如何从web.py服务器应用程序中的Post获取JSON值？ [英] How to obtain JSON value from Post in a web.py server app?

问题描述

我正在使用Python 2.7.6和web.py服务器来尝试一些简单的Rest调用...

Am using Python 2.7.6 along with web.py server to experiment with some simple Rest calls...

希望将JSON有效负载发送到我的服务器，然后打印有效载荷的值...

Wish to send a JSON payload to my server and then print the value of the payload...

示例有效载荷

{"name":"Joe"}

这是我的python脚本

Here's my python script

#!/usr/bin/env python
import web
import json

urls = (
    '/hello/', 'index'
)

class index:
    def POST(self):
        # How to obtain the name key and then print the value?
        print "Hello " + value + "!"

if __name__ == '__main__':
    app = web.application(urls, globals())
    app.run()

这是我的cURL命令：

Here's my cURL command:

curl -H "Content-Type: application/json" -X POST -d '{"name":"Joe"}' http://localhost:8080/hello

我期望对此做出响应（纯文本）：

Am expecting this for the response (plain text):

Hello Joe!

推荐答案

您必须解析json：

#!/usr/bin/env python
import web
import json

urls = (
    '/hello/', 'index'
)

class index:
    def POST(self):
        # How to obtain the name key and then print the value?
        data = json.loads(web.data())
        value = data["name"]
        return "Hello " + value + "!"

if __name__ == '__main__':
    app = web.application(urls, globals())
    app.run()

另外，请确保您的网址是 http：// localhost：8080 / hello / 在您的 cURL 请求中；您的示例中有 http：// localhost：8080 / hello ，这会引发错误。

Also, make sure you're url is http://localhost:8080/hello/ in your cURL request; you have http://localhost:8080/hello in your example, which throws an error.
