“远程服务器返回一个意外的响应：（400）错误的请求”

Question

我完全同意这个问题，我在moment.I有一直在阅读各种文章和博客的最后2天，使大多数的推荐变化，但我还是有这个问题难住了。

基本上我传递数组对象作为参数从客户机到该服务，然后给我的上述错误。

我可以处理200个记录确定，但如果我将它设置为250为例，它会返回400错误。我已经启用跟踪等，但没有被记录在所有的时候出现了错误。无论是客户端和服务都在相同的环境（测试）运行-windows 2008R2我会同时显示配置文件，以及如何我打电话的服务。

下面是我如何调用客户端这个服务...

List<FUMStruct> fList = new List<FUMStruct>();

for (int i = 0; i < 250; i++)
{
    var t = new FUMStruct();
    t.clientID = "1234";
    t.ClientCRMGUID = new Guid("9EACA7AE-FE7E-E211-956A-00505622E202");
    t.CRMAccountCRMGUID = new Guid("A63D9ADC-0CFF-E211-94E9-00505622E202");
    t.Balance = 200 + i;
    fList.Add(t);
}
var serv = new FinHqclientClient();            
serv.UpdateLastFUMGUID(fList.ToArray());

Answer 1

我注意到，你已经增加了你的客户的maxRequestLength的，但不是你的服务器：

  <system.web>
    <!-- ... -->
    <httpRuntime  executionTimeout="180" maxRequestLength="2147483647" />
  </system.web>

此配置选项是真的只为服务器相关，因为它设置入站请求的允许大小。在任何情况下，我想这部分添加到您的服务器配置文件，看看是否需要照顾的问题。默认请求大小为4MB，我从经验中知道这可能会导致您报告的错误。

Answer 2

这是因为当时在绑定一个“名称”值，。因此没有被应用于我们设置自定义值，并将其载入服务器的默认值（甚至不知道在哪里的“默认”为不同的绑定保持！）我发现了这一点由文章我读了网上，使新使用基本绑定only..which服务未能保持，直到我删除了名字，那么它开始工作！然后，我必须弄清楚如何，因为与绑定做它的wsHttpBinding，如果不指定名称（那么显然你不能引用配置），你会得到各种或安全问题等，并服务无法正常工作..所以解决办法是增加另一个结合没有它的名字属性。

只需要设置在中端服务器端，因为我离开了默认客户端的值（比在上面的例子中的那些更低），它仍然工作。以下是完整web.config..note我怎么过拖欠两个basicHttpBinding的和WsHttpBinding的
