Question

我使用的是pyhton3.4.1。

我正在使用谷歌自定义搜索。

我想获得链接，但它是diplay TypeError：字符串索引必须是整数。

以下是我的代码和JSON格式。

from urllib.request import urlopen
import json
u = urlopen('https://www.googleapis.com/customsearch/v1?key=AIzaSyC3jpmwO3Ieifw1VnrVoL3mS3KSE_GMRvo&cx=010407088344546736418:onjj7gscy2g&q=lol&num=10')
resp = json.loads(u.read().decode('utf-8'))
for link in resp:
  for k in link['item']:
    print(k['link'])

和JSON fomat如下所示。

 "items": [
{
"kind": "customsearch#result",
"title": "League of Legends",
"htmlTitle": "<b>League of Legends</b>",
"link": "http://leagueoflegends.com/",
"displayLink": "leagueoflegends.com",
