我給一個遠程REST service
兩個調用一個接一個在單一的方法。我在第一次呼叫中設定值爲accessToken
,並將其用於第二次請求。.ashx - 遠程服務器返回一個錯誤:(500)內部服務器錯誤
當我運行它,它給我的錯誤作爲
The remote server returned an error: (500) Internal Server Error.
以下是代碼。
HttpWebRequest webRequest = null;
HttpWebResponse webResponse = null;
Encoding encodingObj = null;
StreamReader streamReaderObj = null;
string grantCode = string.Empty;
string resultString = string.Empty;
string accessToken = string.Empty;
private void Instantiate()
{
grantCode = HttpContext.Current.Request.QueryString["code"].ToString();
webRequest = (HttpWebRequest)WebRequest.Create(Constants.ACCESS_TOKEN_REQUEST + "&code=" + grantCode);
webRequest.Method = "GET";
webRequest.ContentType = "application/json";
webResponse = (HttpWebResponse)webRequest.GetResponse();
encodingObj = System.Text.Encoding.GetEncoding("utf-8");
streamReaderObj = new StreamReader(webResponse.GetResponseStream(), encodingObj);
resultString = streamReaderObj.ReadToEnd();
JObject parameterCollection = JObject.Parse(resultString);
accessToken = parameterCollection["access_token"].ToString();
//HttpContext.Current.Response.Write("<br/><br/>Code: <br/>" + grantCode);
//HttpContext.Current.Response.Write("<br/><br/>Access Token: <br/>" + accessToken);
webRequest = (HttpWebRequest)WebRequest.Create(Constants.RETRIEVE_CONTEXT_REQUEST + "vista-688/id/Staff01");
webRequest.Method = "GET";
webRequest.Accept = "application/json";
webRequest.ContentType = "application/json";
webRequest.Headers.Add("Authorization", "Bearer " + accessToken);
webResponse = (HttpWebResponse)webRequest.GetResponse();
encodingObj = System.Text.Encoding.GetEncoding("utf-8");
streamReaderObj = new StreamReader(webResponse.GetResponseStream(), encodingObj);
resultString = streamReaderObj.ReadToEnd();
//HttpContext.Current.Response.Write("<br/><br/>Retrieve Context: <br/>" + resultString);
}
這些是從配置文件得到充分的休息API網址:
<add key="GrantCodeRequest" value="https://<location>/AuthorizationServices/provider/authorize?response_type=code&state=mystateid&client_id=mVisum&redirect_uri=http://localhost:1316/RetrieveContext.aspx&scope=read"/>
<add key="AccessTokenRequest" value="https://<location>/AuthorizationServices/oauth/token?client_id=mVisum&state=mystateid&scope=read&client_secret=TESTMVISUM&response_type=token&grant_type=authorization_code&redirect_uri=http://localhost:1316/RetrieveContext.aspx"/>
<add key="RetrieveContextRequest" value="http://<location>/UserContext/rest/context/user/system/"/>
當我做的只是用初始化爲有效值第二個呼叫accessToken
值第二請求也被工作沒有任何異常。這個方法寫在一個處理程序中。
任何人都可以告訴我爲什麼會發生這種情況嗎? REST Web服務中沒有問題。我還通過使用兩個單獨的網絡請求和網絡響應對象,但沒有什麼工作了
因此,*瀏覽器*顯示你500錯誤,但是你的代碼中發生了什麼異常?你是否嘗試過使用try/catch塊捕獲異常? –
調試時rservice的完整url是什麼? –
@Cory是的。它只是顯示相同的錯誤。沒有內在的例外。 – Ajinkya
