URL：https://www.ted.com/talks/emily_balcetis_why_some_people_find_exercise_harder_than_others/transcript.json?language=en

import json
import requests
url = "https://www.ted.com/talks/emily_balcetis_why_some_people_find_exercise_harder_than_others/transcript.json?language=en"
data = requests.get(url).json()

实际上，我正在解析100多个URL，但是有时会遇到错误，而有时却没有。例如，此URL 1小时前并未引发此错误，而现在正在引发。

Traceback (most recent call last): File "tedcrawler.py", line 89, in <module> EnglishTranscript(url) File "tedcrawler.py", line 58, in EnglishTranscript data = requests.get(url).json() File "/usr/local/lib/python2.7/dist-packages/requests/models.py", line 896, in json return complexjson.loads(self.text, **kwargs) File "/usr/lib/python2.7/dist-packages/simplejson/__init__.py", line 516, in loads return _default_decoder.decode(s) File "/usr/lib/python2.7/dist-packages/simplejson/decoder.py", line 370, in decode obj, end = self.raw_decode(s) File "/usr/lib/python2.7/dist-packages/simplejson/decoder.py", line 400, in raw_decode return self.scan_once(s, idx=_w(s, idx).end()) simplejson.scanner.JSONDecodeError: Expecting value: line 2 column 1 (char 1)

已解决：错误是由于请求数过多（状态码为429

）

Answer 1

可能您收到速率限制或其他一些服务器端错误。您可以尝试检查状态代码是否为status_ok，然后解析json。

import json
import requests

url = "https://www.ted.com/talks/emily_balcetis_why_some_people_find_exercise_harder_than_others/transcript.json?language=hi"

data = requests.get(url)
print data.status_code
if data.status_code == 200:
     print data.json()

获取simplejson.scanner.JSONDecodeError：预期值：第2行第1列（字符1）
