CRM Dynamics调用WCF服务错误
本文关键字:服务 错误 WCF 调用 Dynamics CRM | 更新日期: 2023-09-27 18:24:01
嗨,我有一个CRM 2013插件,它调用WCF服务,该服务失败并出现以下错误:
'通信对象,System.ServiceModel.ChannelFactory `1[ISupplyClaimsService],不能为在打开状态下修改’,
我有时也会发现,当调用该服务时,插件注册工具会崩溃。是否可以从插件调用WCF服务?我在网上看到了一些帖子,但没有具体的工作解决方案,甚至在CRM SDK中也没有。我的CRM是内部部署2013,插件是在Sandbox隔离(NONE)之外注册的,WCF服务使用命名域而不是IP地址,它通过HTTP协议运行,请参阅下面的代码。我已经满足了关于插件和外部系统的所有要求,但仍然没有运气。我还在控制台应用程序中测试了该服务,SOAP UI运行良好,只是在插件中我遇到了问题。
public void Execute(IServiceProvider serviceProvider)
{
ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
if (context == null)
{
throw new ArgumentNullException("loaclContext");
}
if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
{
Entity supplyClaimsEntity = (Entity)context.InputParameters["Target"];
if (supplyClaimsEntity.LogicalName != "new_supplierclaimsupdate")
{
return;
}
IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
IOrganizationService service = serviceFactory.CreateOrganizationService(context.InitiatingUserId);
string entityBeginUpload = "Start Upload";
try
{
BasicHttpBinding myBinding = new BasicHttpBinding();
myBinding.Name = "BasicHttpBinding_ISupplyClaimsService";
myBinding.Security.Mode = BasicHttpSecurityMode.None;
myBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
myBinding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
myBinding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
EndpointAddress endPointAddress = new EndpointAddress(@"http://wmvapps01.tarsus.co.za/SupplyClaimsService.svc");
ChannelFactory<ISupplyClaimsService> factory = new ChannelFactory<ISupplyClaimsService>(myBinding, endPointAddress);
ISupplyClaimsService channel = factory.CreateChannel();
channel.StartApplication();
factory.Close();
}
我有一个具有Rest method
的WCF Rest WebService
。WebService代码:
public interface ICRMRestWebService
{
[OperationContract]
[WebInvoke(Method = "POST",
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json,
BodyStyle = WebMessageBodyStyle.WrappedRequest,
UriTemplate = "GetLatestContractByContactIdRestMethod")]
LatestMembershipResponse GetLatestContractByContactIdRestMethod(string contactId, AuthenticateRequest authenticateRequest);
}
WCF Rest WebService is
:的Web.config
<system.serviceModel>
<services>
<service name="GRID.CRM.WebServices.CRMRestWebService.CRMRestWebService" behaviorConfiguration="ServiceBehaviour">
<endpoint address="" binding="webHttpBinding" contract="GRID.CRM.WebServices.CRMRestWebService.ICRMRestWebService" behaviorConfiguration="web">
</endpoint>
</service>
</services>
<bindings />
<client />
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehaviour">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="web">
<webHttp/>
</behavior>
</endpointBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" />
我从CRM Plugin
调用这个方法,如下所示:
public void Execute(IServiceProvider serviceProvider)
{
IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
IOrganizationServiceFactory serviceFactory;
IOrganizationService service;
if (context.Depth > 1)
return;
if (context.InputParameters.Contains("Target"))
{
//Create Service from Service Factory
serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
service = serviceFactory.CreateOrganizationService(context.UserId);
var javaScriptSerializer = new JavaScriptSerializer();
javaScriptSerializer.MaxJsonLength = 104857600; //200 MB unicode
StringBuilder URI = new StringBuilder();
URI.Append(crmRestWebServiceUrl).Append(webServiceMethod);
//Logger.Info("GetLatestMembershipFromCRMRestWebService is called with Url: " + URI.ToString());
var request = (HttpWebRequest)WebRequest.Create(URI.ToString());
request.Method = "POST";
request.Accept = "application/json";
request.ContentType = "application/json; charset=utf-8";
//Serialize request object as JSON and write to request body
if (latestMembershipRequest != null)
{
var stringBuilder = new StringBuilder();
javaScriptSerializer.Serialize(latestMembershipRequest, stringBuilder);
var requestBody = stringBuilder.ToString();
request.ContentLength = requestBody.Length;
var streamWriter = new StreamWriter(request.GetRequestStream(), System.Text.Encoding.ASCII);
streamWriter.Write(requestBody);
streamWriter.Close();
// Logger.Info("Request Object that will be sent is: " + stringBuilder.ToString());
}
// Logger.Info("Sending Request to CRMRestWebService to get LatestMembership.");
var response = request.GetResponse();
//Read JSON response stream and deserialize
var streamReader = new System.IO.StreamReader(response.GetResponseStream());
var responseContent = streamReader.ReadToEnd().Trim();
LatestMembershipResponse latestMembershipResponse = javaScriptSerializer.Deserialize<LatestMembershipResponse>(responseContent);
// Logger.Info("Latest Membership Reveived is: " + responseContent.ToString() + " has been deserialized Successfully.");
return latestMembershipResponse;
}
