如何从Rest API获取数据并将JSON保存到txt文件？

Question

I am trying to get some data from a rest api and save a JSON to a txt-file. Here is what I do:

#random rest api
a = 'https://thiswouldbemyurl.com'

#urllib3 + poolmanager for requests
import urllib3
http = urllib3.PoolManager()

import json
r = http.request('GET', a)
json.loads(r.data.decode('utf-8'))

with open('data.txt', 'w') as f:
  json.dump(data, f, ensure_ascii=False)

I get an error already with json.load . What am I doing wrong?

EDIT: This is how the JSON looks like

{
   "success":true,
   "data":[
      {
         "id":26,
         "name":"A",
         "comment":"",
         "start_time_plan":null,
         "start_time_actual":"2016-09-13 00:00:00",
         "start_time_delta":null,
         "start_time_score":null,
         "start_time_score_achievement":null,
         "start_time_traffic_light":null,
         "end_time_plan":null,
         "end_time_actual":"2016-09-13 00:00:00",
         "end_time_delta":null,
         "end_time_score":null,
         "end_time_score_achievement":null,
         "end_time_traffic_light":null,
         "status":0,
         "measure_schedule_revision_id":63,
         "responsible_user_id":3,
         "created_time":"2016-09-13 11:29:14",
         "created_user_id":3,
         "modified_time":"2016-09-21 16:33:41",
         "modified_user_id":3,
         "model":"Activity"
      }

It sounds like you're trying to json.load(...) something that is not actually JSON.

Looking at the URL you're using, https://jsonplaceholder.typicode.com/ returns HTML rather than JSON.

If you use something like https://jsonplaceholder.typicode.com/posts which does return JSON, then that particular error should go away.
