Python：如何在list / json中保留单引号

Question

I am creating a rest api in Python using flask and using curl command to test my function.

Curl Command:

$ curl -X POST 
  -H "Content-Type:application/json"
  -d '{"keyword": "2''binders", "country": "xyz", "frequency": "1","url":"www.example.com"}' \
  http://127.0.0.1:5000/google

Output:

'['New Request', u'**2binders**', u'xyz', u'www.example.com', u'1']'

As you can see I am passing inches in json 2''binders but in my list it is removing that.

Edit:

Python: json = request.get_json(force=True) print json

Answer 1

In your curl command, try using "keyword": "2\\'\\'binders" . You need to escape the single quotes inside the -d parameter, because you're using single quotes around the -d parameter.

The shell is getting confused and thinking you are wanting string concatenation. Eg the shell is seeing 'abc''def' and interpreting that as 'abcdef' .

Answer 2

If you try to json.dumps the dictionary itself:

>>> s = json.dumps(d)
>>> 
>>> s
'{"url": "www.example.com", "country": "xyz", "frequency": "1", "keyword": "2\'\'binders"}'
                                                                              ^ ^

You will see that it will automatically escape ' , as mentioned in the previous answer, escaping it should do the trick to you:

>>> json.loads(s)
{u'url': u'www.example.com', u'country': u'xyz', u'frequency': u'1', u'keyword': u"2''binders"} #Single quote is back

Answer 3

Got it!!!

curl -X POST -d '{"keyword": "2'\\'''\\''binders", "country": "xyz", "frequency": "1","url":" http://www.example.com/ "}' http://127.0.0.1:5000/google -H "Content-Type:application/json"
