java - 奇怪的 httpPost 行为(可能与 json、auth、代理相关)GET 有效，POST 有效，但没有代理就不行(部分解决)

Question

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，还可以从 .NET 4.0 应用程序)成功访问该服务

基本上，我在 Android Activity 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 应用程序时，我注意到我无法执行 PUT 操作(GET 工作正常)。他们返回错误 400 - 错误请求由于它在 js 上运行正常，我使用 fiddler2 来看看发生了什么。当我设置模拟器通过 fiddler 代理工作时，请求突然变得正常。然后我在没有代理的情况下再次尝试，它返回错误 400。我还尝试将 apk 上传到我的 Galaxy S 并通过网络连接。同样，GET 有效，但 PUT 无效...

有什么想法吗？

由于与协议(protocol)相关的问题，我开始在服务器中测试多种认证方案。似乎自 2008 年以来，java 和 apache 都不支持在新服务器中实现的新 NTLMv2。

我发现(并丢失了)一个网站，其中指出使用 JCIFS 来带来差距。但事情并不是包含jar那么简单，还必须写一部分代码，而所有的支持都是不确定的，不能保证的。用实际行话来说，这意味着“仅使用基本身份验证”，但使用大写字母......

顺便说一句，我找到了它的工作方式。只需添加以下内容:

httpClient.getParams().setBooleanParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, false);

戴夫，我欠你一个大人情!非常感谢大家阅读该帖子!
