Dynamics CRM Web Api 功能：使用 encodeURIComponent 时路径中存在非法字符

Question

我正在尝试通过 Dynamics CRM 2016 Web API 使用搜索功能 (https://msdn.microsoft.com/en-us/library/mt608029.aspx)。这是我的代码：

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();

当我最初使用 CRM Online 尝试此操作时，我收到以下错误：

"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."

当我在 web.config 中使用 DevErrors="On" 的内部部署尝试此操作时，我在事件查看器中看到以下错误：

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 对象已编码，所以我不确定为什么会检测到非法字符。 Web Api 的 SDK 文档很简单，没有详细介绍如何将 ComplexType 传递给 Web Api 函数，有没有人看到这个问题 before/managed将 ComplexType 传递给 Web Api 函数？

提前致谢。

我设法解决了这个问题。关键是将JSON对象作为查询参数传入：

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();

这在 SDK 中有记录：https://msdn.microsoft.com/en-us/library/gg309638.aspx。

希望这对遇到类似问题的任何人有所帮助。
