最近做一接口,要通过JAVA类请求SERVLET ,DOPOST方法.
不知道怎么把我的参数传过去.在网上找了几个例子.
都不行.
方法一:
[code="java"]
package com.3sfg.setvlet;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.HashMap;
import java.util.Map;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpMethod;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.URIException;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.params.HttpMethodParams;
import org.apache.commons.httpclient.util.URIUtil;
import org.apache.commons.lang.StringUtils;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

public final class HttpTookit {
private static Log log = LogFactory.getLog(HttpTookit.class);/** * 执行一个HTTP GET请求，返回请求响应的HTML * * @param url 请求的URL地址 * @param queryString 请求的查询参数,可以为null * @param charset 字符集 * @param pretty 是否美化 * @return 返回请求响应的HTML */ public static String doGet(String url, String queryString, String charset, boolean pretty) { StringBuffer response = new StringBuffer(); HttpClient client = new HttpClient(); HttpMethod method = new GetMethod(url); try { if (StringUtils.isNotBlank(queryString)) //对get请求参数做了http请求默认编码，好像没有任何问题，汉字编码后，就成为%式样的字符串 method.setQueryString(URIUtil.encodeQuery(queryString)); client.executeMethod(method); if (method.getStatusCode() == HttpStatus.SC_OK) { BufferedReader reader = new BufferedReader(new InputStreamReader(method.getResponseBodyAsStream(), charset)); String line; while ((line = reader.readLine()) != null) { if (pretty) response.append(line).append(System.getProperty("line.separator")); else response.append(line); } reader.close(); } } catch (URIException e) { log.error("执行HTTP Get请求时，编码查询字符串“" + queryString + "”发生异常！", e); } catch (IOException e) { log.error("执行HTTP Get请求" + url + "时，发生异常！", e); } finally { method.releaseConnection(); } return response.toString(); } /** * 执行一个HTTP POST请求，返回请求响应的HTML * * @param url 请求的URL地址 * @param params 请求的查询参数,可以为null * @param charset 字符集 * @param pretty 是否美化 * @return 返回请求响应的HTML */ public static String doPost(String url, Map<String, String> params, String charset, boolean pretty) { StringBuffer response = new StringBuffer(); HttpClient client = new HttpClient(); HttpMethod method = new PostMethod(url); //设置Http Post数据 if (params != null) { HttpMethodParams p = new HttpMethodParams(); for (Map.Entry<String, String> entry : params.entrySet()) { p.setParameter(entry.getKey(), entry.getValue()); } p.setParameter("abc", "efg"); method.setParams(p); } try { client.executeMethod(method); if (method.getStatusCode() == HttpStatus.SC_OK) { BufferedReader reader = new BufferedReader(new InputStreamReader(method.getResponseBodyAsStream(), charset)); String line; while ((line = reader.readLine()) != null) { if (pretty) response.append(line).append(System.getProperty("line.separator")); else response.append(line); } reader.close(); } } catch (IOException e) { log.error("执行HTTP Post请求" + url + "时，发生异常！", e); } finally { method.releaseConnection(); } return response.toString(); } public static void main(String[] args) { Map<String, String> map = new HashMap<String, String>(); map.put("parax", "123456"); String y = doGet("http://127.0.0.1:8080/AIRP/servletTest", "xx=00", "GBK", true); String z = doPost("http://127.0.0.1:8080/AIRP/servletTest?", map, "GBK", false); System.out.println(y); System.out.println(z); }}[/code]
POST 方法 ,我在servletJ里,取不知任何参数,请求帮助.
感谢.
方法二:
[code="java"]
private static String testPost(String MSG_ID,String MOBILE_NO,String CONTENT,
String SERVICE_ID,String PASS,String SP_CODE,String LINK_ID,
String FEE_TYPE,String FEE_CODE) throws IOException {
URL url = new URL("http://127.0.0.1:8080/AIRP/servletTest");
URLConnection connection = url.openConnection();
connection.setDoOutput(true);
OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream(), "utf-8");
out.write("MSG_ID="+MSG_ID+"&MOBILE_NO="+MOBILE_NO+"&ACTION_ID=3"
+"&SERVICE_ID=99&PASS=asdfasd"
+"&SP_CODE=10625777&LINK_ID="); //向页面传递数据。post的关键所在！
// remember to clean up
out.flush();
out.close();
String sCurrentLine;
String sTotalString;
sCurrentLine = "";
sTotalString = "";
InputStream l_urlStream;
l_urlStream = connection.getInputStream();
// 传说中的三层包装阿！
BufferedReader l_reader = new BufferedReader(new InputStreamReader(
l_urlStream));
while ((sCurrentLine = l_reader.readLine()) != null) {
sTotalString += sCurrentLine + "\r\n";
}
System.out.println(sTotalString);
return sTotalString;
}
[/code]
if (params != null) {
HttpMethodParams p = new HttpMethodParams();
for (Map.Entry entry : params.entrySet()) {
p.setParameter(entry.getKey(), entry.getValue());
}
p.setParameter("abc", "efg");
method.setParams(p);
}
这样不知道怎么取不到参数...
