将JSON文本作为命令行参数传递

本文介绍了将JSON文本作为命令行参数传递的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试将以下JSON文本传递到我的python代码中.

I am trying to pass the following JSON text into my python code.

{"platform": "android", "version": "6.0.1"}

我的代码如下.

import sys import json data = json.loads(sys.argv[1]) print(str(data))

在Windows 10 PowerShell上运行以下命令时，

When running the following on Windows 10 PowerShell,

python jsonTest.py '{"platform": "android", "version": "6.0.1"}'

我得到以下信息:

Traceback (most recent call last): File "jsonTest.py", line 3, in <module> data = json.loads(sys.argv[1]) File "C:\Users\Rishabh Bhatnagar\AppData\Local\Programs\Python\Python36- 32\lib\json\__init__.py", line 354, in loads return _default_decoder.decode(s) File "C:\Users\Rishabh Bhatnagar\AppData\Local\Programs\Python\Python36- 32\lib\json\decoder.py", line 339, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "C:\Users\Rishabh Bhatnagar\AppData\Local\Programs\Python\Python36- 32\lib\json\decoder.py", line 355, in raw_decode obj, end = self.scan_once(s, idx) json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

据我所知，我接受了我的代码，并正确地传递了JSON文本.我不知道我在做什么错.我知道JSON文本有效(已通过 jsonlint/进行了检查).谢谢.

As far as I know, I take my code, and pass the JSON text properly. I can't figure out what I'm doing wrong. I know the JSON text is valid (checked with jsonlint/). Thanks.

推荐答案

所以我知道了.

sys.argv[1]

上一行是将我的Json文本带到下面，并从中删除引号.

The above line was taking my Json text below and taking out the quotes from it.

{"platform": "android", "version": "6.0.1"}

进入

{platform: android, version: 6.0.1}

我的解决方法是按如下方式运行它.

My workaround is to run it as follows.

Python jsonTest.py '{\"platform\": \"android\", \"version\": \"6.0.1\"}'

我将尝试找到一种更好的方法，但是到今天为止，我已经完成了.

I will try to find a better way, but for today, I'm done.
