https和http协议接口post请求接口方法-蒲公英云

一、只针对http 的post请求

package test;

import java.io.InputStreamReader;

import java.net.URI;

import net.sf.json.JSONObject;

import org.apache.http.Header;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.client.HttpClient;

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

import org.apache.http.entity.StringEntity;

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

import org.apache.http.util.EntityUtils;

public class HttpClientRequest {

public static String post(String url,JSONObject json, String token){

String result = null;

    HttpClient client = new DefaultHttpClient();  
    HttpPost request;  
    try \{  
        request = new HttpPost(new URI(url)); 
        if(json != null)\{ 
        StringEntity s = new StringEntity(json.toString(),"utf-8");

s.setContentType(“application/json”);

request.setEntity(s);

        \}
        if(token != null)\{ 
        request.setHeader("token", token);
        \}
        HttpResponse response = client.execute(request); 
        int returncode = response.getStatusLine().getStatusCode();
        System.out.println("Response Code:"+returncode);
        if (returncode == 200) \{ 
        Header\[\] header = response.getHeaders("token");
        if(header.length >0)\{ 
        for(Header h:header)\{ 
        System.out.println(h.getName()+" "+h.getValue());
        \}
        \}
        HttpEntity entity = response.getEntity();
        long contentLen = entity.getContentLength();
        if(contentLen == 0)\{ 
        return "User Has No Authority";
        \}

String charset = EntityUtils.getContentCharSet(entity);

InputStreamReader isr = new InputStreamReader(entity.getContent(), charset);

StringBuffer sb = new StringBuffer();

char[] ct = new char[64];

int len = 0;

while((len = isr.read(ct))!=-1){

String sst = new String(ct);

sst = sst.substring(0, len).trim();

sb.append(sst);

}

result = sb.toString().replace(“\\\“”, “\“”);

result = result.substring(1, result.length()-1);

        \}
    \} catch(Exception e) \{ 
    e.printStackTrace();
    \}
    return result;

}

二、针对https和http都可以的post请求

package https;

import javax.net.ssl.HttpsURLConnection;

import javax.net.ssl.SSLContext;

import javax.net.ssl.SSLSession;

import javax.net.ssl.TrustManager;

import javax.net.ssl.X509TrustManager;

import net.sf.json.JSONObject;

import org.apache.commons.httpclient.ProtocolException;

import org.apache.http.Header;

import org.apache.http.HttpEntity;

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

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

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

import org.apache.http.entity.HttpEntityWrapper;

import org.apache.http.entity.StringEntity;

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

import org.apache.http.util.EntityUtils;

public class HttpsUtil{

static class TrustAnyTrustManager implements X509TrustManager{

@Override

public void checkClientTrusted(X509Certificate[] arg0, String arg1)

throws CertificateException {

}

throws CertificateException {

}

@Override

public X509Certificate[] getAcceptedIssuers() {

// TODO Auto-generated method stub

return null;

}

static class TrustAnyHostnameVerifier implements HostnameVerifier{

@Override

public boolean verify(String arg0, SSLSession arg1) {

// TODO Auto-generated method stub

return true;

}
