微信公众号支付(一)如何获取用户openId
一、获取apikey,appsecret与商户号
二、获取用户的OpenId
1.设置【授权回调页面域名】
2.用户同意授权
我是把这个url写在微信菜单下的,当进入这个页面的时候就让用户同意。注意:好像是静默授权的,用户不知道
1.url:
https://open.weixin.qq.com/connect/oauth/authorize?appid=appid&redirect_uri=url&response_type=code&scope=snsapi_userinfo&state=park#wechat_redirect
redirect_uri:重定向的url,就是授权后要跳转的页面
scope:应用授权作用域
snsapi_base:不弹出授权页面,直接跳转,只能获取用户openid
snsapi_userinfo:弹出授权页面,可通过openid拿到昵称、性别、所在地
state:重定向后带的参数
2.用户同意后会产生一个code,只有分钟时间的有效期。
String code = request.getParameter("code")
3.code换openId
/**
* 常量类
* @author rory.wu

*/
public class Constants {
// 第三方用户唯一凭证
public static String appid = "";
// 第三方用户唯一凭证密钥
public static String appsecret = "";
//商户ID
public static String mch_id="";
//获取openId
public static String oauth_url = "https://api.weixin.qq.com/sns/oauth/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code";
}
/**
* 通用工具类
* @author rory.wu
* @version .
* @since 年月日
*/
public class CommonUtil {
private static Logger log = Logger.getLogger(CommonUtil.class);
public static jsONObject httpsRequestToJsonObject(String requestUrl, String requestMethod, String outputStr) {
JSONObject jsonObject = null;
try {
StringBuffer buffer =FKwnxV httpsRequest(requestUrl, requestMethod, outputStr);
jsonObject = JSONObject.fromObject(buffer.toString());
} catch (ConnectException ce) {
log.error("连接超时:"+ce.getMessage());
} catch (Exception e) {
log.error("https请求异常:"+e.getMessage());
}
return jsonObject;
}
private static StringBuffer httpsRequest(String requestUrl, String requestMethod, String output)
throws NoSuchAlgorithmException, NoSuchProviderException, KeyManagementException, MalformedURLException,
IOException, ProtocolException, UnsupportedEncodingException {
URL url = new URL(requestUrl);
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setUseCaches(false);
connection.setRequestMethod(requestMethod);
if (null != output) {
OutputStream outputStream = connection.getOutputStream();
outputStream.write(output.getBytes("UTF-"));
outputStream.close();
}
// 从输入流读取返回内容
InputStrFKwnxVeam inputStream = connection.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-");
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String str = null;
StringBuffer buffer = new StringBuffer();
while ((str = bufferedReader.readLine()) != null) {
buffer.append(str);
}
bufferedReader.close();
inputStreamReader.close();
inputStream.close();
inputStream = null;
connection.disconnect();
return buffer;
} }
/**
* 获取用户的openId,并放入session
* @param code 微信返回的code
*/
private void setOpenId(String code) {
session.put("code", code);
String oauth_url = Constants.oauth_url.replace("APPID", Constants.appid).replace("SECRET", Constants.appsecret).replace("CODE", String.valueOf(session.get("code")));
log.info("oauth_url:"+oauth_url);
JSONObject jsonObject = CommonUtil.httpsRequestToJsonObject(oauth_url, "POST", null);
log.info("jsonObject:"+jsonObject);
Object errorCode = jsonObject.get("errcode");
if(errorCode != null) {
log.info("code不合法");
}else{
String openId = jsonObject.getString("openid");
log.info("openId:"+openId);
session.put("openId", openId);
}
}
oauth_url返回的格式是:
{
"access_token":"ACCESS_TOKEN",
"expires_in":,
"refresh_token":"REFRESH_TOKEN",
"openid":"OPENID", "scope":"SCOPE",
"unionid": "o_bmasdasdsad_sgVthMZOPfL"
}
Code无效时:
{
FKwnxV "errcode":
,"errmsg":"invalid code"
}
