Dynamics CRM Web Api功能：使用encodeURIComponent時路徑中的非法字符

Question

我試圖通過Dynamics CRM 2016 Web API使用搜索功能（https://msdn.microsoft.com/en-us/library/mt608029.aspx）。這是我的代碼：

var start = new Date(2016, 2, 1, 17, 0, 0); 
var end = new Date(2016, 2, 10, 18, 0, 0); 

var request = new Object(); 
request.AppointmentRequest = new Object(); 
request.AppointmentRequest.SearchWindowStart = start.toISOString(); 
request.AppointmentRequest.SearchWindowEnd = end.toISOString(); 
request.AppointmentRequest.ServiceId = "5f3b6e7f-48c0-e511-80d7-d89d67631c44"; 
request.AppointmentRequest.Direction = 0; 
request.AppointmentRequest.NumberOfResults = 10; 
request.AppointmentRequest.UserTimeZone = 1; 

var req = new XMLHttpRequest() 
req.open("GET", clientUrl + "/api/data/v8.0/Search(" + encodeURIComponent(JSON.stringify(request)) +")", true); 
req.setRequestHeader("Accept", "application/json"); 
req.setRequestHeader("Content-Type", "application/json; charset=utf-8"); 
req.setRequestHeader("OData-MaxVersion", "4.0"); 
req.setRequestHeader("OData-Version", "4.0"); 
req.onreadystatechange = function() { 
    if (req.readyState == 4 && req.status == 200) { 
     alert(req.responseText); 
    } 
    else { 
     alert(req.response); 
    } 
}; 
req.send(); 

當我最初嘗試這種使用CRM在線我收到以下錯誤：

"An error has occurred.

Try this action again. If the problem continues, check the Microsoft Dynamics >CRM Community for solutions or contact your organization's Microsoft >Dynamics CRM Administrator. Finally, you can contact Microsoft Support."

當我嘗試這與現場部署與DevErrors =「開」 web.config中，我看到在事件查看器中出現以下錯誤：

Exception information: Exception type: HttpException Exception message: A potentially dangerous Request.Path value was detected >from the client (:). at System.Web.HttpRequest.ValidateInputIfRequiredByConfig() at System.Web.HttpApplication.PipelineStepManager.ValidateHelper(HttpContext >context)

Request information: Request URL: http://win-0e5dfqgqorm:444/ORG/api/data/v8.0/Search ({"AppointmentRequest":{"SearchWindowStart":"2016-03-01T17:00:00.000Z","SearchWindowEnd":"2016-03-10T18:00:00.000Z","ServiceId":"5f3b6e7f-48c0-e511-80d7-d89d67631c44","Direction":0,"NumberOfResults":10,"UserTimeZone":1}}) Request path: /SHUDEV/api/data/v8.0/Search({"AppointmentRequest":{"SearchWindowStart":"2016-03-01T17:00:00.000Z","SearchWindowEnd":"2016-03-10T18:00:00.000Z","ServiceId":"5f3b6e7f-48c0-e511-80d7-d89d67631c44","Direction":0,"NumberOfResults":10,"UserTimeZone":1}})

JSON對象進行編碼，所以我不知道爲什麼它檢測到非法字符。 Web Api的SDK文檔很簡單，並沒有涉及如何將ComplexType傳遞給Web Api函數的詳細信息，有沒有人在/將ManageType傳遞給Web Api函數之前看到過這個問題？

在此先感謝。

我設法解決了這個問題。關鍵是要通過JSON對象中作爲查詢參數：

var request = new Object(); 
request.SearchWindowStart = start.toISOString(); 
request.SearchWindowEnd = end.toISOString(); 
request.ServiceId = "5f3b6e7f-48c0-e511-80d7-d89d67631c44"; 
request.Direction = '0'; 
request.NumberOfResults = 10; 
request.UserTimeZoneCode = 1; 

var req = new XMLHttpRequest() 
req.open("GET", clientUrl + "/api/data/v8.0/Search(AppointmentRequest=@request)?@request=" + JSON.stringify(request) , true); 
req.setRequestHeader("Accept", "application/json"); 
req.setRequestHeader("Content-Type", "application/json; charset=utf-8"); 
req.setRequestHeader("OData-MaxVersion", "4.0"); 
req.setRequestHeader("OData-Version", "4.0"); 
req.onreadystatechange = function() { 
if (req.readyState == 4 && req.status == 200) { 
    alert(req.responseText); 
} 
else { 
    alert(req.response); 
    } 
}; 
req.send(); 

這是在SDK中記錄：https://msdn.microsoft.com/en-us/library/gg309638.aspx。

希望這可以幫助遇到類似問題的任何人。
