httpost.setEntity(new UrlEncodedFormEntity(name_value_pair, StandardCharsets.UTF_8));

HttpResponse response = httpclient.execute(httpost);

HttpEntity entity = response.getEntity();

body = EntityUtils.toString(entity);

} finally {

httpclient.getConnectionManager().shutdown();

}

return body;

}

public static String do_get(String url) throws ClientProtocolException, IOException {

String body = "{}";

DefaultHttpClient httpclient = new DefaultHttpClient();

try {

HttpGet httpget = new HttpGet(url);

HttpResponse response = httpclient.execute(httpget);

HttpEntity entity = response.getEntity();

body = EntityUtils.toString(entity);

} finally {

httpclient.getConnectionManager().shutdown();

}

return body;

}

如何使用java开发微信公众平台接口

1、首先，要在微信公众平台给你的账号申请到“高级功能” ；前台也就是菜单要想个性化设置必须要有这个功能，不然你只能添加菜单和关闭，但不能删除，还有自动回复也是。

2、后台要看你自己了。

微信开发平台中有个接口是上传多媒体文件，我用的是java 开发的，我怎么样才能在后台实现呢？代码如下：

/**

* 文件上传到微信服务器

* @param fileType 文件类型

* @param filePath 文件路径

* @return JSONObject

* @throws Exception

public static JSONObject send(String fileType, String filePath) throws Exception {

String result = null;

File file = new File(filePath);

if (!file.exists() || !file.isFile()) {

throw new IOException("文件不存在");

}

/**

* 第一部分

URL urlObj = new URL(""+ getAccess_token() + "type="+fileType+"");

HttpURLConnection con = (HttpURLConnection) urlObj.openConnection();

con.setRequestMethod("POST"); // 以Post方式提交表单，默认get方式

con.setDoInput(true);

con.setDoOutput(true);

con.setUseCaches(false); // post方式不能使用缓存

// 设置请求头信息

con.setRequestProperty("Connection", "Keep-Alive");

con.setRequestProperty("Charset", "UTF-8");

// 设置边界

String BOUNDARY = "----------" + System.currentTimeMillis();

con.setRequestProperty("Content-Type", "multipart/form-data; boundary="+ BOUNDARY);

// 请求正文信息

// 第一部分：

StringBuilder sb = new StringBuilder();

sb.append("--"); // 必须多两道线

sb.append(BOUNDARY);

sb.append("\r\n");

sb.append("Content-Disposition: form-data;name=\"file\";filename=\""+ file.getName() + "\"\r\n");

sb.append("Content-Type:application/octet-stream\r\n\r\n");

byte[] head = sb.toString().getBytes("utf-8");

// 获得输出流

OutputStream out = new DataOutputStream(con.getOutputStream());

// 输出表头

out.write(head);

// 文件正文部分

// 把文件已流文件的方式推入到url中

DataInputStream in = new DataInputStream(new FileInputStream(file));

int bytes = 0;

byte[] bufferOut = new byte[1024];

while ((bytes = in.read(bufferOut)) != -1) {

out.write(bufferOut, 0, bytes);

}

in.close();

// 结尾部分

byte[] foot = ("\r\n--" + BOUNDARY + "--\r\n").getBytes("utf-8");// 定义最后数据分隔线

out.write(foot);

out.flush();

out.close();

StringBuffer buffer = new StringBuffer();

BufferedReader reader = null;

try {

// 定义BufferedReader输入流来读取URL的响应

reader = new BufferedReader(new InputStreamReader(con.getInputStream()));

String line = null;

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

//System.out.println(line);

buffer.append(line);

}

if(result==null){

result = buffer.toString();

}

} catch (IOException e) {

System.out.println("发送POST请求出现异常！" + e);

e.printStackTrace();

throw new IOException("数据读取异常");

} finally {

if(reader!=null){

reader.close();

}

JSONObject jsonObj =new JSONObject(result);

return jsonObj;

}

怎么用java调用微信支付接口

java调用微信支付接口方法：

RequestHandler requestHandler = new RequestHandler(super.getRequest(),super.getResponse());

//获取token //两小时内有效，两小时后重新获取

Token = requestHandler.GetToken();

//更新token 到应用中

requestHandler.getTokenReal();

System.out.println("微信支付获取token=======================:" +Token);

//requestHandler 初始化

requestHandler.init();

requestHandler.init(appid,appsecret, appkey,partnerkey, key);

// --------------------------------本地系统生成订单-------------------------------------

// 设置package订单参数

SortedMapString, String packageParams = new TreeMapString, String();

packageParams.put("bank_type", "WX"); // 支付类型

packageParams.put("body", "xxxx"); // 商品描述

packageParams.put("fee_type", "1"); // 银行币种

packageParams.put("input_charset", "UTF-8"); // 字符集

packageParams.put("notify_url", ""); // 通知地址这里的通知地址使用外网地址测试，注意80端口是否打开。

packageParams.put("out_trade_no", no); // 商户订单号

packageParams.put("partner", partenerid); // 设置商户号

packageParams.put("spbill_create_ip", super.getRequest().getRemoteHost()); // 订单生成的机器IP，指用户浏览器端IP

packageParams.put("total_fee", String.valueOf(rstotal)); // 商品总金额,以分为单位

// 设置支付参数

SortedMapString, String signParams = new TreeMapString, String();

signParams.put("appid", appid);

signParams.put("noncestr", noncestr);

signParams.put("traceid", PropertiesUtils.getOrderNO());

signParams.put("timestamp", timestamp);

signParams.put("package", packageValue);

signParams.put("appkey", this.appkey);

// 生成支付签名，要采用URLENCODER的原始值进行SHA1算法！

String sign ="";

try {

sign = Sha1Util.createSHA1Sign(signParams);

} catch (Exception e) {

e.printStackTrace();

}

// 增加非参与签名的额外参数

signParams.put("sign_method", "sha1");

signParams.put("app_signature", sign);

// api支付拼包结束------------------------------------

//获取prepayid

String prepayid = requestHandler.sendPrepay(signParams);

System.out.println("prepayid :" + prepayid);

// --------------------------------生成完成---------------------------------------------

//生成预付快订单完成，返回给android,ios 掉起微信所需要的参数。

SortedMapString, String payParams = new TreeMapString, String();

payParams.put("appid", appid);

payParams.put("noncestr", noncestr);

payParams.put("package", "Sign=WXPay");

payParams.put("partnerid", partenerid);

payParams.put("prepayid", prepayid);

payParams.put("appkey", this.appkey);

//这里除1000 是因为参数长度限制。

int time = (int) (System.currentTimeMillis() / 1000);

payParams.put("timestamp",String.valueOf(time));

System.out.println("timestamp:" + time);

//签名

String paysign ="";

try {

paysign = Sha1Util.createSHA1Sign(payParams);

} catch (Exception e) {

e.printStackTrace();

}

payParams.put("sign", paysign);

//拼json 数据返回给客户端

BasicDBObject backObject = new BasicDBObject();

backObject.put("appid", appid);

backObject.put("noncestr", payParams.get("noncestr"));

backObject.put("package", "Sign=WXPay");

backObject.put("partnerid", payParams.get("partnerid"));

backObject.put("prepayid", payParams.get("prepayid"));

backObject.put("appkey", this.appkey);

backObject.put("timestamp",payParams.get("timestamp"));

backObject.put("sign",payParams.get("sign"));

String backstr = dataObject.toString();

System.out.println("backstr:" + backstr);

return backstr;

====================到此为止，预付款订单已生成，并且已返回客户端====================

//坐等微信服务器通知，通知的地址就是生成预付款订单的notify_url

ResponseHandler resHandler = new ResponseHandler(request, response);

resHandler.setKey(partnerkey);

//创建请求对象

//RequestHandler queryReq = new RequestHandler(request, response);

//queryReq.init();

if (resHandler.isTenpaySign() == true) {

//商户订单号

String out_trade_no = resHandler.getParameter("out_trade_no");

System.out.println("out_trade_no:" + out_trade_no);

//财付通订单号

String transaction_id = resHandler.getParameter("transaction_id");

System.out.println("transaction_id:" + transaction_id);

//金额,以分为单位

String total_fee = resHandler.getParameter("total_fee");

//如果有使用折扣券，discount有值，total_fee+discount=原请求的total_fee

String discount = resHandler.getParameter("discount");

//支付结果

String trade_state = resHandler.getParameter("trade_state");

//判断签名及结果

if ("0".equals(trade_state)) {

//------------------------------

//即时到账处理业务开始

//------------------------------

System.out.println("----------------业务逻辑执行-----------------");

//——请根据您的业务逻辑来编写程序（以上代码仅作参考）——

System.out.println("----------------业务逻辑执行完毕-----------------");

System.out.println("success"); // 请不要修改或删除

System.out.println("即时到账支付成功");

//给财付通系统发送成功信息，财付通系统收到此结果后不再进行后续通知

resHandler.sendToCFT("success");

//给微信服务器返回success 否则30分钟通知8次

return "success";

}else{

System.out.println("通知签名验证失败");

resHandler.sendToCFT("fail");

response.setCharacterEncoding("utf-8");

}

}else {

System.out.println("fail -Md5 failed");

如何使用微信sdk java版

1.首先我们新建一个Java开发包WeiXinSDK

2.包路径：com.ansitech.weixin.sdk

测试的前提条件：

假如我的公众账号微信号为：vzhanqun

我的服务器地址为：

下面我们需要新建一个URL的请求地址

我们新建一个Servlet来验证URL的真实性，具体接口参考

接入指南

3.新建com.ansitech.weixin.sdk.WeixinUrlFilter.java

这里我们主要是获取微信服务器法师的验证信息，具体验证代码如下

[java] view plain copy print?

package com.ansitech.weixin.sdk;

import com.ansitech.weixin.sdk.util.SHA1;

import java.io.IOException;

import java.util.ArrayList;

import java.util.Collections;

import java.util.Comparator;

import java.util.List;

import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

public class WeixinUrlFilter implements Filter {

//这个Token是给微信开发者接入时填的

//可以是任意英文字母或数字，长度为3-32字符

private static String Token = "vzhanqun1234567890";

@Override

public void init(FilterConfig config) throws ServletException {

System.out.println("WeixinUrlFilter启动成功!");

}

@Override

public void doFilter(ServletRequest req, ServletResponse res,

FilterChain chain) throws IOException, ServletException {

HttpServletRequest request = (HttpServletRequest) req;

HttpServletResponse response = (HttpServletResponse) res;

//微信服务器将发送GET请求到填写的URL上,这里需要判定是否为GET请求

boolean isGet = request.getMethod().toLowerCase().equals("get");

System.out.println("获得微信请求:" + request.getMethod() + " 方式");

if (isGet) {

//验证URL真实性

String signature = request.getParameter("signature");// 微信加密签名

String timestamp = request.getParameter("timestamp");// 时间戳

String nonce = request.getParameter("nonce");// 随机数

String echostr = request.getParameter("echostr");//随机字符串

ListString params = new ArrayListString();

params.add(Token);

params.add(timestamp);

params.add(nonce);

//1. 将token、timestamp、nonce三个参数进行字典序排序

Collections.sort(params, new ComparatorString() {

@Override

public int compare(String o1, String o2) {

return o1.compareTo(o2);

}

});

//2. 将三个参数字符串拼接成一个字符串进行sha1加密

String temp = SHA1.encode(params.get(0) + params.get(1) + params.get(2));

if (temp.equals(signature)) {

response.getWriter().write(echostr);

}

} else {

//处理接收消息

}

@Override

public void destroy() {

}

好了，不过这里有个SHA1算法，我这里也把SHA1算法的源码给贴出来吧！

4.新建com.ansitech.weixin.sdk.util.SHA1.java

[java] view plain copy print?

package com.ansitech.weixin.sdk.util;

import java.security.MessageDigest;

/**

public final class SHA1 {

private static final char[] HEX_DIGITS = {'0', '1', '2', '3', '4', '5',

'6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};

/**

* Takes the raw bytes from the digest and formats them correct.

* @param bytes the raw bytes from the digest.

* @return the formatted bytes.

private static String getFormattedText(byte[] bytes) {

int len = bytes.length;

StringBuilder buf = new StringBuilder(len * 2);

// 把密文转换成十六进制的字符串形式

for (int j = 0; j len; j++) {

buf.append(HEX_DIGITS[(bytes[j] 4) 0x0f]);

buf.append(HEX_DIGITS[bytes[j] 0x0f]);

}

return buf.toString();

}

public static String encode(String str) {

if (str == null) {

return null;

}

try {

MessageDigest messageDigest = MessageDigest.getInstance("SHA1");

messageDigest.update(str.getBytes());

return getFormattedText(messageDigest.digest());

} catch (Exception e) {

throw new RuntimeException(e);

}

5.把这个Servlet配置到web.xml中

[html] view plain copy print?

filter

description微信消息接入接口/description

filter-nameWeixinUrlFilter/filter-name

filter-classcom.ansitech.weixin.sdk.WeixinUrlFilter/filter-class

/filter

filter-mapping

filter-nameWeixinUrlFilter/filter-name

url-pattern/api/vzhanqun/url-pattern

/filter-mapping

好了，接入的开发代码已经完成。

6.下面就把地址URL和密钥Token填入到微信申请成为开发者模式中吧。
