RIOTAPI的JSON格式错误

编程问答 2022-08-14

问题描述

我正在从API将JSON数据导入Python，并遇到以下解码错误：

JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

看看在线示例，它会立即清除我的JSON数据具有'，其他人具有"。

理想情况下，我想知道为什么以这种方式下载它。看来这很可能是我的错误，而不是他们的错误。

我认为改正JSON格式应该很容易，但是我在这里也失败了。请参阅下面的代码，了解如何获取JSON数据以及如何修复它。

#Must first have installed riotwatcher

#Info in my example is made up,I can't supply a real API code or
#I get in trouble. Sorry about this. You could obtain one from their website
#but this would be a lot of faff for what is probably a simple StackOverflow
#question

#If you were to get/have a key you could use the following information:
#<EUW> for region
#<Agurin> for name

#----------------------------------------
#---Code
#----------------------------------------


#--->Set Variables


#Get installed riotwatcher module for
#Python
import riotwatcher

#Import riotwatcher tools.
from riotwatcher import LolWatcher,ApiError

#Import JSON (to read the JSON API file)
import json

# Global variables
# Get new API from
# https://developer.riotgames.com/
api_key = 'RGAPI-XXXXXXX-XXX-XXXX-XXXX-XXXX'
watcher = LolWatcher(api_key)
my_region = 'MiddleEarth'

#need to give path to where records
#are to be stored
records_dir = "/home/solebaysharp/Projects/Riot API/Records"


#--->Obtain initial data,setup new varaibles

#Use 'watcher' to get basic stats and setup my account as a variable (me)
me = watcher.summoner.by_name(my_region,"SolebaySharp")

# Setup retrieval of recent match info
my_matches = watcher.match.matchlist_by_account(my_region,me["accountId"])
print(my_matches)

#--->Download the recent match data

#Define where the JSON data is going to go
recent_matches_index_json = (records_dir + "/recent_matches_index.json")

#get that JSON data
print ("Downloading recent match history data")
file_handle = open(recent_matches_index_json,"w+")
file_handle.write(str(my_matches))
file_handle.close()

#convert it to python
file_handle = open(recent_matches_index_json,)
recent_matches_index = json.load(file_handle)

除了这个给予者以下错误... 

JSONDecodeError: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)

所以我改正了这个问题：

file_handle = open(recent_matches_index_json)

json_sanitised = json.loads(file_handle.replace("'",'"'))

这将返回... 

AttributeError: '_io.TextIOWrapper' object has no attribute 'replace'

为了完整起见，下面是JSON外观的示例。我添加了段落以增强可读性。不是这样的。

{'matches': [
  {'platformId': 'NA1','gameId': 5687555181,'champion': 235,'queue': 400,'season': 13,'timestamp': 1598243995076,'role': 'DUO_SUPPORT','lane': 'BOTTOM'
   },{'platformId': 'NA1','gameId': 4965733458,'timestamp': 1598240780841,'gameId': 4583215645,'champion': 111,'timestamp': 1598236666162,'lane': 'BOTTOM'
   }],'startIndex': 0,'endIndex': 100,'totalGames': 186}
