.net 发布某些数据时WCF错误400错误请求
我在本地机器上有一个WCF服务,它就像远程计算机中客户端应用程序和数据库之间的“桥梁” WCF服务与实体框架类一起工作,在获取数据时工作正常,但在发布任何内容和我收到下一条错误消息时不工作:“(400)错误请求” 这是我的客户代码:.net 发布某些数据时WCF错误400错误请求,.net,wcf,.net,Wcf,我在本地机器上有一个WCF服务,它就像远程计算机中客户端应用程序和数据库之间的“桥梁” WCF服务与实体框架类一起工作,在获取数据时工作正常,但在发布任何内容和我收到下一条错误消息时不工作:“(400)错误请求” 这是我的客户代码: //Connect to WCF Service CHS_Local.ServiceFrontalClient proxy = new CHS_Local.ServiceFrontalClient(); //Get a "Client" class wich Cl

void UpdateClient(Client editedClient);
在第一个例子中,我认为问题在于请愿书的权重,但我看到使用Fiddler发送请愿书的字节只有115.903字节(~0.11MB)。
有什么想法吗
如您所见,这是一个简单的示例,但不起作用:(
谢谢您的帮助!:)从客户端发布数据时,您必须在服务上设置
maxReceivedMessageSize
和readerQuotas
(如果需要)。您的客户端配置已修改了用于从服务获取数据的maxReceivedMessageSize
,但当您向服务发送大量数据时,您还必须修改其配置
比如:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="myBinding" maxReceivedMessageSize="500000" />
</wsHttpBinding>
</bindings>
<services>
<service name="CentralizedHostingService.ServiceFrontal">
<endpoint bindingConfiguration="myBinding" ... />
...
</service>
</services>
...
</system.serviceModel>
...

我在登台环境中也遇到了这个问题,因为我将通过线路发送更多字节
The remote server returned an unexpected response: (400) Bad Request. ---> System.Net.WebException: The remote server returned an error: (400) Bad Request.
下面是我在WCF web.config文件中所做的更改(在下面的配置中包括lessthen和greaterthen符号,因为标记不可见,所以无法添加)
发件人:
到
下面是上述绑定的端点地址标记
endpoint address="" binding="basicHttpBinding" bindingConfiguration="**ServiceBinding**"
经过上述改变后,它的工作就像魅力
谢谢,
M.Amalraj将您的服务交互放在此处我已经在客户端和服务器中更新了配置。但错误依然存在。
binding name="ServiceBinding" maxReceivedMessageSize="**262144**"
binding name="ServiceBinding" maxReceivedMessageSize="**2147483647**"
endpoint address="" binding="basicHttpBinding" bindingConfiguration="**ServiceBinding**"
