Post提交

1.java 和 android 的提交方式都是一样的。

客户端的提交如下

HttpRequest.java---------------->

package com.unam.phonegap.plugin;

import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;

public class HttpRequest {

public static boolean sendXML(String path, String xml)throws Exception{
byte[] data = xml.getBytes();
URL url = new URL(path);
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
conn.setRequestMethod("POST");
conn.setConnectTimeout(5 * 1000);
conn.setDoOutput(true);//如果通过post提交数据，必须设置允许对外输出数据
conn.setRequestProperty("Content-Type", "text/xml; charset=UTF-8");
conn.setRequestProperty("Content-Length", String.valueOf(data.length));
OutputStream outStream = conn.getOutputStream();
outStream.write(data);
outStream.flush();
outStream.close();
if(conn.getResponseCode()==200){
return true;
}
return false;
}

public static boolean sendGetRequest(String path, Map<String, String> params, String enc) throws Exception{
StringBuilder sb = new StringBuilder(path);
sb.append('?');
// ?method=save&title=435435435&timelength=89&
for(Map.Entry<String, String> entry : params.entrySet()){
sb.append(entry.getKey()).append('=')
.append(URLEncoder.encode(entry.getValue(), enc)).append('&');
}
sb.deleteCharAt(sb.length()-1);

URL url = new URL(sb.toString());
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
conn.setRequestMethod("GET");
conn.setConnectTimeout(5 * 1000);
if(conn.getResponseCode()==200){
return true;
}
return false;
}

public static boolean sendPostRequest(String path, Map<String, String> params, String enc) throws Exception{
System.out.println("sendPostRequest");
StringBuilder sb = new StringBuilder();
if(params!=null && !params.isEmpty()){
for(Map.Entry<String, String> entry : params.entrySet()){
sb.append(entry.getKey()).append('=')
.append(URLEncoder.encode(entry.getValue(), enc)).append('&');
}
sb.deleteCharAt(sb.length()-1);
}
byte[] entitydata = sb.toString().getBytes();//得到实体的二进制数据
URL url = new URL(path);
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
conn.setRequestMethod("POST");
conn.setConnectTimeout(5 * 1000);
conn.setDoOutput(true);//如果通过post提交数据，必须设置允许对外输出数据
//Content-Type: application/x-www-form-urlencoded
//Content-Length: 38
//TODO: 怎么获取type
conn.setRequestProperty("Content-Type", "application/json;charset=utf-8");
conn.setRequestProperty("Content-Length", String.valueOf(entitydata.length));
OutputStream outStream = conn.getOutputStream();
outStream.write(entitydata);
outStream.flush();
outStream.close();
if(conn.getResponseCode()==200){
System.out.println("success");
return true;
}
System.out.println(conn.getResponseCode());
System.out.println("false");
return false;
}

//SSL HTTPS Cookie
public static boolean sendRequestFromHttpClient(String path, Map<String, String> params, String enc) throws Exception{
List<NameValuePair> paramPairs = new ArrayList<NameValuePair>();
if(params!=null && !params.isEmpty()){
for(Map.Entry<String, String> entry : params.entrySet()){
paramPairs.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
}
}
UrlEncodedFormEntity entitydata = new UrlEncodedFormEntity(paramPairs, enc);//得到经过编码过后的实体数据
HttpPost post = new HttpPost(path); //form
post.setEntity(entitydata);
DefaultHttpClient client = new DefaultHttpClient(); //浏览器
HttpResponse response = client.execute(post);//执行请求
if(response.getStatusLine().getStatusCode()==200){
return true;
}
return false;
}
}

 

客户端提交：

Map<String,String> params= new HashMap<String,String>();
params.put("url", url); //设置参数
HttpRequest.sendPostRequest("这里放提交的地址", params, "utf-8"); //post提交到平台
System.out.println("222");

 

 

服务端的接收：

// String name=request.getParameter("params");
// System.out.println(name); //null

byte[] data=request.getParameter("params").getBytes("ISO-8859-1");
String ysj=new String(data,"utf-8");
System.out.println("params:"+params);
