使用

注入wechat

letmch=WechatConfiguare.MCH(mchId:"you mchId", secret:"your mch secret") // 如果不需要使用微信支付，这个可以设为nilletwechatConfig=tryWechatConfiguare(appId:"your appid", appSecret:"your app secret", mch: mch)        app.wechat.use(wechatConfig)

微信授权

获取 access token

try req.wechat.fetchUserAccessToken(code)

获取用户信息

try req.wechat.getUserInfo(access: atk, openId: openid)

通过code直接获取用户信息示例

try req.wechat.fetchUserAccessToken(code).flatMapThrowing({(tokenModel)iniflet errmsg= tokenModel.isErrMsg{throwRespError(err:.normal, msg: errmsg)}guardlet atk= tokenModel.accessTokenelse{throwRespError(err:.normal, msg:"access token is not exists")}guardlet openid= tokenModel.openIdelse{throwRespError(err:.normal, msg:"openid is not exists")}returntry req.wechat.getUserInfo(access: atk, openId: openid).encodeResponse(for: req)}).flatMap{ $0}

刷新 access token

try req.wechat.refresh(access: token)

验证access token是否有效

        req.wechat.valid(access: token, openId: openId)
