获取scheme码： $data        = [
    "jump_wxa"    => [
        "path"  => "pages/startPage/startPage",
        "query" => `mobile={$user_mobile}&password={$password}`
    ],
    "expire_type" => 0,
];

小程序接收参数代码： let obj = wx.getLaunchOptionsSync();

    let params = obj.query

    if (params.mobile != undefined) {

      mobile = params.mobile

    }

    if (params.password != undefined) {

      password = params.password

    }

let loginparams = {

          type: 1,

          mobile,

          password

}

this.login(loginparams)
