使用Dictionary接收前端数据，并用反射更新对像数据
前端调用方式
wx.request({
url: app.globalData.serverHttpUrl + "/JoinTeam/UpdateLeader",
data: { TeamId: thisProxy.data.theTeam.TeamId, PlayerId: e.currentTarget.id },
method: 'PUT',
header: { 'Cookie': wx.getStorageSync('wxloginToken'),'content-type': 'application/x-www-form-urlencoded' },
success: (res) => {
console.log(res)
}
}）
