uniapp/微信小程序获取手机号

在获取手机号需要让用户进行登录获取session_key进行解密的

首先需要让用户进行登录



uniapp



<button type=”primary” class=”weixin” style=”height: 83rpx;text-align: center;line-height: 83rpx;padding: 0;font-size: 30rpx;” open-type=”getUserInfo” @getuserinfo=”onLogin”>
        微信快速登录
      </button>




uni.showLoading({
        title: ‘登陆中…’
      });
      //获取用户基本信息
      let logInfo = {};
      let that = this;
      uni.login({
        provider: ‘weixin’,
        success: function(loginRes) {
          logInfo.code = loginRes.code;
          uni.getUserInfo({
            provider: ‘weixin’,
            success: function(infoRes) {
              logInfo.nickName = infoRes.userInfo.nickName;
              logInfo.avatarUrl = infoRes.userInfo.avatarUrl;
              uni.hideLoading();
              that.loginfo = logInfo;
  //这里获取到登录code,从而去换取openid与session_key
              login(‘mobile’, logInfo.code, logInfo.nickName)
                .then(res => {
                  if (res.code != 0) {
                    //登录失败，接口返回错误信息
                    uni.showModal({
                      title: ‘提示’,
                      content: res.msg,
                      showCancel: false,
                      success: function(res) {}
                    });
                  } else if (res.msg == ‘未授权手机号’) {
                    that.loginfo.sessionkey = res.data.sessionkey;
                    that.loginfo.openid = res.data.openid;
                    that.show = true
                  } else {
                    // 登录成功
                    uni.showModal({
                      title: ‘提示’,
                      content: res.msg,
                      showCancel: false,
                      success: function(res) {
                        uni.navigateBack({ delta: 1 });
                      }
                    });
                  }
                })
                .catch(err => {
                  console.log(err);
                  uni.showModal({
                    title: ‘提示’,
                    content: ‘登录失败，请检查网络’,
                    showCancel: false,
                    success: function(res) {}
                  });
                });
            },
            fail: function(res) {
              uni.hideLoading();
              uni.showModal({
                title: ‘提示’,
                content: ‘获取登录所需的随机用户标识失败’,
                showCancel: false,
                success: function(res) {}
              });
            }
          });
        },
        fail: function(res) {
          uni.hideLoading();
          uni.showModal({
            title: ‘提示’,
            content: ‘获取基本信息失败’,
            showCancel: false,
            success: function(res) {}
          });
        }
      });

后端(PHP进行处理)



$strUrl = “https://api.weixin.qq.com/sns/jscode2session?appid=” . ‘AppId’ . “&secret=” . “Select”. “&js_code=” . “用户CODE” . “&grant_type=authorization_code”;
                    $strCurlRequest = curlRequest($strUrl);
                    if (!$strCurlRequest[‘ok’]) result([], 1, ‘从微信获取用户唯一标识失败’);
                    $arrCurlData = array();
                    $isErr = false;
                    try {
                        $arrCurlData = json_decode($strCurlRequest[‘data’], true);
                    } catch (\Throwable $e) {
                        $isErr = true;
                    }

这里获取到了openid与session_key,将其保存回来之后进行申请手机号操作





<button
                  class=”weixin”
                  style=”text-align: center;line-height: 73rpx;height: 73rpx;padding: 0;font-size: 30rpx;”
                  open-type=”getPhoneNumber”
                  @getphonenumber=”getPhoneNumber”
                >
                  手机号授权
                </button>




 getPhoneNumber(e) {
      if (‘getPhoneNumber:ok’ != e.detail.errMsg) {
        uni.showModal({
          title: ‘提示’,
          content: ‘手机号授权获取失败!’,
          showCancel: false,
          success: function(res) {}
        });
      } else {
        login(‘mobile’, this.loginfo.code, this.loginfo.nickName, {
          iv: e.detail.iv,
          encryptedData: e.detail.encryptedData,
          sessionkey: this.loginfo.sessionkey,
          openid: this.loginfo.openid
        })
          .then(res => {
            if (res.code != 0) {
              //登录失败，接口返回错误信息
              uni.showModal({
                title: ‘提示’,
                content: res.msg,
                showCancel: false,
                success: function(res) {}
              });
            }else {
              // 登录成功
              uni.showModal({
                title: ‘提示’,
                content: res.msg,
                showCancel: false,
                success: function(res) {
                  uni.navigateBack({ delta: 1 });
                }
              });
            }
          })
          .catch(err => {
            console.log(err);
            uni.showModal({
              title: ‘提示’,
              content: ‘登录失败，请检查网络’,
              showCancel: false,
              success: function(res) {}
            });
          });
      }
    },

获取到encryptedData,sessionkey后进行解密


//解密手机号
                    if (strlen($strSessionKey) != 24) {
                        result([], 1, “获取手机号授权密匙错误,请重试!”);
                    }
                    $aesKey = base64_decode($strSessionKey);//session_key
                    if (strlen($strIv) != 24) {
                        result([], 1, “获取手机号授权校验错误,请重试!”); //IV
                    }
                    $aesIV = base64_decode($strIv);
                    $aesCipher = base64_decode($strEncryptedData);
                    $result = openssl_decrypt($aesCipher, “AES-128-CBC”, $aesKey, 1, $aesIV);
                    $dataObj = json_decode($result);
                    if ($dataObj  == NULL) {
                        result([], 1, “获取手机号授权解密错误,请重试!”);
                    }
                    if ($dataObj->watermark->appid != “APPID”) {
                        result([], 1, “获取手机号授权解密错误,请重试!”);
                    }
                    $arrResult = [];
                    try {
                        $arrResult = json_decode($result, true);
                    } catch (\Throwable $e) {
                        result([], 1, “获取手机号授权解密错误,请重试!”);
                    }

解密后就可以获取到手机号了
