我在ASP .Net 4.0中有一个标准的web服务，定义如下：
[WebMethod]
public string MyWebServiceRequest(string data)
{
//Code
}
字符串的大小约为10K字节，当尝试发送到此Web服务时，我收到400 Bad Request。如果我只发几行就可以了。
据我所知，默认最大大小约为65KB，或者我错了？我在事件查看器中没有出现错误，等等。有没有办法强制记录Web服务的错误？
更新： 如果这可能导致我的问题，是否有任何限制允许你在字符串中使用？
以下是我要求发送的实际数据的请求。就像一个笔记我已经设法通过删除其中一行来发送它，我不明白为什么这一行会使请求失败。

web.config中有一个控制最大传输大小的部分：

但我怀疑这是你真正的问题。您是否尝试在Fiddler中检查请求以确保您的网页确实发送了正确的数据？ 400错误可能意味着任何数量的事情，包括发布到一个畸形的URL（即https而不是http，错误的主机头等）。
<强>注释
虽然我在这，但为什么你这样使用XML信封？如果您要经历使用XML / SOAP的麻烦，为什么不传递更好的，XML友好的数据集（带子节点等）？
