android - android 中使用 SoapPrimitive 的 ksoap（Web 服务）示例

Question

1. 此代码没有给我任何错误或警告，但无法正常工作，我不知道问题出在哪里，请帮助我。

   package com.example.webtest;

Answer 1

你为什么使用 SoapPrimitive？首先，检查您的响应是否为错误。否则，通过调用 response.bodyIn 从响应对象中获取响应体：

SoapObject response = null;
if (envelope.bodyIn instanceof SoapObject) { // SoapObject = SUCCESS
    response = (SoapObject) envelope.bodyIn;
} else if (envelope.bodyIn instanceof SoapFault) { // SoapFault =
                                                    // FAILURE
    SoapFault soapFault = (SoapFault) envelope.bodyIn;
    throw new Exception(soapFault.getMessage());
}

然后，您可以通过调用 response.getProperty("responsecode") 从响应中获取属性。

此外，在调试时将 HttpTransportSE 的调试值设置为 true：

transportSE.debug = true;
