我是靠谱客的博主纯情飞鸟，最近开发中收集的这篇文章主要介绍JAVA 实现微信公众号菜单设置功能，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

接上前边微信的相关功能，本编实现的功能为使用JAVA代码设置微信公众号菜单。

请求外链接方法

public static String AccessUrl(String url, String postString) {

OutputStream os = conn.getOutputStream();
os.write(postString.getBytes("UTF-8")); // 往远程URL传递参数
os.flush();
os.close();
int code = conn.getResponseCode();
conn.getHeaderFields();
conn.getContentLength();
if (code == 200) {// 返回成功
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));
String line;
StringBuffer buffer = new StringBuffer();
while ((line = reader.readLine()) != null) {

} else {
logger.error("返回失败：" + code);
}
} catch (MalformedURLException e) {

}finally{
