將json文件讀入python-錯誤：期望值：第1行第1列（字符0）

[英]Reading json file into python - Error: Expecting value: line 1 column 1 (char 0)

 原文  2019-08-28 10:43:57  2   2    python/ json/ python-3.x/ twitter

問題描述

我從Twitter API獲得了一個包含500條推文的json文件。 它們存儲為.json，我需要將它們加載到python中。

我嘗試了多種加載/讀取文件的方式，但是沒有任何效果。 文件可能有問題嗎？

我得到的錯誤是：

期望值：第1行第1列（字符0）

這是我嘗試過的許多方法之一： 

file = 'resources/data/raw/500_random_tweets.json'

try:
    with open(file, 'r', encoding="utf8") as myfile:
        data = myfile.read()

    tweets = json.loads(data)

except Exception as e:
    print(e)

這是json的樣子：

JSON不支持注釋。 在這里閱讀有關它的更多信息： 注釋可以在JSON中使用嗎？

就您而言，您應該只刪除文件開頭的/* 1 */ 。 那可行。

我注意到您的文件中有多個json對象。 每個對象都標記有這些注釋之一。 您應該在這些位置拆分文件，以確保將所有不同的json對象也加載到不同的python對象中。

這是一個正則表達式示例，用於將文件拆分為不同的json對象： 

import re
re.split("/\* [0-9]+ \*/\n", data)

此正則表達式在文件中具有注釋的格式。

編輯 ：我注意到您的文件實際上並不包含真實的json數據。 可能是bson。 您可以使用工具“ bsondump”將其轉換為真實的json： https ：//docs.mongodb.com/manual/reference/program/bsondump/

閱讀Daniel Roseman的答案以獲取有關bson的更多詳細信息。

該文件不是JSON。 它不僅以注釋開頭，還包含幾種類型-ObjectId，NumberLong，ISODate-JSON也不支持。

相反，它似乎是BSON ，這是MongoDb使用的序列化格式。 您需要從MongoDb庫安裝BSON客戶端才能讀取它。
