The use of a watercress API--rejecting the mindset

Haven't written a blog for a long time, recently has been using the Watercress API crawl data, do not know what was the previous, after all, just start with not long, with the latest V2 version, the previous not updated, you can refer to https://developers.douban.com/wiki/?title= API_V2, but in the use of some APIs will be some problems, you need to ponder, because there is not much information on the API crawling data, today talk about some watercress with the city V2 an interface call-get the list of activities.

According to the interface provided by the Watercress V2, get the list of activities:GET https://api.douban.com/v2/event/list，返回值是eventlist，其格式可以自己查询，我们试一下：

Try :         = Urllib2.urlopen (R'https://api.douban.com/v2/event/list')                           except  Exception as ex:    print= json.loads (html.read ()) EventList (Hjson) 

This is the main code, EventList is defined as a function, output activity list, run, error, 400bad request, or do not know what reason, jump from the Web page https://api.douban.com/v2/event/list, Get a file, open with a browser, display information for

{"MSG": "Invalid_parameter", "code": 1016, "request": "GET \/v2\/event\/list"}

, the parameter is wrong, my God, what ghost, do not follow the API said, how wrong? Can't get the list to work? Try getting a list of cities:

Try :         = Urllib2.urlopen (R'https://api.douban.com/v2/loc/list')                except  Exception as ex:    print= json.loads (html.read ()) City_print (Hjson) 

City_print for the definition of the output city list of functions, run, perfect output, brother, blindfolded. What is the reason, Baidu, no progress, or Google a bit (hehe), but also rely on their own. Looking for ideas from the source, open the watercress, into the same city sub-module, found that the upper left corner of your location, the brain flashed a thought: will it be acquired when the name of the designated place? Try it now, but how to designate a place name, think of a few days before climbing watercress film top250 when there is a start parameter, this is not also useful, which words to use. In the see Get the city list of the interface, is loc/list, that designated place name also use this try, say dry do:

Try :         = Urllib2.urlopen (R'https://api.douban.com/v2/event/list?loc=qingdao')                                                       except Exception as ex:     Print  = json.loads (html.read ()) EventList (Hjson)

Because I am in Qingdao, I designate the place name as Qingdao, run for a while, look at some data briefly:
