python爬蟲,接口是post請求,參數是request payload 的形式,如何傳參

 

    payload = {
        "tmpFdt": eta,
        "tmpNacd": pol_code_ex,
        "tmpPod": tmpPod,
        "tmpPol": tmpPol
    }

    # 傳json格式的參數
    jdata = json.dumps(payload)
　　

    res = session.post(t_url, timeout=20, data=jdata, headers=headers)
