[MSCRM 2011]Javascript调用相关问题 RRS feed

  • 问题

  • 大家好,由于是初次接触MSCRM2011。我想问下如何调用如下一个解决方案中Web Resource中的方法,得到其中的whoamI Request中返回值userId,先谢谢了

    代码如下,

    if (typeof (SDK) == "undefined")
       { SDK = { __namespace: true }; }
           //This will establish a more unique namespace for functions in this library. This will reduce the
           // potential for functions to be overwritten due to a duplicate name when the library is loaded.
           SDK.new_Opp = {
               _getServerUrl: function () {
                   ///<summary>
                   /// Returns the URL for the SOAP endpoint using the context information available in the form
                   /// or HTML Web resource.
                   ///</summary>
                   var OrgServicePath = "/XRMServices/2011/Organization.svc/web";
                   var serverUrl = "";
                   if (typeof GetGlobalContext == "function") {
                       var context = GetGlobalContext();
                       serverUrl = context.getServerUrl();
                   }
                   else {
                       if (typeof Xrm.Page.context == "object") {
                             serverUrl = Xrm.Page.context.getServerUrl();
                       }
                       else
                       { throw new Error("Unable to access the server URL"); }
                       }
                      if (serverUrl.match(/\/$/)) {
                           serverUrl = serverUrl.substring(0, serverUrl.length - 1);
                       }
                       return serverUrl + OrgServicePath;
                   },
               LoginUserRequest: function () {
                   var requestMain = ""
                   requestMain += "<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\">";
                   requestMain += "  <s:Body>";
                   requestMain += "    <Execute xmlns=\"http://schemas.microsoft.com/xrm/2011/Contracts/Services\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">";

                   requestMain += "      </request>";
                   requestMain += "    </Execute>";
                   requestMain += "  </s:Body>";
                   requestMain += "</s:Envelope>";
                   var req = new XMLHttpRequest();
                   req.open("POST", SDK.new_Opp._getServerUrl(), true)
                   // Responses will return XML. It isn't possible to return JSON.
                   req.setRequestHeader("Accept", "application/xml, text/xml, */*");
