小程序获取openid 获取绑定手机号，获取unionid
//根据code换取用户openId
@SuppressWarnings({"static-access", "resource"})
@RequestMapping(value = "getOpenId")
public JSONObject getOpenId(HttpServletRequest request, HttpServletResponse response) {
try {
response.setHeader("Access-Control-Allow-Origin", "*");
String appid ="";//appid
String secret ="";//密钥
String code = request.getParameter("code");
if (!StringUtils.isBlank(appid)) {
String url = "https://api.weixin.qq.com/sns/jscode2session?appid=" + appid + "&secret=" + secret
+ "&js_code=" + code + "&grant_type=authorization_code";
HttpClient client = new DefaultHttpClient();
// 发送get请求

HttpResponse res = client.execute(req);
String strResult = "";

}
JSONObject jsonObj = new JSONObject();
jsonObj = new JSONObject().parseObject(strResult);

}获取绑定手机号
@ResponseBody
@RequestMapping(value = "decodeUserInfo", method = RequestMethod.POST)
public Map decodeUserInfo(String encryptedData, String iv, String session_key) {
Map map = new HashMap();
//小程序唯一标识 (在微信小程序管理后台获取)
String wxspAppid = "";
//小程序的 app secret (在微信小程序管理后台获取)
String wxspSecret = "";
//授权（必填）
String grant_type = "authorization_code";
1、向微信服务器 使用登录凭证 code 获取 session_key 和 openid
//请求参数
String params = "appid=" + wxspAppid + "&secret=" + wxspSecret + "&js_code=" + code + "&grant_type=" + grant_type;
//发送请求
String sr = HttpRequest.sendGet("https://api.weixin.qq.com/sns/jscode2session", params);
//解析相应内容（转换成json对象）
JSONObject json = JSONObject.parseObject(sr);
//获取会话密钥（session_key）
String session_key = json.get("session_key").toString();
//用户的唯一标识（openid）
String openid = (String) json.get("openid");
2、对encryptedData加密数据进行AES解密
try {
String result = AesUtil.decrypt(encryptedData, session_key, iv, "UTF-8");
if (null != result && result.length() > 0) {
map.put("status", 1);
map.put("msg", "解密成功");
JSONObject userInfoJSON = JSONObject.parseObject(result);
Map userInfo = new HashMap();
userInfo.put("openId", openId);
userInfo.put("phoneNumber", userInfoJSON.get("phoneNumber"));
map.put("userInfo", userInfo);
return map;
}
} catch (Exception e) {
e.printStackTrace();
}
map.put("status", 0);
map.put("msg", "解密失败");
return map;
}获取unionid
@ResponseBody
@RequestMapping(value = "/decodeUserInfo", method = RequestMethod.POST)
public Map decodeUserInfo(String encryptedData, String iv, String code) {
Map map = new HashMap();
//登录凭证不能为空
if (code == null || code.length() == 0) {
map.put("status", 0);
map.put("msg", "code 不能为空");
return map;
}
//小程序唯一标识 (在微信小程序管理后台获取)
String wxspAppid = "";
//小程序的 app secret (在微信小程序管理后台获取)
String wxspSecret = "";
//授权（必填）
String grant_type = "authorization_code";
1、向微信服务器 使用登录凭证 code 获取 session_key 和 openid

//发送请求
String sr = HttpRequest.sendGet("https://api.weixin.qq.com/sns/jscode2session", params);
//解析相应内容（转换成json对象）
