微信公眾號建立自定義選單(公眾號跳轉小程式功能)
使用JAVA後端去自定義建立選單，微信公眾號開發文件中提供了API:
建立選單中有一些要注意的地方:
1、自定義選單最多包括3個一級選單，每個一級選單最多包含5個二級選單。
2、一級選單最多4個漢字，二級選單最多7個漢字，多出來的部分將會以“...”代替。
3、建立自定義選單後，選單的重新整理策略是，在使用者進入公眾號會話頁或公眾號profile頁時，如果發現上一次拉取選單的請求在5分鐘以前，就會拉取一下選單，如果選單有更新，就會重新整理客戶端的選單。測試時可以嘗試取消關注公眾賬號後再次關注，則可以看到建立後的效果。
這些可以說是建立選單中的格式或者是規則,下面是選單的型別，每個型別代表給他建立的選單中的功能是不一樣的，請認真檢視文件
程式碼例項:
HttpUtils.java(傳送POST請求)：
import com.alibaba.fastjson.JSONObject;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.io.IOException;
import java.net.URLDecoder;
/**
* <p>User: qrn
* <p>Date: 14-1-28
* <p>Version: 1.0
* 描述: http請求的工具類
*/
public class HttpUtils {
private static Logger logger = LoggerFactory.getLogger(HttpUtils.class); //日誌記錄
/**
* httpPost
*
* @param url 路徑
* @param jsonParam 引數
* @return JSONObject
*/
public static JSONObject httpPost(String url, String jsonParam) {
return httpPost(url, jsonParam, false);
}
/**
* post請求
*
* @param url url地址
* @param param 引數
* @param noNeedResponse 不需要返回結果
* @return JSONObject
*/
public static JSONObject httpPost(String url, String param, boolean noNeedResponse) {
//post請求返回結果
HttpClient httpClient = HttpClients.createDefault();
JSONObject jsonResult = null;
HttpPost method = new HttpPost(url);
try {
if (null != param) {
//解決中文亂碼問題
StringEntity entity = new StringEntity(param, "utf-8");
entity.setContentEncoding("UTF-8");
entity.setContentType("application/json");
method.setEntity(entity);
}
HttpResponse result = httpClient.execute(method);
url = URLDecoder.decode(url, "UTF-8");
/**請求傳送成功，並得到響應**/
if (result.getStatusLine().getStatusCode() == 200) {
String str = "";
try {
/**讀取伺服器返回過來的json字串資料**/
str = EntityUtils.toString(result.getEntity());
System.out.println(str);
if (noNeedResponse) {
return null;
}
/**把json字串轉換成json物件**/
jsonResult = JSONObject.parseObject(str);
} catch (Exception e) {
logger.error("post請求提交失敗:" + url, e);
}
}
} catch (IOException e) {
logger.error("post請求提交失敗:" + url, e);
}
return jsonResult;
}
}
建立選單的方法(SpringMvc)：
/**
* 建立自定義選單:
*/
@RequestMapping("/getAccount_txt")
@ResponseBody
public void getAccount_txt() {
String access_token = accountsService.Accountaccess_token(); //這裡是獲取的TOken介面
String url=WeChatTools.create+access_token; //這裡是建立選單的介面和token拼接 https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN
System.out.println("傳送的url"+url);
String sun="{\r\n" +
" \"button\":[\r\n" +
" { \r\n" +
" \"type\":\"click\",\r\n" +
" \"name\":\"今日歌曲\",\r\n" +
" \"key\":\"V1001_TODAY_MUSIC\"\r\n" +
" },\r\n" +
" {\r\n" +
" \"name\":\"選單\",\r\n" +
" \"sub_button\":[\r\n" +
" { \r\n" +
" \"type\":\"view\",\r\n" +
" \"name\":\"搜尋\",\r\n" +
" \"url\":\"http://www.soso.com/\"\r\n" +
" },\r\n" +
" {\r\n" +
" \"type\":\"miniprogram\",\r\n" +
" \"name\":\"wxa\",\r\n" +
" \"url\":\"http://mp.weixin.qq.com\",\r\n" +
" \"appid\":\"wx286b93c14bbf93aa\",\r\n" +
" \"pagepath\":\"pages/lunar/index\"\r\n" +
" },\r\n" +
" {\r\n" +
" \"type\":\"click\",\r\n" +
" \"name\":\"贊一下我們\",\r\n" +
" \"key\":\"V1001_GOOD\"\r\n" +
" }]\r\n" +
" }]\r\n" +
" }";
JSONObject jsonObjects=JSONObject.fromObject(sun);
HttpUtils.httpPost(url,jsonObjects.toString());
}
這樣根據自己所需要的去拼寫相應的型別就可以實現了
下面是進行了封裝的建立選單：

這裡就是建立自定義選單的例項了，這些程式碼應該是沒有問題的，如果有問題可以在下發評論
