java的post代码 java postmethod

IT技术PostMethod

java语言使用post方式调用webService方式WebService可以有Get、 Post、Soap、Document四种方式调用java的post代码，以下Java通过post方式调用WebService代码java的post代码：
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLEncoder;
import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
/**
* 功能描述：WebService调用
*
*/
public class ClientTest {
/**
* 功能描述：HTTP-POST
*
*/
public String post() {
OutputStreamWriter out = null;
StringBuilder sTotalString = new StringBuilder();
try {
URL urlTemp = new URL(
"");
URLConnection connection = urlTemp.openConnection();
connection.setDoOutput(true);
out = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
StringBuffer sb = new StringBuffer();
sb.append("byProvinceName=福建");
out.write(sb.toString());
out.flush();
String sCurrentLine;
sCurrentLine = "";
InputStream l_urlStream;
l_urlStream = connection.getInputStream();// 请求
BufferedReader l_reader = new BufferedReader(new InputStreamReader(
l_urlStream));
while ((sCurrentLine = l_reader.readLine()) != null) {
sTotalString.append(sCurrentLine);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (null != out) {
try {
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return sTotalString.toString();
}
}
java 怎样发送 POSTprivate void postMethod(String url) throws IOException
{
url = "";
PostMethod postMethod = new PostMethod(url);
// 填入各个表单域的值
NameValuePair[] data = https://www.04ip.com/post/{ new NameValuePair("id", "herrapfel"),new NameValuePair("passwd", "") };
// 将表单的值放入postMethod中
postMethod.setRequestBody(data);
// 执行postMethod
int statusCode = httpClient.executeMethod(postMethod);
System.out.println(" status code:"statusCode);
// HttpClient对于要求接受后继服务的请求，象POST和PUT等不能自动处理转发
if(statusCode == HttpStatus.SC_OK)
{
StringBuffer contentBuffer = new StringBuffer();
InputStream in = postMethod.getResponseBodyAsStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(in,postMethod.getResponseCharSet()));
String inputLine = null;
while((inputLine = reader.readLine()) != null)
{
contentBuffer.append(inputLine);
System.out.println("input line:"inputLine);
contentBuffer.append("/n");
}
in.close();
}
else if (statusCode == HttpStatus.SC_MOVED_PERMANENTLY || statusCode == HttpStatus.SC_MOVED_TEMPORARILY)
{
// 从头中取出转向的地址
Header locationHeader = postMethod.getResponseHeader("location");
String location = null;
if (locationHeader != null)
{
location = locationHeader.getValue();
System.out.println("The page was redirected to:"location);
}
else
{
System.err.println("Location field value is null.");
}
}

}
如何使用java发送post请求/**
* 向指定 URL 发送POST方法的请求
*
* @param url
*发送请求的 URL
* @param param
*请求参数，请求参数应该是 name1=value1name2=value2 的形式 。
* @return 所代表远程资源的响应结果
*/
public static String sendPost(String url, String param) {
PrintWriter out = null;
BufferedReader in = null;
String result = "";
try {
URL realUrl = new URL(url);
// 打开和URL之间的连接
URLConnection conn = realUrl.openConnection();
// 设置通用的请求属性
conn.setRequestProperty("accept", "*/*");
conn.setRequestProperty("connection", "Keep-Alive");
conn.setRequestProperty("user-agent",
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
// 发送POST请求必须设置如下两行
conn.setDoOutput(true);
conn.setDoInput(true);
// 获取URLConnection对象对应的输出流
out = new PrintWriter(conn.getOutputStream());
// 发送请求参数
out.print(param);
// flush输出流的缓冲
out.flush();
// 定义BufferedReader输入流来读取URL的响应
in = new BufferedReader(
new InputStreamReader(conn.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
result= line;
}
} catch (Exception e) {
System.out.println("发送 POST 请求出现异常！" e);
e.printStackTrace();
}
//使用finally块来关闭输出流、输入流
finally{
try{
if(out!=null){
out.close();
}
if(in!=null){
in.close();
}
}
catch(IOException ex){
ex.printStackTrace();
}
}
return result;
}
