Json-rpc 2.0 -如何提取数据

Question

我正在尝试从一个内部项目(http：\192.168.1.15:8082)中提取数据。它使用json-rpc 2.0。一开始，我试着用美容汤检索信息，因为它是在屏幕上显示的，但这不起作用，我得到的只是一堆函数代码。我不熟悉json-rpc。欢迎任何帮助。

网站上打印的回复数据如下所示：

响应：

{"jsonrpc":"2.0","result":[{"uri":"Geometry","time":1537525006,"geo":{"type":"characteristic","id":125,"information2":{"type":"Point","Weight":[15.362154,196.623546]}

如何检索此信息？

谢谢大家

尼克

看看requests https://pypi.org/project/requests

要遵守该标准，您需要将payload放入您的请求，否则它只是一个普通的post

import requests
import json

def main():
    url = "http://192.168.1.15:8082/jsonrpc"
    headers = {'content-type': 'application/json'}

    # Example echo method
    payload = {
        "method": "your_method_name",
        "jsonrpc": "2.0",
        "id": 0,
    }
    response = requests.post(
        url, data=json.dumps(payload), headers=headers).json()

    print(response)
    print(response['result']['uri'])
    print(response['result']['time'])
    print(response['result']['geo'])
    print(response['result']['geo']['id'])
    print(response['result']['geo']['type'])
    print(response['result']['geo']['information2'])
    print(response['result']['geo']['information2']['type'])
    print(response['result']['geo']['information2']['Weight'])

if __name__ == "__main__":
    main()

如果您想要特定于json_rpc的东西，那么可以看看jsonrpc_requests https://pypi.org/project/jsonrpc-requests/

请注意，在这个示例中，响应的反序列化是如何为您处理的，并且您只会返回方法调用的结果，而不是整个响应。

from jsonrpc_requests import Server

def main():
    url = "http://localhost:8082/jsonrpc"
    server = Server(url)
    result  = server.dosomething()


    print(result)
    print(result['uri'])
    print(result['time'])
    print(result['geo'])
    print(result['geo']['id'])
    print(result['geo']['type'])
    print(result['geo']['information2'])
    print(result['geo']['information2']['type'])
    print(result['geo']['information2']['Weight'])

if __name__ == "__main__":
    main()
