python - 无法使用 json.dumps() 将字典写入 python 文件

Question

我从 JSON 转储中收到响应，并且尝试将其加载到 log.txt 文件中，但这不会打印出任何内容

我的功能

def get_customer_last_action_executed(self):
    """
    Get the customer last action executed
    By inputing the CustomerID
    :return:
    """
    payload ={'customerID': self.CustomerID}
    if not self.CustomerID:
        customer_id = raw_input("Please  provide the customer ID:")
        self.CustomerID = customer_id
        # raise Exception('No customerID provided')

    response = self.send_request(self.get_customer_last_action_executed_url + self.CustomerID,
                                 json.dumps(payload),
                                 "GET")

    print response.url, response.status_code
    print response, response.text, response.reason
    if response:
        print self.sucessful_msg
    else:
        print self.error_msg
    with open('log.txt', 'w') as f:
        json.dumps(payload, f)

Answer 1

您需要使用的是dump()而不是dumps()。

json.dump()

Serialize obj as a JSON formatted stream to fp (a .write()-supporting file-like object

If ensure_ascii is False, some chunks written to fp may be unicode instances

json.dumps()

Serialize obj to a JSON formatted str

If ensure_ascii is False, the result may contain non-ASCII characters and the return value may be a unicode instance
