使用 ksoap2-android 订阅共享点 Web 服务时出现身份验证错误

我正在编写一个Android应用程序，它将使用sharepoint 2010中lists.amx服务的getlist()方法。我正在使用kso​​ap2-android来处理我的soap消息。当我尝试进行身份验证时，出现预期的 xmlpullparser 异常 START_TAG... 为什么以下代码无法通过共享点服务器的身份验证？

这是我的代码：

public class SharepointList extends Activity {
private static final String SOAP_ACTION = "http://schemas.microsoft.com/sharepoint/soap/GetList";
private static final String METHOD_NAME = "GetList";
private static final String NAMESPACE = "http://schemas.microsoft.com/sharepoint/soap/" ;
private static final String URL = "http://<ip of sharepoint server>/_vti_bin/lists.asmx";

private TextView result;
private Button btnSubmit;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    result = (TextView)findViewById(R.id.textView1);
    btnSubmit = (Button)findViewById(R.id.button1);
    btnSubmit.setOnClickListener(new OnClickListener(){
        public void onClick(View v) {
            if(v.getId() == R.id.button1)
            {
                String list = getMobileTestList();
                result.setText(list);
            }

        }

    });


}
private String getMobileTestList()
{
    PropertyInfo pi = new PropertyInfo();
    pi.setName("listName");
    pi.setValue("Mobile Test List");

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    request.addProperty(pi);

    String authentication = android.util.Base64.encodeToString("username:password".getBytes(), android.util.Base64.DEFAULT);
    List<HeaderProperty> headers = new ArrayList<HeaderProperty>();
    headers.add(new HeaderProperty("Authorization","Basic " +authentication));
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);


    HttpTransportSE transport = new HttpTransportSE(URL);
    try
    {
        transport.debug = true;
        transport.call(SOAP_ACTION, envelope, headers);
        //transport.call(SOAP_ACTION, envelope);
        Object result = envelope.getResponse();
        return result.toString();

    }
    catch(Exception e)
    {
        return e.toString();
    }
}
}

这是 Transport.request 转储（前面的“

• v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://schemas.xmlsoap.org/soap/encoding/" xmlns:v="http://schemas.xmlsoap.org/soap/envelope/">
  • v:标题/>
  • v:Body>
    • GetList xmlns="http://schemas.microsoft.com/sharepoint/soap/" id="o0" c:root="1">
      • listName i:type="d:string">移动测试列表
  • /获取列表>
  • /v:正文>
• /v:信封>

这是 Transport.response 转储（前面的“

• !DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd">
  • HTML>
  • HEAD>

    • h2>错误请求 - 无效主机名
    • hr> p>HTTP 错误 400。请求主机名无效。

也许可以尝试以下方法：

String authentication = android.util.Base64.encodeToString("username:password".getBytes(), android.util.Base64.NO_WRAP);

默认情况下，Android Base64 util 将换行符添加到编码字符串的末尾。这会使 HTTP 标头无效并导致“错误请求”。

The Base64.NO_WRAPflag 可以防止这种情况发生并保持标头完好无损。
