Python HTTP API的嵌套GET参数

我试图使用python请求来使用某个API

我试过：

import requests
data = ?
r = requests.get('http://localhost:8777/v2/meters/instance', params=data)

我想构建的查询如下：

http://localhost:8777/v2/meters/instance?q.field=project_id&q.value=s56464dsf6343466

我的问题是，我如何才能通过q.field=project\u id&q.value=s56464dsfs6343466

我试过这样做，但不起作用

data = { 'q': [{'field':'project_id', 'value': 's56464dsf6343466'}] }

我希望有人能帮忙。

您必须明确地命名每个参数：

data = {'q.field':'project_id', 'q.value': 's56464dsf6343466'}

没有将更复杂的结构编组为GET查询参数的标准；现有的唯一标准为您提供键值对。因此，请求库不支持任何其他内容

当然，您可以编写自己的封送拆收器，该封送拆收器接受嵌套的字典或列表，并为您生成一个简单的字典或键值对元组。

您必须首先对数据进行编码，如下所示：

from requests import get
from urllib import urlencode

url = 'http://localhost:8777/v2/meters/instance'
data = {'q': [{'field':'project_id', 'value': 's56464dsf6343466'}]}
get(url, params=urlencode(data), headers=HDR)

from ast import literal_eval

@route('/v2/meters/instance')
def meters():
    kwargs = request.args.to_dict()
    # kwargs is {'q': "[{'field':'project_id', 'value': 's56464dsf6343466'}]"}
    kwargs = {k: literal_eval(v) for k, v in kwargs.iteritems()}
    # kwargs is now {'q': [{'field':'project_id', 'value': 's56464dsf6343466'}]}

然后你像这样解码它：

from requests import get
from urllib import urlencode

url = 'http://localhost:8777/v2/meters/instance'
data = {'q': [{'field':'project_id', 'value': 's56464dsf6343466'}]}
get(url, params=urlencode(data), headers=HDR)

from ast import literal_eval

@route('/v2/meters/instance')
def meters():
    kwargs = request.args.to_dict()
    # kwargs is {'q': "[{'field':'project_id', 'value': 's56464dsf6343466'}]"}
    kwargs = {k: literal_eval(v) for k, v in kwargs.iteritems()}
    # kwargs is now {'q': [{'field':'project_id', 'value': 's56464dsf6343466'}]}
