微信公众号开发 - 15.用户管理获取基本用户资料
前言
如果用户授权后我们拿到他的openid,就可以直接查询他的资料了,上篇文章我们就拿到了用户的openid,这里就可以直接使用。 :grin:
因为之前用使用的是httpclient来提交返回数据,而微信公众平台的接口都是基于https协议,所以这里我们重新做一下https的封装。

获取资料
/**

* @return
*/
public static WeixinUserInfo getUserInfo(String accessToken, String openId) {

// 拼接请求地址

HTTPS封装
信任管理器
package cn.notemi.util;
import javax.net.ssl.X509TrustManager;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
/**
* Title:MyX509TrustManager
* Description:信任管理器
*
* @author Flicker
* @create 2017-07-28 下午 1:45
**/
public class MyX509TrustManager implements X509TrustManager {
// 检查客户端证书
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
// 检查服务器端证书
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
// 返回受信任的X509证书数组
public X509Certificate[] getAcceptedIssuers() {
return null;
}
}
https请求方法
/**
* 发送https请求
*
* @param requestUrl 请求地址
* @param requestMethod 请求方式(GET、POST)
* @param outputStr 提交的数据
* @return JSONObject(通过JSONObject.get(key)的方式获取json对象的属性值)
*/
public static JSONObject httpsRequest(String requestUrl, String requestMethod, String outputStr) {
JSONObject jsonObject = null;
try {
// 创建SSLContext对象,并使用我们指定的信任管理器初始化
TrustManager[] tm = { new MyX509TrustManager() };
SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE");
sslContext.init(null, tm, new java.security.SecureRandom());
// 从上述SSLContext对象中得到SSLSocketFactory对象
SSLSocketFactory ssf = sslContext.getSocketFactory();
URL url = new URL(requestUrl);
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setSSLSocketFactory(ssf);
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
// 设置请求方式(GET/POST)
conn.setRequestMethod(requestMethod);
// 当outputStr不为null时向输出流写数据
if (null != outputStr) {
OutputStream outputStream = conn.getOutputStream();
// 注意编码格式
outputStream.write(outputStr.getBytes("UTF-8"));
outputStream.close();
}
// 从输入流读取返回内容
InputStream inputStream = conn.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String str = null;
StringBuffer buffer = new StringBuffer();
while ((str = bufferedReader.readLine()) != null) {
buffer.append(str);
}
// 释放资源
bufferedReader.close();
inputStreamReader.close();
inputStream.close();

conn.disconnect();
jsonObject = JSONObject.fromObject(buffer.toString());
} catch (ConnectException ce) {
logger.error("连接超时:{}", ce);
