【问题描述】：
我正在编写 WCF WebService 来处理我的 Android 项目。我有一个名为 CreateOrder 的方法，一切正常，直到我注意到如果我发送的 XML 数据文件太大，我会遇到异常：
06-28 15:23:09.894: E/Błąd wątku mainThread / Sender(6988): java.io.IOException: HTTP request failed, HTTP status: 500
然后我将我的 Android 项目库从“ksoap2-android-assembly-3.0.0-jar-with-dependencies”更改为“ksoap2-android-assembly-3.0.0-RC.4-jar-with-dependencies” " 这就是错误现在的样子：
06-28 15:18:47.124: E/Błąd wątku mainThread / Sender(6623): SoapFault - faultcode: 'a:DeserializationFailed' faultstring: '格式化程序在尝试反序列化消息时抛出异常：错误 反序列化操作“CreateOrder”的请求消息正文。这 已超出最大字符串内容长度配额 (8192)，而 读取 XML 数据。这个配额可以通过改变 XmlDictionaryReaderQuotas 上的 MaxStringContentLength 属性 创建 XML 阅读器时使用的对象。第 257 行，第 38 位。 faultactor：'null' 详细信息：null
在我认识到发生了什么之后，我更改了配额的大小等。我正在处理这个问题，因为 2 天找不到解决方案。也许你们中的一些人发现我的 WCF / Config 有问题。我也过去了 Android / LogCat 的方法，但我认为这是 WCF 问题。
这是我的 WCF / App.config

这是否是解决方案我只是建议你良好的编程习惯：你为什么不尝试 AsyncTask 来访问服务器？？
-
首先确保 wcf 客户端可以使用此服务。然后将工作 wcf 客户端的请求与 android 的请求进行比较
