0，https://mp.weixin.qq.com/wiki?,官网地址T=resource/res_main1，获取客户信息:获取客户信息主要包括微信网页授权和UnionID机制(关注后获取)。先说网页授权方式1.1，引导授权地址。要获得代码授权，需要使用oauth2认证。首先，你需要引导客户打开地址。格式如下:https://open.weixin.qq.com/connect/oauth2/authorize? APPID = APPID & amp；重定向URI & amp；代码& amp范围=范围& ampState=State#wechat_redirect其中SCOPE为授权范围(snsapi _ userinfo)，STATE为参数，可以通过STATE传递，也可以通过传统的url拼接传递(需要编码)。REDIRECT_URL是授权后的回调地址。授权后，微信会跳转到带代码的REDIRECT_URL。例如:https://open.weixin.qq.com/connect/oauth2/authorize? appid = * * * * & amp；redirect _ uri = * * * * & amp代码& ampscope = snsapi _ userinfo & ampState=#wechat_redirect1.2，交换access_token和openid的代码来请求微信接口:https://api.weixin.qq.com/sns/oauth2/access_token? APPID = APPID & amp；秘密=秘密& amp代码=代码& ampGrant_type=authorization_code微信会返回令牌(该令牌只用于步骤4获取userinfo，与其他令牌不同)，该接口会返回openid、Access令牌、openid和refresh _ token；1.3刷新access_token(可选)如果accesstoken过期，可以通过refresh_token刷新令牌；请求是:https://api.weixin.qq.com/sns/oauth2/refresh_token?. APPID = APPID & amp；授权类型=刷新令牌& amp刷新令牌=刷新令牌；1.4拉客户信息(范围应该是snsapi_userinfo)。微信接口https://api.weixin.qq.com/sns/userinfo? ACCESS _ TOKEN = ACCESS _ TOKEN & amp；openid = OPENID & amplang = zh _ CN代码如下://https://API . weixin .

ACCESS _ TOKEN = ACCESS _ TOKEN & amp；openid = OPENID & amplang = zh _ CN该接口返回的订阅属性为是否被关注，0未被关注，1被关注，如果被关注，则返回头像等客户信息，如果未被关注，则不返回客户信息，返回的数据如图所示:image.png代码如下:公共静态图< String，String & gtgetAccessUserInfo(String openId){ String result = weixin util . connectweixin interface(String . format(Constant。URL.USER_INFO，getAccessToken()，openId)，" ")；返回JSON.parseObject(result，map . class)；}公共静态字符串getAccessToken(){ String result = weixin util . connectweixin interface(String . format(Constant。URL.ACCESS_TOKEN_URL，常量。WEIXIN.APP_ID，常量。WEIXIN.SECRET)、“)；JSON object JSON = JSON object . from object(result)；string token = strutil . getnotnullstrvalue(JSON . get(" access _ token "))；返回令牌；}一般来说，UnionID机制在获取客户信息方面有局限性。比如参数需要openid，如果不关注返回的数据，就无法获取客户信息；但通过UnionID获取客户信息更容易；需要匹配场景平衡；3.发送模板消息3.1以获取openid。此步骤与Unionid机制获取accesstoken3.2发送模板消息的步骤相同。首先在微信官方账号中配置模板ID如图:image.png部分代码如下:公共类notify template { private string template _ ID；私有字符串用户；私有字符串url私有字符串优先；私有字符串关键字1；私有字符串keyword2私有字符串关键字3；私有字符串关键字4；私有字符串关键字5；私有字符串备注；私有字符串颜色；public notify template(){ super()；} public notify template(String template _ id，String touser，String url，String first，String keyword1，String keyword2，String remark){ super()；this.template_id =模板_ id；this.touser = touserthis.url = urlthis.first = firstthis . keyword 1 = keyword 1；this . keyword 2 = keyword 2；this.remark =备注；this.color = " # 173177} }公共静态地图& ltString，String & gtsendTemplateMsg(notify template template){ String msg = template . tojsonmsg()；string result = weixin util . connectweixin interface(string . format(常量。URL.TEMPLATE_SEND_URL，getAccessToken())，msg)；JSON object obj = JSON object . from object(result)；地图& ltString，String & gtmap = JSONObject.toBean(obj，map . class)；log . info(" getsnsoauth 2 accessstoken = = & gt；{} "，地图)；返回地图；}
