手动SOAP Call WebService

前不久公司接了个活，要求在Pnuts中Call WebService，本来是一件很容易的事，可不能添加第三方的类包给我造成了麻烦。不能使用Ajax等一些第三方的包，意味着我只能自己去解析SOAP协议，而在PNuts中虽然可以调JAVA的方法，但却不适合写很大的功能，最后采用了一种非常傻的做法，手动去拼SOAP消息的内容，写在这作为对一些特殊需求的一种实现方式：

try {

postStr = postStr + " <?xml version='1.0' encoding='utf-8'?> " ;

postStr = postStr + " <soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' " ;

postStr = postStr + " xmlns:xsd='http://www.w3.org/2001/XMLSchema' " ;

postStr = postStr + " xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'> " ;

postStr = postStr + " <soap:Body> " ;

postStr = postStr + " <exchangeData xmlns='https://www.riverbed.com/mfg/DataExchange/'> " ;

postStr = postStr + " <sender>Test</sender> " ;

postStr = postStr + " <password>35b82957-c792-81ce-38e4-7c83ad3291ea</password> " ;

postStr = postStr + " <transactionType>Test_Get_Data</transactionType> " ;

postStr = postStr + " <data> " ;

postStr = postStr + htmlEncode(data);

postStr = postStr + " </data> " ;

postStr = postStr + " </exchangeData> " ;

postStr = postStr + " </soap:Body> " ;

postStr = postStr + " </soap:Envelope> " ;

URL url = new URL( " https://www.test.com/testdata.php " );

HttpURLConnection conn = (HttpURLConnection)url.openConnection();

conn.setDoOutput( true );

conn.setRequestMethod( " POST " );

conn.setRequestProperty( " Content-Type " , " text/xml " );

conn.setRequestProperty( " Content-Length " , String.valueOf(postStr.length()));

conn.setDoOutput( true );

conn.setDoInput( true );

conn.connect();

PrintWriter out = new PrintWriter(conn.getOutputStream());

out.print(postStr);

out.flush();

out.close();

BufferedReader in = new BufferedReader( new InputStreamReader(conn.getInputStream()));

String inputLine;

while ((inputLine = in.readLine()) != null ) {

result += inputLine + " \n " ;

}

in.close();

System.out.println(htmlDecode(result));

} catch (Exception ex) {

System.out.println( " Error: " + ex.getMessage());

}
