XmlPullParserException 意外的标记位置：TEXT

Question

我在以下方法中遇到错误：

    public ResultUsers[] getContacts(java.lang.String user_id, java.lang.String offset, java.lang.String limit,
        java.lang.String phone_contacts) throws SoapFault {
    SoapObject _client = new SoapObject("urn:UserProfile", "GetContacts");
    _client.addProperty("user_id", user_id);
    _client.addProperty("offset", offset);
    _client.addProperty("limit", limit);
    _client.addProperty("phone_contacts", phone_contacts);
    SoapSerializationEnvelope _envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    _envelope.bodyOut = _client;
HttpTransportSE _ht = new HttpTransportSE(Configuration.getWsUrl()); // line 378
        try {
            _ht.call("urn:UserProfile#GetContacts", _envelope);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (XmlPullParserException e) {
            e.printStackTrace();
        }
        return ResultUsers.toArray((Vector<SoapObject>) _envelope.getResponse());
}

这是 logcat 的输出：

我在 google 上发现的是，在 resonse 的开头有 3 个字符，这通常是 android 中的解析器不知道的，这就是它崩溃的原因。但是我不确定如何摆脱这些字符，如果这是问题所在，考虑到我需要直接返回结果，我该如何解决。任何帮助将非常感激。

获取 WSDL 网址例如：http://abc.xyz/ws/User.wsdl

然后找到服务名；它可能会在页面的末尾。

例如：

<wsdl:service name="servicename">
        <wsdl:port name="userport" binding="tns:usrbinding">
            <soap:address
                location="http://abc.xyz/soap/ws/ServerWSDL.php" />
        </wsdl:port>
</wsdl:service>

该位置是您的主要网址；您必须将标头设置为该位置 url。一切都完成了。

注意：请勿更改soapAction URL。
