httpclient的使用

一.httpclient客户端:

@Test
public void testSendMsg() throws Exception {

HttpClient client = new HttpClient();

//设置主机名和端口名
client.getHostConfiguration().setHost("http://localhost:8080/", 8080);

//设置post的方法
PostMethod post = new PostMethod("http://localhost:8080/rili_service/inner/SendMsg.action");
//防止中文参数的乱码

post.addRequestHeader("Content-Type","application/x-www-form-urlencoded;charset=utf-8");
//设置post过去的参数
post.addParameter(new NameValuePair("sourceTermMDN","1182026"));
post.addParameter(new NameValuePair("destTermMDN", "18910895580;18951732225"));
post.addParameter(new NameValuePair("messageContent",new String("收到的中文,有乱码吗?".getBytes("utf-8"))));
post.addParameter(new NameValuePair("userId", "99016768226"));
post.addParameter(new NameValuePair("sendIp", ""));
post.addParameter(new NameValuePair("sendType", "1"));

client.executeMethod(post);
//取返回码
String responseString = post.getResponseBodyAsString();
System.out.println("responseString="+responseString);

//取返回页面的状态码,为200表示正常返回;
System.out.println("状态码="+post.getStatusCode());
System.out.println("开始post.........");
Cookie[] cookies = client.getState().getCookies();

client.getState().addCookies(cookies);
post.releaseConnection();

}

二.接收httpclient 传过来的参数

public String SendMsg()
{
System.out.println("开始SendMsg......");
int result=0;

//接收post过来的参数
String sourceTermMDN=getStringValue("sourceTermMDN");
String[] destTermMDN=getStringValue("destTermMDN").split(";");
String messageContent=getStringValue("messageContent");
String userId=getStringValue("userId");
String sendIp=getStringValue("sendIp");
String sendType=getStringValue("sendType");

//调用的业务处理函数
result=smsService.sendSysSms(id, sourceTermMDN, destTermMDN, messageContent, userId, sendIp, sendType);

System.out.println("结束SendMsg......");
//输出回应页面
doOutput(String.valueOf(result));
return null;
}

/**
* 获得传递的参数值
* @param key　参数名称
* @return 参数值
*/
public String getStringValue(String key) {
try {
return ((String[]) ActionContext.getContext().getParameters().get(key))[0];
}
catch(Exception ex) {
return "";
}
}

public void doOutput(String content) {
HttpServletResponse response = getResponse();
response.setCharacterEncoding("UTF-8");
try {
OutputStream os = response.getOutputStream();
os.write(content.getBytes("UTF-8"));
os.flush();
os.close();
if(logger.isDebugEnabled()){
logger.debug("response content:" + content);
}
} catch (IOException e) {
logger.error(e);
}
}
