演练：与 JavaScript 结合使用现代应用程序 SOAP 终结点

2017-07-06

发布日期： 2016年11月

适用于： Dynamics CRM 2015

本演练演示如何创建用于 Web 资源的 SOAP 终结点的 JavaScript 库。目前，Microsoft Dynamics CRM 2015 和 Microsoft Dynamics CRM Online 2015 更新不提供可用来通过 SOAP 终结点调用可用消息的 JavaScript 库。本演练演示如何为使用组织服务 Execute 方法的 Assign 消息创建 JScript 库。使用 Execute 方法的其他任何消息都将遵循类似模式。为任何消息创建 JavaScript 库都需要类似的过程。有关使用此过程开发的 JavaScript 库的示例，请参阅示例：使用 JavaScript 检索实体元数据。

备注

有关使用 SOAP 终结点的完整示例 JavaScript 库，请参阅 Sdk.Soap.js 库。使用此处所述步骤创建的 Sdk.Soap.js 库。

该过程包括捕获从托管代码控制台应用程序发送的 HTTP 请求和响应，然后创建一个 JavaScript 库，其中包含用于发送相同请求和处理相似响应的函数。通常使用 Fiddler 等应用程序捕获 HTTP 请求和响应，但 Fiddler 和类似的应用程序无法捕获用于内部部署 Microsoft Dynamics CRM 2015 的加密 HTTP 流量。提供的 SOAPLogger 解决方案示例捕获加密前的 HTTP 请求和解密后的 HTTP 响应。SOAPLogger 示例解决方案同时适用于 Microsoft Dynamics CRM 2015 和 Microsoft Dynamics CRM Online 2015 更新。SOAPLogger 还会筛选掉与创建 JScript 库的任务无关的任何 HTTP 流量。

本演练将指导您完成以下任务：

在捕获示例 HTTP 请求和响应中，您将编辑 SOAPLogger 示例的 Run 方法，以使用托管代码执行 Assign 请求。
然后，您将运行 SOAPLogger 解决方案，以生成有关发送的 HTTP 请求和接收的响应的信息。
在创建 JScript 库中，您将根据捕获的 HTTP 流量创建一个 JScript 库，以使用组织服务 Execute 方法发送和接收 Assign 消息。
在测试 JScript 库中，您将测试 JScript 库，以确认它是否可用于分派记录。
在创建交互式 Web 资源中，您将创建一个 HTML Web 资源，它使用该库来为选定用户分派 Account 记录，如下面的屏幕截图所示。

表示已完成演练的托管解决方案可在 SDK 包中的以下位置获取：SDK\SampleCode\JS\SOAPForJScript\SOAPEndpointforJScript_1_0_0_1_managed.zip。下载 Microsoft Dynamics CRM SDK 包。您可以安装（导入）此解决方案并查看完整结果。由于这是一个托管解决方案，因此可以轻松卸载（删除）它，以将其从系统中彻底移除。

SDK\SampleCode\JS\SOAPForJScript\SOAPForJScript.sln 是一个 Visual Studio 解决方案，其中包含具有本演练中代码的 HTML 和 JS 文件。

必备项

您还必须能够编写与要使用 JScript 执行的函数对应的托管代码。
您需要访问位于 SOAPLogger 的 SDK 下载文件中提供的 SDK\SampleCode\CS\Client\SOAPLogger 示例。

备注

Microsoft Dynamics CRM SDK 中的 SOAPLogger 示例仅适用于 Microsoft Visual C#。如果您选择 Microsoft Visual Basic .NET 版本，请参阅 CodePlex 上的 Microsoft Dynamics CRM VB.Net SoapLogger。
您需要 Microsoft Visual Studio 来运行 SOAPLogger 解决方案。
您需要具备使用 XMLHttpRequest 进行 JScript 和异步编程的丰富知识。

捕获示例 HTTP 请求和响应

编辑 SOAPLogger 解决方案，以添加使用 AssignRequest 执行 SoapLoggerOrganizationService 的代码。SoapLoggerOrganizationService 继承自 IOrganizationService 并增加了生成日志文件的功能，该日志文件显示发送和接收到的相关 HTTP 流量。

使用 Microsoft Visual Studio 打开位于 SOAPLogger 的 SDK\SampleCode\CS\Client\SOAPLogger\SOAPLogger.sln 解决方案。

在 SoapLogger.cs 文件中，找到以下示例中显示的 Run 方法：


public void Run(ServerConnection.Configuration serverConfig)
{
 try
 {

  // Connect to the Organization service. 
  // The using statement assures that the service proxy will be properly disposed.
     using (_serviceProxy = new OrganizationServiceProxy(serverConfig.OrganizationUri, serverConfig.HomeRealmUri, serverConfig.Credentials, serverConfig.DeviceCredentials))
  {
   // This statement is required to enable early-bound type support.
   _serviceProxy.EnableProxyTypes();

   IOrganizationService service = (IOrganizationService)_serviceProxy;


   using (StreamWriter output = new StreamWriter("output.txt"))
   {

    SoapLoggerOrganizationService slos = new SoapLoggerOrganizationService(serverConfig.OrganizationUri, service, output);

    //Add the code you want to test here:
    // You must use the SoapLoggerOrganizationService 'slos' proxy rather than the IOrganizationService proxy you would normally use.



   }


  }

 }

 // Catch any service fault exceptions that Microsoft Dynamics CRM throws.
 catch (FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault>)
 {
  // You can handle an exception here or pass it back to the calling method.
  throw;
 }
}

标识 SystemUser 记录的有效 ID，以及未分派给该用户的 Account 记录的 ID。

提示

若要从应用程序的所有记录中获取 Id，打开该记录并使用“复制链接”命令。将该链接粘贴到记事本中并隔离包含 id 参数值（不包括编码的括号 (“%7b” = “{”) 和 (“%7d” = “}”)）的部分。例如，下面的内容表示 Account 记录的 URL。<your organization root url>/main.aspx?etc=1&id=%7bF2CA52DE-552D-E011-A8FB-00155DB059BE%7d&pagetype=entityrecord>。 ID 值为 F2CA52DE-552D-E011-A8FB-00155DB059BE。

使用这些值替换以下代码中的占位符值，并将代码添加到所指示的运行方法中。有关分派请求的详细信息，请参阅AssignRequest。
```
Guid userId = new Guid("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX");
Guid accountId = new Guid("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX");
AssignRequest assign = new AssignRequest{Assignee = new EntityReference(SystemUser.EntityLogicalName, userId),Target = new EntityReference(Account.EntityLogicalName, accountId)};
AssignResponse assignResp = (AssignResponse)slos.Execute(assign);
```
按 F5 调试应用程序。输入有关服务器的信息和您的身份验证凭据。如果代码运行成功，则会立即将客户记录分派给您指定的用户。有关运行示例示例的详细信息，请参阅使用 Microsoft Dynamics CRM 2015 Web 服务运行简单程序
在 SOAPLogger 项目文件夹中，导航到 bin 和 Debug 文件夹并查找 output.txt 文件。

打开 output.txt 文件并查看内容。内容应如下所示，但实际 GUID 值将替换占位符“XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX””。

请注意使用代码传入的变量的位置，包括 Account 实体的逻辑名称。

您已成功捕获 HTTP 流量中执行分派操作的相关部分。

创建 JScript 库

库的具体构造方式由您自己决定。每个 JScript 应包含以下元素：

用于确保任何函数名称都唯一的策略。
用于检索指向 Web 资源的 SOAP 终结点的 URL 的方法。
用于异步发送请求和接收响应的不同方法。
用于处理返回的任何 WCF 错误的函数。

下面的 JScript 库包含这些元素以及 assignRequest 和 assignResponse 函数，以基于使用 SOAPLogger 捕获的 HTTP 请求和响应来使用 Assign 消息。

测试 JScript 库

在准备好 JScript 库之后，应执行一些初始测试，以确认该库能否正常工作。由于身份验证只在应用程序内进行，因此必须使用库内容在 Microsoft Dynamics CRM 2015 中创建脚本 Web 资源。为了使用库中的函数，需要某个 UI 元素（窗体或 HTML Web 资源）来调用库中的 JScript 函数。下面的过程介绍如何使用简单的 HTML Web 资源来测试库中的函数。

使用以下代码创建一个 HTML 文档：


<html xmlns="http://www.w3.org/1999/xhtml">

  var usersToShow = 10;
  var users = [];
  var accounts = [];

  document.onreadystatechange = function () {
   ///<summary>
   /// Initializes the sample when the document is ready
   ///</summary>
   if (document.readyState == "complete") {
    userid = document.getElementById("userid");
    accountid = document.getElementById("accountid");
    resultsArea = document.getElementById("results");
    userLookup = document.getElementById("userLookup");
    accountLookup = document.getElementById("accountLookup");

    populateUserLookup();
    populateAccountLookup();

   }
  }

使用该代码创建一个 HTML Web 资源。该 HTML Web 资源的全名将取决于您的解决方案的自定义前缀。假定您的解决方案自定义前缀为“new”，则将该 HTML Web 资源命名为“new_/AssignTest.htm”。只要所有 Web 资源使用同一自定义前缀，那么使用的特定自定义前缀将对此示例没有任何影响。
使用 JScript 库的内容创建脚本 Web 资源。将该 Web 资源命名为“new_/Scripts/SDK.SOAPSample.Assign.js”。
发布所有自定义设置并打开 new_/AssignTest.htm Web 资源。单击“预览”按钮。
使用No text is specified for bookmark or legacy link 'c9a435ab-a4cb-4e0c-9ef7-b7ba66278407#BKMK_EditSoapLogger'.过程的步骤 3 中所用的同一过程标识有效的系统用户和客户记录 Id 值，并将其粘贴到该页。然后单击Test Assign确认可获得成功响应。

输入无效值，以确认能够正确分析错误。

例如，如果输入“A Store (sample)”而不是客户的 Id，应显示以下错误消息：

The formatter threw an exception while trying to deserialize the message: 
There was an error while trying to deserialize parameter https://schemas.microsoft.com/xrm/2011/Contracts/Services:request. 
The InnerException message was 'There was an error deserializing the object of type Microsoft.Xrm.Sdk.OrganizationRequest. 
The value 'A Store (sample)' cannot be parsed as the type 'Guid'.'.  Please see InnerException for more details.

如果 AccountId 没有对应的客户记录，则您会看到以下消息：

Account With Id = 883c3084-1f2f-e011-ad66-00155dba3814 Does Not Exist

创建交互式 Web 资源

下一步是在窗体脚本、功能区命令或 Web 资源中使用 JScript 库。下面的示例代码表示一个 HTML Web 资源，它使用 REST 终结点检索 SystemUser 和 Account 记录的列表，以提供为用户分派客户记录的交互式用户界面。此页通过 Scripts/SDK.SOAPSample.Assign.js 脚本 Web 资源和使用 json2.js 库的脚本 Web 资源来支持将 JSON 对象用于 REST 终结点。SDK.REST.js 库用于检索使用 REST 终结点的数据。
