Java处理Http请求的几种方式总结:
1.commons-httpclient 简洁快速模拟HTTP请求
<dependency>
<groupId>commons-httpclient</groupId>
<artifactId>commons-httpclient</artifactId>
<version>3.1</version>
</dependency>
(1) 代码如下
import java.io.IOException;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.methods.PostMethod;
/**
* Hello world!
*
*/
public class App {
private static final HttpClient client = new HttpClient();
public static void main(String[] args) throws HttpException, IOException, InterruptedException {
for (int i = 0; i < 2000; i++) {
PostMethod method = new PostMethod("http://open.kaduoyun.com/api/v1.0/sendMsg.htm");
//http://localhost:8080/vs-rest/rs/user/register/gaozz/jerrison/gaozhenzhai@126.com/123456/test/0/30/addrtest/18600635193/touxiang/1100
method.getParams().setContentCharset("UTF-8");
method.addParameter("appkey", "38F325796F584656946801146D177C18");
method.addParameter("appsecret", "4451E66CDBAE8C01FC1B12D70CDFA077");
method.addParameter("title", "测试标题");
method.addParameter("content", "测试内容"+i);
//method.addParameter("clientid", "");
client.executeMethod(method);
System.out.println(method.getResponseBodyAsString()+i);
Thread.sleep(10);
}
}
}
(2)
import java.io.IOException;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.methods.PostMethod;
/**
* Hello world!
*
*/
public class UserTestApp {
private static final HttpClient client = new HttpClient();
private static final String urlStr = "http://192.168.0.117:8080";
//private static final String urlStr = "http://192.168.0.110:8080/vs-rest";
public static void main(String[] args) throws HttpException, IOException, InterruptedException {
//testLogin();
//testSearchCity();
//testRegister();
testFindPassword();
//testVerifyUnique();
//testUpdateUserInfo();
//testSearch();
//testSchoolCompetitor();
//testSignUp();
//testVote();
}
public static void testRegister() throws HttpException, IOException, InterruptedException{
PostMethod method = new PostMethod(urlStr+"/rs/user/register");
//http://localhost:8080/vs-rest/rs/user/register/gaozz/jerrison/gaozhenzhai@126.com/123456/test/0/30/addrtest/18600635193/touxiang/1100
method.getParams().setContentCharset("UTF-8");
method.addParameter("userName", "gaozz");
method.addParameter("nickName", "jerrison11");
method.addParameter("email", "gaozhenzhai11@126.com");
method.addParameter("password", "123456");
method.addParameter("equipmentId", "test818");
method.addParameter("sex", "0");
method.addParameter("age", "30");
method.addParameter("addr", "addrtest");
method.addParameter("phone", "18600635193");
method.addParameter("avatar", "touxiang");
method.addParameter("birthday", "1100");
client.executeMethod(method);
System.out.println(method.getResponseBodyAsString());
Thread.sleep(10);
}
public static void testLogin() throws HttpException, IOException, InterruptedException{
PostMethod method = new PostMethod(urlStr+"/rs/user/login");
method.getParams().setContentCharset("UTF-8");
method.addParameter("userName", "gaozz");
method.addParameter("password", "654321");
client.executeMethod(method);
System.out.println(method.getResponseBodyAsString());
Thread.sleep(10);
}
public static void testFindPassword() throws HttpException, IOException, InterruptedException{
PostMethod method = new PostMethod(urlStr+"/rs/user/findPassword");
method.getParams().setContentCharset("UTF-8");
method.addParameter("userName", "slaton");
method.addParameter("verifyCode", "060468");
method.addParameter("newPassword", "12345678");
client.executeMethod(method);
System.out.println(method.getResponseBodyAsString());
Thread.sleep(10);
}
}
2.apache org.apache.httpcomponents httpclient
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.2</version>
</dependency>
参考new version 4.5 新版本代码如下：
importorg.apache.http.HttpEntity;
import org.apache.http.NameValuePair;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.params.CoreConnectionPNames;
import org.apache.http.util.EntityUtils;
public static String httpPostUrlForPdf(String url) {
// 设置HTTP请求参数
String result = null;
CloseableHttpClient client = HttpClients.createDefault();
HttpGet httpGet = new HttpGet(url);
try {
CloseableHttpResponse response = client.execute(httpGet);
result = EntityUtils.toString(response.getEntity(), "UTF-8");
} catch (ClientProtocolException e) {
logger.error("http接口调用异常：url is::" + url, e);
return null;
} catch (IOException e) {
logger.error("http接口调用异常：url is::" + url, e);
return null;
} finally {
try {
client.close();
} catch (IOException e) {
logger.error("http接口调用异常：url is::" + url, e);
}
}
return result;
}
old version 4.3版本代码如下 :
public static String httpPost(String url, String jsonString) {
// 设置HTTP请求参数
String result = null;
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
try {
httpClient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 10000);//设置请求超时时间 10s
StringEntity entity = new StringEntity(jsonString);
entity.setContentEncoding("UTF-8");
entity.setContentType("application/json");
httpPost.setEntity(entity);
HttpEntity resEntity = httpClient.execute(httpPost).getEntity();
result = EntityUtils.toString(resEntity, "UTF-8");
} catch (Exception e) {
logger.error("http接口调用异常：url is::" + url, e);
return null;
} finally {
httpClient.getConnectionManager().shutdown();
}
return result;
}
调用代码如下：
ReqChedaiParamDataVo dataVo = new ReqChedaiParamDataVo();
dataVo.setIdCard(idCard);
Map<String, Object> map = new HashMap<String, Object>();
map.put("content", dataVo);
String jsonString = JSONObject.toJSONString(map);
LOGGER.info("请求对象json::" + jsonString);
String response = HttpUtils.httpPost(queryMemberInfoHttpUrl, jsonString);
LOGGER.info("响应字符串::" + response);
Another:
HttpPost httpPost22 = new HttpPost("http://test.com/abc");
List<NameValuePair> nvps = new ArrayList<NameValuePair>();
nvps.add(new BasicNameValuePair("username", "vip"));
nvps.add(new BasicNameValuePair("password", "secret"));
try {
httpPost22.setEntity(new UrlEncodedFormEntity(nvps));
httpClient.execute(httpPost);
} catch (IOException e) {
e.printStackTrace();
}
