使用Python apiclien从googlegwtappengine对Freebase进行多个MQL查询

Question

如何使用googleapi Python客户机库（http://wiki.freebase.com/wiki/Google_API_Client_Libraries#Python）重现以下MQL查询

https://api.freebase.com/api/service/mqlread?queries={"q1":[{"name~=":"*doubt*","name": None,"type": "/media_common/quotation","author": [{"name": "William Shakespeare"}]}], "q2":[{"name~=":"*law*","name": None,"type": "/media_common/quotation","author": [{"name": "William Shakespeare"}]}]}

以下单个查询有效：

^{pr2}$

我不知道如何将参数“query”更改为“querys”

在Google API Python Client的下一个版本（版本1.0 beta 9）中，您将能够像这样将多个查询批处理在一起：

from apiclient import discovery, model
from apiclient.http import BatchHttpRequest
import json

DEVELOPER_KEY = open('DEVELOPER_KEY').read()
query1 = [{"name~=":"*doubt*","name":None,"type":"/media_common/quotation","author":[{"name":"William Shakespeare"}]}]
query2 = [{"name~=":"*law*","name":None,"type":"/media_common/quotation","author":[{"name":"William Shakespeare"}]}]

model.JsonModel.alt_param = ""
freebase = discovery.build('freebase', 'v1', developerKey=DEVELOPER_KEY)

def display_results(request_id, response):
    for topic in response['result']:
        print topic['name']

batch = BatchHttpRequest(callback=display_results)
batch.add(freebase.mqlread(query=json.dumps(query1)))
batch.add(freebase.mqlread(query=json.dumps(query2)))
batch.execute(http)

使用这种技术，您可以组合多个查询，甚至MQL查询和搜索查询，它将只创建一个HTTP请求。在
