[英]Parse the following query string into json using python
I have a query string with the following format: 我有以下格式的查询字符串:
cmd=get-records&limit=100&offset=0&search[0][field]=number&search[0][type]=text&search[0][operator]=contains&search[0][value]=Mike+Jones&search[1][field]=name&search[1][type]=text&search[1][operator]=contains&search[1][value]=Mike+Jones&search[2][field]=role&search[2][type]=text&search[6]&searchLogic=OR
How can I convert this to structured json like the following (or similar): 如何将其转换为结构化json,如下所示(或类似内容):
{
cmd: "...",
limit: "...",
offset: "...",
search: {
0: {
number: "..."
name: "...",
...
}
1: {
...
}
...
},
...
}
I have tried to use urlparse.parse_qs
but it translates the query string to the following: 我尝试使用
urlparse.parse_qs
但是它将查询字符串转换为以下内容:
{
"cmd": ["..."],
"limit": ["..."],
"offset": ["..."],
"search[0][number]": ["..."],
"search[0][name]": ["..."],
"search[1][number]": ["..."].
...
}
The problem with this is the search fields. 问题在于搜索字段。 I want this to be correctly structured.
我希望这个结构正确。 The technologies I am using are as following:
我使用的技术如下:
Frontend: 前端:
w2ui table that requests data from the backend. w2ui表从后端请求数据。 Also, as shown in this example, when doing a search it sends a request to the backend to do the search.
同样,如本例所示,在进行搜索时,它会向后端发送一个请求以进行搜索。
Backend: 后端:
Django. Django的。 The post request from w2ui is handled by a view which takes in the query string and acts accordingly.
来自w2ui的发布请求由一个视图处理,该视图接受查询字符串并采取相应的行动。
Take a look at the querystring-parser package, which does exactly what you need: 看一看querystring-parser软件包,它确实满足您的需求:
import pprint
from querystring_parser import parser as qsparser
# I had to modify the query string you provided by adding a value
# search[6]; it didn't have one before, which caused an exception
query_string = (
'cmd=get-records&limit=100&offset=0&search[0][field]=number&'
'search[0][type]=text&search[0][operator]=contains&'
'search[0][value]=Mike+Jones&search[1][field]=name&search[1][type]=text&'
'search[1][operator]=contains&search[1][value]=Mike+Jones&'
'search[2][field]=role&search[2][type]=text&search[6]=SEARCH6&'
'searchLogic=OR'
) # NOTE: I had
query_string_as_dict = qsparser.parse(query_string)
pprint.pprint(query_string_as_dict)
The result is: 结果是:
{u'cmd': u'get-records',
u'limit': 100,
u'offset': 0,
u'search': {0: {u'field': u'number',
u'operator': u'contains',
u'type': u'text',
u'value': u'Mike Jones'},
1: {u'field': u'name',
u'operator': u'contains',
u'type': u'text',
u'value': u'Mike Jones'},
2: {u'field': u'role', u'type': u'text'},
6: u'SEARCH6'},
u'searchLogic': u'OR'}
If you want it as JSON: 如果您希望将其作为JSON:
import json
json_string = json.dumps(query_string_as_dict)
Perhaps take a look at this library: querystring-parser 也许看看这个库: querystring-parser
It takes section[1]['words'][2]=a§ion[0]['words'][2]=a§ion[0]['words'][2]=b
and converts it to {u'section': {0: {u'words': {2: [u'a', u'b']}}, 1: {u'words': {2: u'a'}}}}
which looks like what you're after. 它需要
section[1]['words'][2]=a§ion[0]['words'][2]=a§ion[0]['words'][2]=b
并将其转换为{u'section': {0: {u'words': {2: [u'a', u'b']}}, 1: {u'words': {2: u'a'}}}}
,看起来像你在追求什么。
Their docs for using it within Django: 他们在Django中使用它的文档:
from querystring_parser import parser
post_dict = parser.parse(request.GET.urlencode())
如果您使用的是Django,则可以在视图内部按request.GET
组织此类信息。
