使用python从命令行传递的json参数无法解码 [英] json argument passed from the command line with python can't be decoded

问题描述

我正在尝试将命令行参数传递给python文件并加载json，但是我不断收到值错误:无法解码Json对象.

I am trying to pass a command line argument to a python file and load the json but I keep getting a valueerror: No Json object could be decoded.

json_test.py:

json_test.py:

import json
import sys

json_dict = json.loads(sys.argv[1])

然后我使用以下命令在命令行中运行它:

I then run this in the command line using:

python json_test.py '{"favorited": false, "contributors": null}'

即使我在网上找到了这作为正确JSON的示例，也遇到了一个错误.有什么想法吗?

And I get an error, even though I found this as an example of correct JSON on the web. Any ideas?

推荐答案

如果运行 print sys.argv [1] ，则可能会得到'{favorited:json模块无法解码为json对象.

if you run print sys.argv[1] you probably get '{favorited: which the json module cannot decode into a json object.

尝试转义内部引号，以便将其作为1个参数传递，如下所示:

try escaping your inner quotes so it is passed as 1 argument like so:

"{"\""favorited"\"": false, "\""contributors"\"": null}"
