我编写了一个REST WCF RIA Silverlight 4.0兼容服务，我可以从javascript + jQuery.1.4.2.js + JSON2.js（当然还有.NET 4.0应用程序）中成功访问
基本上，我在Android活动中所做的是：
HttpPost request = new HttpPost(SERVICE_URI + "/SubmitChanges");
request.setHeader("Accept", "application/json; charset=utf-8");
request.setHeader("Content-type", "application/json; charset=utf-8");
// Build JSON string
JSONStringer myTable = new JSONStringer()
.object()
.key("changeSet")
.array()
.object()
.key("Id").value(0)
.key("Entity")
.object()
.key("__type").value("MyTable:#MyServiceApp.Web")
.key("ID").value(21)
.endObject()
.key("Operation").value(4)
.endObject()
.endArray()
.endObject();
Log.d("WebInvoke", "MyTable : " + myTable.toString());
StringEntity entity = new StringEntity(myTable.toString());
// entity.setContentType("application/json; charset=utf-8");
// entity.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json; charset=utf-8"));
request.setEntity(entity);
Log.d("WebInvoke", "Entity : " + entity.toString());
// Send request to WCF service
DefaultHttpClient httpClient = new DefaultHttpClient();
httpClient.getCredentialsProvider().setCredentials(new AuthScope(null,-1), new UsernamePasswordCredentials("myuser","mypassword"));
// HttpClientParams myParam = (HttpClientParams) httpClient.getParams();
// Log.d("WebInvoke", "Entity : " + myParam.toString());
HttpResponse response = httpClient.execute(request);
当转向Android应用时，我注意到我不能做PUT的操作（GET工作正常）。他们返回错误400 - 错误的请求 由于它在js上工作正常，我使用fiddler2来查看发生了什么。当我设置模拟器来完成fiddler代理时，突然，请求已经变好了。然后我再次尝试没有代理，它返回错误400.我尝试上传apk到我的Galaxy S并通过网络连接。同样，GET可行，但PUT不会......
有什么想法吗？
Saludos，OSCAR。

作为与协议相关的问题，我开始测试服务器中的多样化身份验证方案。似乎自2008年以来，java和apache都支持在新服务器中实现的新NTLMv2。
我发现（并丢失）一个网站，注意到使用JCIFS来弥补差距。但是包含jar的东西并不是那么简单，你还必须编写部分代码，并支持所有不确定但不会被忽略的代码。这意味着，在实际的术语中，“仅使用基本身份验证”，但以大写字母表示......
顺便说一句，我找到了它的工作方式。它只是添加了这个：httpClient.getParams().setBooleanParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, false);

您是否尝试在charset上明确设置StringEntity？
import org.apache.http.protocol.HTTP;
...
StringEntity entity = new StringEntity(myTable.toString(),HTTP.UTF_8);

对于任何引用此问题的人（在被问到大约一年后），我遇到了几乎相同代码的类似问题。问题似乎与setCredentials()方法有关。显然，它包含一些GET很好的空格但导致PUT或POST出现问题。
手动设置授权可以解决问题。类似的东西：
request.setHeader("Authorization","Basic "+Base64.encodeToString("login:password".getBytes(),Base64.URL_SAFE|Base64.NO_WRAP););
请记住使用Base64.URL_SAFE | Base64.NO_WRAP。
