Python的主要错误缺少快译通在LinkedIn的API调用 - 如何调用默认值呢？ [英] Python Key Error Missing Dict in LinkedIn API call - how to call default value instead?
问题描述
我打电话LinkedIn的API和使用json.loads到JSON对象转换为Python列表和类型的字典。有时候，某些LinkedIn个人资料，他们缺少的字典，如结束日期为他们的大学/教育（下面以粗体显示）。我会用什么机制来使其返回默认值（即N / A），而不是绊倒了失踪的字典键错误呢？我这样一个基本问题道歉，我刚开始使用Python / Django的。我真的AP preciate的帮助！
高清家庭（要求）：
现在= datetime.datetime.now（）
HTML =＆LT; HTML和GT;＆LT;身体GT;
令牌= oauth.Token（request.user.get_profile（）组oauth_token，request.user.get_profile（）。oauth_secret）
客户端= oauth.Client（消费者，令牌）
标题= {'X丽格式'：'JSON'}
URL_LIST = [绝密-URL，绝密-URL，绝密-URL]
在URL_LIST X：
URL = \"http://api.linkedin.com/v1/people/url=\"+x+\":(id,first-name,last-name,headline,industry,three-current-positions,**educations:(end-date,**degree,field-of-study,school-name))\"
RESP，内容= client.request（URL，GET，标题=标题）
简介= json.loads（内容）
HTML + =轮廓['的firstName'] ++简介['lastName的'] +：+简介['标题'] +|+简介['产业'] +|+简介['threeCurrentPositions '] ['值'] [0] ['公司'] ['名'] +|+简介['threeCurrentPositions'] ['值'] [0] ['标题'] +|+简介['的教育'] ['值'] [0] ['fieldOfStudy'] +|+简介['的教育'] ['值'] [0] ['度'] +|+简介['的教育'] ['值'] [0] ['schoolName'] +|** + STR（简介['的教育'] ['值'] [0] ['结束日期'] ['年']） ** +＆下; p /＆gt;中
返回的Htt presponse（HTML）
您可以使用 dict.get（键，默认）而不是字典[关键] 做一个字典查找时指定一个默认值。
I am calling the linkedin API and using json.loads to convert the JSON objects to Python lists and dicts. Sometimes for certain LinkedIn profiles, they are missing a dict such as the end date for their university/education (bolded below). What mechanism would I use to have it return a default value (i.e "N/A") instead of tripping up a "Key Error" for missing the dict? I apologize for such a basic question, I'm just starting out with Python / Django. I really appreciate the help!
def home(request):
now = datetime.datetime.now()
html = "<html><body>"
token = oauth.Token(request.user.get_profile().oauth_token,request.user.get_profile().oauth_secret)
client = oauth.Client(consumer,token)
headers = {'x-li-format':'json'}
url_list = ["redacted-URL","redacted-URL", "redacted-URL"]
for x in url_list:
url = "http://api.linkedin.com/v1/people/url="+x+":(id,first-name,last-name,headline,industry,three-current-positions,**educations:(end-date,**degree,field-of-study,school-name))"
resp, content = client.request(url, "GET", headers=headers)
profile = json.loads(content)
html += profile['firstName'] + " " + profile['lastName'] + ": " + profile['headline'] + " | " + profile['industry'] + " | " + profile['threeCurrentPositions']['values'][0]['company']['name']+ " | " + profile['threeCurrentPositions']['values'][0]['title']+ " | " + profile['educations']['values'][0]['fieldOfStudy']+ " | " + profile['educations']['values'][0]['degree']+ " | " + profile['educations']['values'][0]['schoolName']+ " | " **+str(profile['educations']['values'][0]['endDate']['year'])** + "<p/>"
return HttpResponse(html)
You can use dict.get(key, default) instead of dict[key] to specify a default value when doing a dictionary lookup.
