和restsharp與Wowza Cloud Streaming無縫交互。 最后的解決方案是使用Visual Studio函數通過選擇性粘貼生成生成模板JSON類（請參閱在C＃中，如何為具有多個嵌套數組的JSON對象建模？ ）-生成WowzaLivestream類。

然后最后使用此代碼：

_restClient = new RestClient("https://api-sandbox.cloud.wowza.com");
var newRequest = new RestRequest("api/v1/live_streams", Method.POST);
newRequest.RequestFormat = DataFormat.Json;

        newRequest.AddHeader("wsc-api-key", ConfigurationManager.AppSettings["WowzaAPIKey"]);
        newRequest.AddHeader("wsc-access-key", ConfigurationManager.AppSettings["WowzaAccessKey"]);
        newRequest.AddHeader("Content-Type", "application/json");
        newRequest.AddHeader("Accept", "application/json");

        var requestBody = new WowzaLivestream
        {
            live_stream = new Live_Stream
            {
                aspect_ratio_height = 1024,
                aspect_ratio_width = 1900,
                billing_mode = "pay_as_you_go",
                broadcast_location = "eu_ireland",
                closed_caption_type = "none",
                delivery_method = "push",
                encoder = "other_rtmp",
                name = "WowzaLStest2: " + DateTime.Now.ToShortTimeString(),
                player_countdown = true,
                player_responsive = true,
                player_type = "original_html5",
                player_width = 0,
                recording = false,
                target_delivery_protocol = "hls",
                transcoder_type = "transcoded",
                use_stream_source = false
            }
        };

        var json = newRequest.JsonSerializer.Serialize(requestBody);
        newRequest.AddParameter("application/json; charset=utf-8", json, ParameterType.RequestBody);
        IRestResponse myResponse = _restClient.Execute(newRequest);

事實證明，使用的URL是錯誤的-在文檔中沒有特別說明，但是對於沙盒使用，URL是https://api-sandbox.cloud.wowza.com 。
