微信公众号开发 - 15.用户管理获取基本用户资料

目录

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。 icon_biggrin.png

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。

HTTPS封装

信任管理器

package cn.notemi.util;

/**
 * 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

/**

     *
     * @param requestUrl 请求地址
     * @param requestMethod 请求方式(GET、POST)
     * @param outputStr 提交的数据

            inputStream = null;
            conn.disconnect();

        } catch (ConnectException ce) {
