我是靠谱客的博主潇洒滑板，最近开发中收集的这篇文章主要介绍Java 实现微信公众号自定义功能开发-自定义菜单，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

首先：熟读https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421141013中自定义菜单创建接口，和自己的功能需求对比，确定后方能下一步。

第二步：确保自己的公众号已开通自定义菜单功能，

第三步：创建自定义菜单：

url：https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN

请求方式POST

包：

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.ConnectException;
import java.net.URL;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import net.sf.json.JSONException;
import net.sf.json.JSONObject;

service:

public static Stringmenu_create_url= "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN";

public static int createMenu(wMenu menu, String accessToken) {
int result = 0;
// 拼装创建菜单的url
String url = menu_create_url.replace("ACCESS_TOKEN", accessToken);
// 将菜单对象转换成json字符串
String jsonMenu = JSONObject.fromObject(menu).toString();
// 调用接口创建菜单
JSONObject jsonObject = httpRequest(url, "POST", jsonMenu);
if (null != jsonObject) {
if (0 != jsonObject.getInt("errcode")) {
result = jsonObject.getInt("errcode");
log.error("创建菜单失败errcode:{}errmsg:{}",jsonObject.getInt("errcode"), jsonObject.getString("errmsg"));
}
}
return result;

}

Util:

public static JSONObject httpRequest(String requestUrl, String requestMethod, String outputStr) {
JSONObject jsonObject = null;
StringBuffer buffer = new StringBuffer();
try {
// 创建SSLContext对象，并使用我们指定的信任管理器初始化
TrustManager[] tm = { new MyX509TrustManager() };
SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE");
sslContext.init(null, tm, new java.security.SecureRandom());
// 从上述SSLContext对象中得到SSLSocketFactory对象
SSLSocketFactory ssf = sslContext.getSocketFactory();
URL url = new URL(requestUrl);
HttpsURLConnection httpUrlConn = (HttpsURLConnection) url.openConnection();
httpUrlConn.setSSLSocketFactory(ssf);
httpUrlConn.setDoOutput(true);
httpUrlConn.setDoInput(true);
httpUrlConn.setUseCaches(false);
// 设置请求方式（GET/POST）
httpUrlConn.setRequestMethod(requestMethod);
if ("GET".equalsIgnoreCase(requestMethod))
httpUrlConn.connect();
// 当有数据需要提交时
if (null != outputStr) {
OutputStream outputStream = httpUrlConn.getOutputStream();
// 注意编码格式，防止中文乱码
outputStream.write(outputStr.getBytes("UTF-8"));
outputStream.close();
}
// 将返回的输入流转换成字符串
InputStream inputStream = httpUrlConn.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String str = null;
while ((str = bufferedReader.readLine()) != null) {
buffer.append(str);
}
bufferedReader.close();
inputStreamReader.close();
// 释放资源
inputStream.close();
inputStream = null;
httpUrlConn.disconnect();
jsonObject = JSONObject.fromObject(buffer.toString());
} catch (ConnectException ce) {
log.error("Weixin server connection timed out.");
} catch (Exception e) {
log.error("https request error:{}", e);
}
return jsonObject;

}

菜单实体：

public class wMenu extends BasicModel{
private List<ComplexButton> button;
public List<ComplexButton> getButton() {
return button;
}
public void setButton(List<ComplexButton> button) {
this.button = button;
}

}

一级菜单：

public class ComplexButton extends Button{
private Integer ComplexId;
private String url;
private List<CommonButton> sub_button;

}

二级菜单：

public class CommonButton extends Button {
private Integer CommonId ;

private String parentName;

}

token 获取

public final static String access_token_url = "https://api.weixin.qq.com/cgi-bin/token"

public static AccessToken getAccessToken(String appid, String appsecret) {
AccessToken accessToken = null;
String requestUrl = access_token_url.replace("APPID", appid).replace("APPSECRET", appsecret);
JSONObject jsonObject = httpRequest(requestUrl, "GET", null);
// 如果请求成功
if (null != jsonObject) {
try {
accessToken = new AccessToken();
accessToken.setToken(jsonObject.getString("access_token"));
accessToken.setExpiresIn(jsonObject.getInt("expires_in"));
} catch (JSONException e) {
accessToken = null;
// 获取token失败
log.error("获取token失败 errcode:{} errmsg:{}", jsonObject.getInt("errcode"),
jsonObject.getString("errmsg"));
}
}
return accessToken;
