我正在尝试从API调用响应。我不确定出了什么问题,也许响应不是有效的JSON,但我不确定。看起来json模块也没有初始化。我已经设法调用了没有json的数据。loads(data),但我需要将响应转换为dict,这样我就可以在格式化的字符串中使用它,例如print(“以下是{query}的三个建议的FAST术语:“,{auth1},{fast_id1},{auth2},{fast_id2},{auth3},{fast_id3})

# http://fast.oclc.org/searchfast/fastsuggest?&query=[query]&queryIndex=[queryIndex]&queryReturn=[queryReturn]&suggest=autosuggest&rows=[numRows]&callback=[callbackFunction]

import json
import requests

### CALLING API
data = requests.get('http://fast.oclc.org/searchfast/fastsuggest?&query=hog&queryIndex=suggestall&queryReturn=suggestall%2Cidroot%2Cauth%2Ctag%2Ctype%2Craw%2Cbreaker%2Cindicator&suggest=autoSubject&rows=3&callback=testcall').text

data_text = json.loads(data)

print(data_text)

错误:

响应中有前缀

data[:10]
'testcall({'

如果你把它切下来就行了

data_text = json.loads(data[9:-1])

然而,似乎该网站不工作的财产,因为它不提供正确的JSON

因为你的json不正确。你的变量数据是字符串类型,因此不能作为json加载
