最近的一个项目中调用webservice接口,需要验证soapheader,现将解决方法记录如下:(网上资料出处太多,就不做引用,原作者如看到,如有必要添加请通知)
1、先看接口
POST /webserver/ValideWebService.asmx HTTP/1.1
Host: IP地址
Content-Type: text/xml; charset=utf-
Content-Length: length
SOAPAction: "http://命名空间/Login" <?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:Header>
<MySoapHeader xmlns="http://命名空间/">
<ProjectID>string</ProjectID>
</MySoapHeader>
</soap:Header>
<soap:Body>
<Login xmlns="http://命名空间/">
<loginName>string</loginName>
<passowrd>string</passowrd>
</Login>
</soap:Body>
</soap:Envelope>
验证时需要验证header和body两部分,需要引入第三方jar包,ksoap2-android-assembly-2.5.2-jar-with-dependencies.jar。下面就是我验证使用的方法,网上有许多,只不过无法验证,“拿来”修改一下,做个记录,供以后查看,也方便大家参阅。
先声明以下;
//命名空间
private static final String NAMESPACE = "http://命名空间/";
//服务地址
private static String URL = "http://IP地址或者域名/webserver/ValideWebService.asmx";
//调用的方法名
private static final String METHOD_NAME = "Login";
//此处是命名空间+方法名
private static String SOAP_ACTION = "http://命名空间/Login";
private SoapObject detail;
由于2.3以上无法在主线程中直接访问网络,所以在需要的地方开启一个子线程,这里我在点击按钮登录的时候需要,因此写在onclick()方法下:
new Thread() {
@Override
public void run() {
// TODO Auto-generated method stub
super.run();
try {
SoapObject rpc = new SoapObject(NAMESPACE, METHOD_NAME);
//此处2个propertyinfo,是Login方法所需的参数,代码下面贴出asmx代码
PropertyInfo pi = new PropertyInfo();
pi.setName("loginName");
pi.setValue(cardNumStr);
rpc.addProperty(pi);
pi=new PropertyInfo();
pi.setName("passowrd");
pi.setValue(passwordStr);
rpc.addProperty(pi);
//soapheader在这里
Element[] header = new Element[1];
header[0] = new Element().createElement(NAMESPACE, "MySoapHeader");
Element username = new Element().createElement(NAMESPACE, "ProjectID");
username.addChild(Node.TEXT, "这里是值");
header[0].addChild(Node.ELEMENT, username);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.headerOut = header;
envelope.bodyOut = rpc;
envelope.dotNet = true;
envelope.setOutputSoapObject(rpc);
HttpTransportSE ht = new HttpTransportSE(URL);
ht.call(SOAP_ACTION, envelope);
//SoapObject
detail =(SoapObject) envelope.getResponse();
System.out.println("返回的结果"+ detail.toString());
}catch (Exception e){
System.out.println("错误消息:"+ e.getMessage());
}
Message msg = handler.obtainMessage();
msg.obj=detail;
handler.sendMessage(msg);
}
}.start();
上面的cardNumStr和passwordStr是我从文本输入框获取的值。访问网络从接口通过验证然后获得返回值,对返回的数据进行处理就可以了。
用SoapObject,要不返回的detail为null。
private Handler handler = new Handler() {
public void handleMessage(Message msg) {
//这里做你的UI处理
};
};
