1. Foreword

Usually in the process of developing WeChat, we will definitely design the use of WeChat-related menus. This time I will introduce to you how to use weixin-java-tools to manage the menu

2. Custom menu classification

1. Click: Click push event After the user clicks the click type button, the WeChat server will push the message type event structure to the developer through the message interface (refer to the message interface Guide), and bring the key value filled in by the developer in the button.

　Please note that all events from 3 to 8 only support WeChat iPhone 5.4.1 or above, and WeChat users with Android 5.4 or above. WeChat users with older versions will not respond after clicking. , developers cannot receive event push normally. 9 and 10 are event types specially prepared for subscription accounts of third-party platforms that have not been certified by WeChat (specifically, those who have failed to pass the qualification certification). They do not have event push and their capabilities are relatively limited. Other types of public accounts No need to use.

3. Calling interface address: http Request method: POST (please use https protocol) https://api.weixin.qq.com/ cgi-bin/menu/create?access_token=ACCESS_TOKEN

六、代碼實現(xiàn)：

package com.weixin.menu;

import java.util.ArrayList;
import java.util.List;

import me.chanjar.weixin.common.bean.WxMenu;
import me.chanjar.weixin.common.bean.WxMenu.WxMenuButton;
import me.chanjar.weixin.common.exception.WxErrorException;
import me.chanjar.weixin.mp.api.WxMpInMemoryConfigStorage;
import me.chanjar.weixin.mp.api.WxMpService;
import me.chanjar.weixin.mp.api.WxMpServiceImpl;

public class WeixinMenuService {

	public static void main(String[] args) {
		
		//創(chuàng)建菜單
		//創(chuàng)建一級菜單
		WxMenuButton button1=new WxMenuButton();
		button1.setType("click"); //點擊事件按鈕
		button1.setName("點擊菜單");
		button1.setKey("key1"); //根據(jù)標(biāo)志獲取點擊菜單
		
		//創(chuàng)建一個復(fù)合菜單
		WxMenuButton button2=new WxMenuButton();
		button2.setName("多級菜單");
		
		WxMenuButton button2_1=new WxMenuButton();
		button2_1.setType("click"); //點擊事件按鈕
		button2_1.setName("子菜單一");
		button2_1.setKey("key2"); //根據(jù)標(biāo)志獲取點擊菜單
		
		WxMenuButton button2_2=new WxMenuButton();
		button2_2.setType("click"); //點擊事件按鈕
		button2_2.setName("子菜單二");
		button2_2.setKey("key3"); //根據(jù)標(biāo)志獲取點擊菜單
		
		
		WxMenuButton button3=new WxMenuButton();
		button3.setName("url菜單");
		button3.setType("view");
		button3.setUrl("http://www.baidu.com");  //必須添加http
		
		
		List<WxMenuButton> subButtons=new ArrayList<WxMenuButton>();
		subButtons.add(button2_1);
		subButtons.add(button2_2);
		button2.setSubButtons(subButtons);
		
		List<WxMenuButton> buttons=new ArrayList<WxMenuButton>();
		buttons.add(button1);
		buttons.add(button2);
		buttons.add(button3);
		
		WxMenu menu=new WxMenu();
		menu.setButtons(buttons);
		
		
		//發(fā)送請求 創(chuàng)建菜單
		WxMpService service=new WxMpServiceImpl();	
		WxMpInMemoryConfigStorage wxConfigProvider=new WxMpInMemoryConfigStorage();
		wxConfigProvider.setAppId("wx60a8f1c3a95b0b9c");
		wxConfigProvider.setSecret("5b0e8613b538da5ac4bbc610998f10ba");
		service.setWxMpConfigStorage(wxConfigProvider);
		try {
			service.menuCreate(menu);
		} catch (WxErrorException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}


	}

}

七、點擊菜單事件推送

　　7.1 消息格式

<xml>
<ToUserName><![CDATA[toUser]]></ToUserName>
<FromUserName><![CDATA[FromUser]]></FromUserName>
<CreateTime>123456789</CreateTime>
<MsgType><![CDATA[event]]></MsgType>
<Event><![CDATA[CLICK]]></Event>
<EventKey><![CDATA[EVENTKEY]]></EventKey>
</xml>

　　7.2 參數(shù)說明

　　7.3 消息處理

　　在接收消息的post中判斷消息類型 并做相關(guān)處理。

//獲取消息流
		WxMpXmlMessage message=WxMpXmlMessage.fromXml(request.getInputStream());
		
		if(message.getMsgType().equals("event")){ //事件
			
			//判斷event
			if(message.getEvent().equals("click") && message.getEventKey().equals("key1")){
				//do something
				
			}
			
			
		}
