这个错误一般是因为请求中的某个参数值不是字典类型而导致的。请检查 payload 参数是否正确构造为字典类型。你可以尝试将 payload 参数中的 JSON 字符串转换为字典类型，如下所示：

import requests

url = "https://crm.baidu.com/polaris-web/sme-cust/verify/verifyName"

payload = {"name": "三本树（上海）教育科技有限公司"}

headers = {
    "isajax": "true",
    "Cookie": "BIDUPSID=A09C98D9802D21EDCE9B8A4490EC5CE2; PSTM=1684252632; BAIDUID=A09C98D9802D21ED17765F505D625969:FG; BAIDUID_BFESS=A09C98D9802D21ED17765F505D625969:FG; ZFY=qt8fKnqLflisaA:BUnKqV:Awo8rk7t:AVWJCPMo5050PfU:C; HR_SIGN=UC_70a2711cf0144243891424851662987554571; Hm_lpvt_2188c29772eeba07a9fce63dc27d321c=1685026331; RT=\"z; tk=313027c567ba2913015e3f047346a9b2-1685026351022",

    "Content-Type": "application/json;charset=UTF-8",
}

response = requests.post(url, headers=headers, json=payload)

print(response.text)
