SOAP 请求因错误而失败 验证消息的安全性时发生错误

Question

被 SOAP 请求困住了。

我用来发出请求的代码：

def get_body():
    import datetime
    today_datetime = datetime.datetime.today() - datetime.timedelta(minutes=1)
    expires_datetime = today_datetime + datetime.timedelta(minutes=5)
    body = """

    body = body.format(uuid.uuid4(), uuid.uuid4(), today_datetime.strftime("%Y-%m-%dT%H:%M:%SZ"), expires_datetime.strftime("%Y-%m-%dT%H:%M:%SZ"), uuid.uuid4())
    return body

headers = {"content-type" : "text/xml"}
res = requests.post(url, data=get_body(), headers=headers)

我使用的凭据是正确的，但请求仍然失败。

我在这里遗漏了一些标题吗？
