android - 如何使用 android 更新 Sharepoint 2010 列表项？

Question

我正在为 android 开发一个 sharepoint2010 应用程序。我想使用以下代码更新 Sharepoint 2010 ListItem:

private void updateListItem() {

    String serviceUrl = "http://IP_address/_vti_bin/Lists.asmx";
    HttpClient httpclient = new DefaultHttpClient();
    ((AbstractHttpClient) httpclient).getAuthSchemes().register("ntlm",
            new NTLMSchemeFactory());
    NTCredentials creds = new NTCredentials("username", "password", "55",
            "demo");
    ((AbstractHttpClient) httpclient).getCredentialsProvider()
            .setCredentials(AuthScope.ANY, creds);
    try {
        HttpConnectionParams.setConnectionTimeout(httpclient.getParams(),
                120000);

        HttpPost httppost = new HttpPost(serviceUrl);
        StringEntity se;            
        String str1 ="<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope      xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\"><soap:Body>"
                 + "<UpdateListItems xmlns=\"http://schemas.microsoft.com/sharepoint/soap/\">"
                 + "<listName>"
                 + "{DF1398C7-EF73-485E-913E-5F5896D6DF22}"
                 + "</listName>"
                 + "<updates>"
                 + "<Batch OnError='Continue' ListVersion='1'>"
                 + "<Method ID='1' Cmd='New'>"
                 + "<Field Name='Title'>View</Field>"
                 + "<Field Name='Resource'>7;#A Kr Singh</Field>"
                 + "<Field Name='Project'>13;#Microsoft- SharePoint based Employee Portal</Field>"
                 + "<Field Name='Task'>1;#Accounting</Field>"
                 + "<Field Name='Date'>2014-11-21 11:15:50</Field>"
                 + "</Method>"
                 + "</Batch>"
                 + "</updates>"
                 + "</UpdateListItems>"
                 + "</soap:Body>" + "</soap:Envelope>";
        se = new StringEntity(String.format(str1, HTTP.UTF_8));

        se.setContentType("text/xml");
        httppost.setEntity(se);

        HttpResponse httpresponse = httpclient.execute(httppost);
        InputStream in = httpresponse.getEntity().getContent();
        String str = inputStreamToString(in).toString();

        readSoap(str);

    } catch (Exception e) {

        e.printStackTrace();
    }
}

但是报错

soap:ServerException of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown.The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again.0x8102006d

请给我任何解决方案。
或者给我任何其他使用 android 更新 SharepointListItem 的方法。

嗨，经过一些重新教学，我在请求 header 中添加以下操作时找到了解决方案。

httppost.setHeader("SOAPAction", “http://schemas.microsoft.com/sharepoint/soap/UpdateListItems”)；之后工作正常。
