最简单易懂的webService客户端之soap+xml请求

代码准备:

  1.网络上有提供一些免费的服务器测试地址,可以上这里找一找:https://my.oschina.net/CraneHe/blog/183471

  2.我选择了一个翻译地址:http://www.webxml.com.cn/WebServices/TranslatorWebService.asmx

    2.1打开之后看到该地址下有一个方法:

    2.2点击进入,网站会提供该方法的客户端请求xml格式:

最简单易懂的webService客户端之soap+xml请求

    2.3,这个红框部分就是我们要的,将它写入代码,就可以完成请求了.

    注意:以上还是获取soap请求xml的方法,也是比较入门的方式,有经验的筒子直接上wsdl利用解释文档也可以自己写xml...

然后是代码,我直接附上代码,大家直接复制即可运行,附注释.

Translate.class
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
/**

*/ public class Translate {
public static void translate(String word ) throws Exception {
//地址
String urlString = "http://www.webxml.com.cn/WebServices/TranslatorWebService.asmx ";
//方法
String soapActionString = "http://WebXml.com.cn/getEnCnTwoWayTranslator";
URL url = new URL(urlString);
HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
//拼接请求体,此处也可以在外面写xml文件然后读取,但是为了方便一个文件搞定,而且参数也比较好传递我们直接String拼接(直接将网页上的复制进来即可)
String soap = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" +
"<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/\">\n" +
" <soap:Body>\n" +
" <getEnCnTwoWayTranslator xmlns=\"http://WebXml.com.cn/\">\n" +
" <Word>" + word + "</Word>\n" +
" </getEnCnTwoWayTranslator>\n" +
" </soap:Body>\n" +
"</soap:Envelope>";
byte[] buf = soap.getBytes();
//设置一些头参数
httpConn.setRequestProperty("Content-Length", String.valueOf(buf.length));
httpConn.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
httpConn.setRequestProperty("soapActionString", soapActionString);
httpConn.setRequestMethod("POST");
//输入参数和输出结果
httpConn.setDoOutput(true);
httpConn.setDoInput(true);
OutputStream out = httpConn.getOutputStream();
out.write(buf);
out.close(); //最后合格解析结果大家就各显神通了,此处打印出解析的过程,最终得到翻译答案
byte[] datas = readInputStream(httpConn.getInputStream());
String result = new String(datas);
System.out.println("result:" + result);
System.out.println(result.substring(result.indexOf("string") - 1,result.lastIndexOf("string") + 7));
System.out.println(result.substring(result.indexOf("string") - 1,result.lastIndexOf("string") + 7).replaceAll("</{0,1}(string)?>",""));
} /**
* 从输入流中读取数据
*
* @param inStream
* @return
* @throws Exception
*/
public static byte[] readInputStream(InputStream inStream) throws Exception {
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int len = 0;
while ((len = inStream.read(buffer)) != -1) {
outStream.write(buffer, 0, len);
}
byte[] data = outStream.toByteArray();
outStream.close();
inStream.close();
return data;
} public static void main(String[] args) throws Exception {
translate("sea");
}
}

运行结果:

result:<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><getEnCnTwoWayTranslatorResponse xmlns="http://WebXml.com.cn/"><getEnCnTwoWayTranslatorResult><string>sea: [ si: ]</string><string>n. 海,海洋 |</string></getEnCnTwoWayTranslatorResult></getEnCnTwoWayTranslatorResponse></soap:Body></soap:Envelope>
<string>sea: [ si: ]</string><string>n. 海,海洋 |</string>
sea: [ si: ]n. 海,海洋 |

  第一行是直接返回的结果,下面两行帮助理解解析,最后得到sea单词的解释,是不是简单清楚...

  第二期补充:有筒子可能有问题,那我要写的soap只有wsdl地址怎么办,而且还要求有请求头验证,这个我也找了之前写的一个请求代码,同样非常简单,用到的jar包只有httpclient

//拼接xml请求,带有请求头
String params = "<id>5</id>";//随手举个例子,类似...
String soapRequestData = "<soapenv:Envelope \n" +

String method = "请求地址";//比如http://192.177.222.222:8888/services/Service_Name/Function_Name
PostMethod postMethod = new PostMethod(method);
byte[] b = soapRequestData.getBytes("utf-8");
InputStream is = new ByteArrayInputStream(b, 0, b.length);
RequestEntity re = new InputStreamRequestEntity(is, b.length, "application/soap+xml; charset=utf-8");
postMethod.setRequestEntity(re); HttpClient httpClient = new HttpClient();
int statusCode = httpClient.executeMethod(postMethod);
//200说明正常返回数据
if (statusCode != 200) {
//internet error
System.out.println(statusCode);
}
soapRequestData = postMethod.getResponseBodyAsString();
System.out.println(soapRequestData);
} catch (Exception e) {
e.printStackTrace();
}
}
}

好了,将这个简单的代码复制进去,替换一下请求头和请求地址以及参数就可以得到反馈就过了,试用一下吧.
