标签: webhttpbinding

在WCF中,有几种不同类型的基于HTTP的绑定:

• basicHttpBinding的
• WsHttpBinding的
• 的WebHttpBinding

这3个有什么不同？

特别是在功能/性能和兼容性方面有何不同？

我在使用HttpClient和BaseAddress属性调用webHttpBinding WCF端点时遇到问题.

HttpClient的

我创建了一个HttpClient实例,将BaseAddress属性指定为本地主机端点.

GetAsync Call

然后我调用GetAsync方法传递额外的Uri信息.

HttpResponseMessage response = await client.GetAsync(string.Format("/Layouts/{0}", machineInformation.LocalMachineName()));

服务端点

[OperationContract]
[WebGet(UriTemplate = "/Layouts/{machineAssetName}", ResponseFormat = WebMessageFormat.Json)]
List<LayoutsDto> GetLayouts(string machineAssetName);

问题

我遇到的问题是,是,/AndonService.svc所述BaseAddress的一部分被截断,从而将得到的呼叫转到https://localhost:44302/Layouts/1100-00277宁可https://localhost:44302/AndonService.svc/Layouts/1100-00277导致404未找到.

是否有理由在GetAsync调用中截断BaseAddress？我该如何解决这个问题？

我是WCF RESTFull服务开发的新手,我正在寻找一些有用的信息以及有关使用webHttpBinding的经验反馈,与新的WCF Web API http://wcf.codeplex.com/相比.

我正在寻找的是了解webHttpBinding的缺点,以及为什么要使用新的Web api,特别是新API解决的问题.如果你能指点我一些博客文章比较他们或只是谈论使用webHttpBinding时的问题我会很感激.先感谢您.

我已经为我的原型服务成功配置了3个端点.端点是basicHttpBinding,wsHttpBinding和webHttpBinding.我目前唯一的故障是WCFTestClient.当我将它指向我的服务时,它会列出前两个,但不会列出webHttpBinding.我可以通过浏览器测试REST端点,它工作得很好.这是我的配置:

我有两个WCF RESTful服务 - "通用"服务是公共的,没有安全性; "admin"服务我打算使用SSL进行基本身份验证.这是我的服务器端web.config:

        <endpointBehaviors>
            <behavior name="web">

            </behavior>
        </endpointBehaviors>

        <service name="MyNamespace.AppServices.GeneralService">

在客户端,我目前的代码如下所示:

我在Web上发现了很多关于将ASP.NET成员资格提供程序与wsHttpBindings一起使用的资料,但我没有看到任何与webHttpBindings一起使用它的参考资料.

我正在寻找一个可以在两种情况下工作的系统:

1. 用户登录到asp.net网站,该网站正在调用该服务.
2. 用户通过REST直接访问服务.

这可能是使用内置框架(即只是通过配置)？如果是这样,我该如何配置服务？用户如何将凭据传递给REST服务？

我正在尝试公开WCT REST服务,只有拥有有效用户名和密码的用户才能访问它.用户名和密码存储在SQL数据库中.

这是服务合同:

public interface IDataService
{
    [OperationContract]
    [WebGet(ResponseFormat = WebMessageFormat.Json)]
    byte[] GetData(double startTime, double endTime);
}

这是WCF配置:

<bindings>
  <webHttpBinding>
    <binding name="SecureBinding">
      <security mode="Transport">
        <transport clientCredentialType="Basic"/>
      </security>
    </binding>
  </webHttpBinding>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior name="DataServiceBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceCredentials>
        <userNameAuthentication
           userNamePasswordValidationMode="Custom"
           customUserNamePasswordValidatorType=
                 "CustomValidator, WCFHost" />
      </serviceCredentials>
    </behavior>
  </serviceBehaviors>
</behaviors>
<services>
  <service behaviorConfiguration="DataServiceBehavior" name="DataService">
    <endpoint address="" binding="webHttpBinding"
              bindingConfiguration="SecureBinding" contract="IDataService" />
  </service>
</services>

我通过Silverlight应用程序中的WebClient类访问该服务.但是,我无法弄清楚如何将用户凭据传递给服务.我为client.Credentials尝试了各种值,但它们似乎都没有在我的自定义验证器中触发代码.我收到以下错误:基础连接已关闭:发送时发生意外错误.

这是我尝试过的一些示例代码:

   WebClient client = new WebClient();
   client.Credentials = new NetworkCredential("name", "password", "domain");
   client.OpenReadCompleted += new OpenReadCompletedEventHandler(GetData);
   client.OpenReadAsync(new Uri(uriString));

如果我将安全模式设置为None,则整个过程都有效.我还尝试了其他clientCredentialType值,但没有一个工作.我还自行托管了WCF服务,以消除与IIS尝试在服务获得机会之前对用户进行身份验证相关的问题.

任何关于潜在问题的评论都会受到高度赞赏.谢谢. …

我现在已经调查了过去两小时的400-BadRequest代码.很多sugestions用于确保正确设置bindingConfiguration属性,在我的例子中,它是.

现在,在摧毁我所在的建筑物之前,我需要你的帮助:-)

我运行WCF RestFull服务(非常轻量级,使用此资源获取灵感:http://msdn.microsoft.com/en-us/magazine/dd315413.aspx),它(现在)接受通过提供的XmlElement(POX) POST动词.

在实现真正的客户端之前,我目前只使用Fiddler的请求构建器(因为这是混合环境).

当我为小于65K的XML执行此操作时,它工作正常 - 更大,它会抛出此异常:已超出传入消息的最大邮件大小配额(65536).要增加配额,请在相应的绑定元素上使用MaxReceivedMessageSize属性.

这是我的web.config文件(我甚至包括了客户端标签(绝望的时候!)):

    <httpRuntime maxRequestLength="1500000" executionTimeout="180"/>
  </system.web>

我正在编写一个有很多方法的Web服务.它们都设置类似于以下内容:

[OperationContract]
    [WebInvoke(
        BodyStyle = WebMessageBodyStyle.Bare,
        RequestFormat = WebMessageFormat.Json,
        ResponseFormat = WebMessageFormat.Json,
        UriTemplate = "x/y/z")]
    void someMethod(int x, int y, int z);

我想要做的只是在web.config文件中设置默认的BodyStyle/ RequestFormat/ ResponseFormatall.现在,我知道我可以这样做:

  <endpointBehaviors>
    <behavior name="webHttpBehavior">
      <webHttp defaultBodyStyle="Bare" defaultOutgoingResponseFormat="Json" />
    </behavior>
  </endpointBehaviors>

但似乎没有RequestFormat的属性.如何将默认设置RequestFormat为JSON？
