使用新的retrieveMultipleRecords（客户端API引用）从fetchXml获取结果

Question

var request = "<fetch output-format='xml-platform' distinct='true' version='1.0' mapping='logical'>" +
"<entity name='msdyn_incidenttype'>" +
"<attribute name='msdyn_name'/>" +
"<attribute name='createdon'/>" +
"<attribute name='msdyn_estimatedduration'/>" +
"<attribute name='msdyn_incidenttypeid'/>" +
"<order attribute='msdyn_name' descending='false'/>" +
"<link-entity name='product' link-type='inner' alias='ag' from='productid' to='aka_productfamilyid'>" +
"<link-entity name='msdyn_customerasset' link-type='inner' alias='ah' from='msdyn_product' to='productid'>" +
"<filter type='and'>" +
"<condition attribute='msdyn_customerassetid' operator='eq' uiname='' uitype='msdyn_customerasset' value='${custAssetId}'/>" +
"</filter>" +
"</link-entity>" +
"</link-entity>" +
"</entity>" +
"</fetch>";

我将上面的fetchXml与新的客户端api引用一起使用，如下所示：

var results = Xrm.WebApi.retrieveMultipleRecords("msdyn_incidenttype",request).then(
  function success(result) {
      for (var i = 0; i < result.entities.length; i++) {
          console.log(result.entities[i]);
      }
      console.log("Next page link: " + result.nextLink);
      // perform additional operations on retrieved records
  },
  function (error) {
      console.log(error.message);
      // handle error conditions
  }

我阅读的文档（https://docs.microsoft.com/en-us/dynamics365/customer-engagement/developer/clientapi/reference/xrm-webapi/retrievemultipleRecords）指出，第二个参数是options，如果是fetchXml（就像我现在使用的那样），则在其中指定它。然而，我在控制台中收到以下错误：

HTTP400:错误请求-由于语法无效，服务器无法处理请求。(XHR)get-https://dev.crm.dynamics.com/api/data/v9.0/msdyn_incidenttypes？fetch output-format='xml-platform'distinct='true'version='1.0'mapping='logic'>实体名称='msdyn_incidenttype'>属性名称='msdyn_incidenttype'>属性名称='msdyn_name'/>属性名称='msdyn_name'/>属性名称='msdyn_incidenttypeid'/>属性名称tid'to='aka_productfamilyid'>link-entity name='msdyn_customerasset'link-type='inner'alias='ah'from='msdyn_product'to='productid'>筛选器type='和'>条件attribute='msdyn_customerassetid'operator='eq'uiname='uitype='msdyn_customerasset'值='${custAssetId}

我是不是漏掉了什么？

您应该在前面添加“？fetchxml=”，如下所示：

Xrm.WebApi.retrieveMultipleRecords("msdyn_incidenttype", "?fetchXml= " + request).then(
                function success(result) {
                    return result;
                },
                function (error) {
                    console.log("failed with error: ", error);
                    return null;
                }
            );

选项
OData系统查询选项或FetchXML查询来检索数据。
