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代码调用post，以下Java通过post方式调用WebService代码java代码调用post：
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java代码调用post：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();
}
}

Q1: 如何用Java通过POST方法向HTTP接口传递数据？
这是corejava2的例子\x0d\x0aURLConnectionconnection=url.openConnection();//url为http服务器地址\x0d\x0aconnection.setDoOutput(true);\x0d\x0aPrintWriterout\x0d\x0a=newPrintWriter(connection.getOutputStream());//获得输出流\x0d\x0a//向服务器传递参数\x0d\x0aEnumerationenum=nameValuePairs.keys();\x0d\x0awhile(enum.hasMoreElements())\x0d\x0a{Stringname=(String)enum.nextElement();\x0d\x0aStringvalue=nameValuePairs.getProperty(name);\x0d\x0acharch;\x0d\x0aif(enum.hasMoreElements())ch='';elsech='\n';\x0d\x0aout.print(name+"="\x0d\x0a+URLEncoder.encode(value)+ch);\x0d\x0aSystem.out.println(name+value);\x0d\x0a}\x0d\x0a\x0d\x0aout.close();\x0d\x0a//获取输入流\x0d\x0aBufferedReaderin;\x0d\x0atry\x0d\x0a{in=newBufferedReader(new\x0d\x0aInputStreamReader(connection.getInputStream()));\x0d\x0a}\x0d\x0acatch(FileNotFoundExceptionexception)\x0d\x0a{InputStreamerr\x0d\x0a=((HttpURLConnection)connection).getErrorStream();\x0d\x0aif(err==null)throwexception;\x0d\x0ain=newBufferedReader(newInputStreamReader(err));\x0d\x0a}\x0d\x0aStringBufferresponse=newStringBuffer();\x0d\x0aStringline;\x0d\x0a//读取数据\x0d\x0awhile((line=in.readLine())!=null)\x0d\x0aresponse.append(line+"\n");\x0d\x0a\x0d\x0ain.close();\x0d\x0areturnresponse.toString();\x0d\x0a}\x0d\x0a}
Q2: 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);

out.close();
}

in.close();
}
}
catch(IOException ex){

Q3: java中怎样用post，get，put请求
java中用post，get，put请求方法：
public static String javaHttpGet(String url,String charSet){
String resultData = null;
try {
URL pathUrl = new URL(url); //创建一个URL对象
HttpURLConnection urlConnect = (HttpURLConnection) pathUrl.openConnection(); //打开一个HttpURLConnection连接
urlConnect.setConnectTimeout(30000); // 设置连接超时时间
urlConnect.connect();
if (urlConnect.getResponseCode() == 200) { //请求成功
resultData = readInputStream(urlConnect.getInputStream(), charSet);
}
} catch (MalformedURLException e) {
LogL.getInstance().getLog().error("URL出错！", e);
} catch (IOException e) {
LogL.getInstance().getLog().error("读取数据流出错！", e);
}
return resultData;
}
public static String javaHttpPost(String url,MapString,Object map,String charSet){
String resultData=null;
StringBuffer params = new StringBuffer();
try {
IteratorEntryString, Object ir = map.entrySet().iterator();
while (ir.hasNext()) {
Map.EntryString, Object entry = (Map.EntryString, Object) ir.next();
params.append(URLEncoder.encode(entry.getKey(),charSet) + "=" + URLEncoder.encode(entry.getValue().toString(), charSet) + "");
}
byte[] postData = params.deleteCharAt(params.length()).toString().getBytes();
URL pathUrl = new URL(url); //创建一个URL对象
HttpURLConnection urlConnect = (HttpURLConnection) pathUrl.openConnection();
urlConnect.setConnectTimeout(30000); // 设置连接超时时间
urlConnect.setDoOutput(true); //post请求必须设置允许输出
urlConnect.setUseCaches(false); //post请求不能使用缓存
urlConnect.setRequestMethod("POST"); //设置post方式请求
urlConnect.setInstanceFollowRedirects(true);
urlConnect.setRequestProperty("Content-Type","application/x-www-form-urlencoded; charset="+charSet);// 配置请求Content-Type
urlConnect.connect(); // 开始连接
DataOutputStream dos = new DataOutputStream(urlConnect.getOutputStream()); // 发送请求参数
dos.write(postData);
dos.flush();
dos.close();
if (urlConnect.getResponseCode() == 200) { //请求成功
resultData = readInputStream(urlConnect.getInputStream(),charSet);
}
} catch (MalformedURLException e) {
LogL.getInstance().getLog().error("URL出错！", e);
} catch (IOException e) {
LogL.getInstance().getLog().error("读取数据流出错！", e);
} catch (Exception e) {
LogL.getInstance().getLog().error("POST出错！", e);
}
return resultData;
}
