如何在java中发起http和https请求

1.写http请求方法

[java] view plain copy

//处理http请求 requestUrl为请求地址 requestMethod请求方式，值为"GET"或"POST"

public static String httpRequest(String requestUrl,String requestMethod,String outputStr){

StringBuffer buffer=null;

try{

URL url=new URL(requestUrl);

HttpURLConnection conn=(HttpURLConnection)url.openConnection();

conn.setDoOutput(true);

conn.setDoInput(true);

conn.setRequestMethod(requestMethod);

conn.connect();

//往服务器端写内容也就是发起http请求需要带的参数

if(null!=outputStr){

OutputStream os=conn.getOutputStream();

os.write(outputStr.getBytes("utf-8"));

os.close();

}

//读取服务器端返回的内容

InputStream is=conn.getInputStream();

InputStreamReader isr=new InputStreamReader(is,"utf-8");

BufferedReader br=new BufferedReader(isr);

buffer=new StringBuffer();

String line=null;

while((line=br.readLine())!=null){

buffer.append(line);

}

}catch(Exception e){

e.printStackTrace();

}

return buffer.toString();

}

java http请求

可能是这个网站做了权限校验啥的吧，你在浏览器是先登录以后再请求的这个接口，但是你的JAVA客户端没有做登录，直接请求，被认为是非法请求，所以就不给你返回数据了

求解java怎样发送https请求

使用httpClient可以发送，具体的可以参考下面的代码

SSLClient类，继承至HttpClient

import java.security.cert.CertificateException;

import java.security.cert.X509Certificate;

import javax.net.ssl.SSLContext;

import javax.net.ssl.TrustManager;

import javax.net.ssl.X509TrustManager;

import org.apache.http.conn.ClientConnectionManager;

import org.apache.http.conn.scheme.Scheme;

import org.apache.http.conn.scheme.SchemeRegistry;

import org.apache.http.conn.ssl.SSLSocketFactory;

import org.apache.http.impl.client.DefaultHttpClient;

//用于进行Https请求的HttpClient

public class SSLClient extends DefaultHttpClient{

public SSLClient() throws Exception{

super();

SSLContext ctx = SSLContext.getInstance("TLS");

X509TrustManager tm = new X509TrustManager() {

@Override

public void checkClientTrusted(X509Certificate[] chain,

String authType) throws CertificateException {

}

@Override

public void checkServerTrusted(X509Certificate[] chain,

String authType) throws CertificateException {

}

@Override

public X509Certificate[] getAcceptedIssuers() {

return null;

}

};

ctx.init(null, new TrustManager[]{tm}, null);

SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

ClientConnectionManager ccm = this.getConnectionManager();

SchemeRegistry sr = ccm.getSchemeRegistry();

sr.register(new Scheme("https", 443, ssf));

}

HttpClient发送post请求的类

import java.util.ArrayList;

import java.util.Iterator;

import java.util.List;

import java.util.Map;

import java.util.Map.Entry;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.NameValuePair;

import org.apache.http.client.HttpClient;

import org.apache.http.client.entity.UrlEncodedFormEntity;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.message.BasicNameValuePair;

import org.apache.http.util.EntityUtils;

* 利用HttpClient进行post请求的工具类

public class HttpClientUtil {

public String doPost(String url,MapString,String map,String charset){

HttpClient httpClient = null;

HttpPost httpPost = null;

String result = null;

try{

httpClient = new SSLClient();

httpPost = new HttpPost(url);

//设置参数

ListNameValuePair list = new ArrayListNameValuePair();

Iterator iterator = map.entrySet().iterator();

while(iterator.hasNext()){

EntryString,String elem = (EntryString, String) iterator.next();

list.add(new BasicNameValuePair(elem.getKey(),elem.getValue()));

}

if(list.size() 0){

UrlEncodedFormEntity entity = new UrlEncodedFormEntity(list,charset);

httpPost.setEntity(entity);

}

HttpResponse response = httpClient.execute(httpPost);

if(response != null){

HttpEntity resEntity = response.getEntity();

if(resEntity != null){

result = EntityUtils.toString(resEntity,charset);

}

}catch(Exception ex){

ex.printStackTrace();

}

return result;

}

测试代码

import java.util.HashMap;

import java.util.Map;

//对接口进行测试

public class TestMain {

private String url = "";

private String charset = "utf-8";

private HttpClientUtil httpClientUtil = null;

public TestMain(){

httpClientUtil = new HttpClientUtil();

}

public void test(){

String httpOrgCreateTest = url + "httpOrg/create";

MapString,String createMap = new HashMapString,String();

createMap.put("authuser","*****");

createMap.put("authpass","*****");

createMap.put("orgkey","****");

createMap.put("orgname","****");

String httpOrgCreateTestRtn = httpClientUtil.doPost(httpOrgCreateTest,createMap,charset);

System.out.println("result:"+httpOrgCreateTestRtn);

}

public static void main(String[] args){

TestMain main = new TestMain();

main.test();

}
