MIME多部分流的意外结束。 MIME多部分消息未完成

Question

我尝试使用mime / multipart请求构建一个由多个子请求组成的http请求。这是我的客户代码：

def build_request( url, type, headers, data = {}):

    request = MIMEBase("application", "http")

    #Build appropriate request
    if type == "get":
        request.data = Request('GET', url, headers=headers)

    elif type == "post":
        request.data = Request('POST', url, data = json.dumps(data), headers = {'Content-Type':'application/http'})

    elif type == "delete":
        request.data = Request('DELETE', url, headers = {'Content-Type':'application/http'})

    elif type == "put":
        request.data = Request('PUT', url, data = json.dumps(data), headers = {'Content-Type':'application/http'})

    elif type == "patch":
        request.data = Request('PATCH', url, data = json.dumps(data), headers = {'Content-Type':'application/http'})

    return request

if __name__ == '__main__':

    url = "http://localhost:65200/api";

    #Get customers
    get_customers = build_request( url + "/Customers", "get", headers)

    #Add a customer
    add_customer = build_request( url + "/Customers", "post", data=added_customer, headers=headers)

    #update a customer
    update_customer = build_request( url + "/Customers/{0}".format(updated_customer["Id"]), "put", data=updated_customer, headers=headers)

    #Remove a customer
    remove_customer = build_request( url + "/Customers/{0}".format(removed_customer["Id"]), "delete", headers=headers)

    s = Session()

    uuid = uuid.uuid4()

    message = MIMEMultipart("mixed", "batch_{0}".format(uuid), [get_customers,add_customer,update_customer,remove_customer])

    headers = {'Content-Type':'multipart/mixed; boundary=\"{0}\"'.format(uuid)}


    #Error here    
    reply = requests.post(url + "/batch", data = message.as_string(), headers=headers)

错误：

有人知道如何解决这个问题吗？
