我有a.json个文件，内容如下：

{"created_at": "Fri Feb 01 03:19:49 +0000 2019", "id": 1091174254324928512, "id_str": "1091174254324928512", "text": "\u091c\u094b \u091c\u0940\u0902\u0926 \u0915\u093e \u092e\u0942\u0921 \u0939\u0948, \u0935\u0939\u0940 \u0939\u093f\u0928\u094d\u0926 \u0915\u093e \u092e\u0942\u0921 \u0939\u0948 \u270c\ufe0f\n\n#JindByPollResults #JindByelection\n#jindbypoll #JindResults\n#fridayfeelings", "truncated": false, "entities": {"hashtags": [{"text": "JindByPollResults", "indices": [43, 61]}, {"text": "JindByelection", "indices": [62, 77]}, {"text": "jindbypoll", "indices": [78, 89]}, {"text": "JindResults", "indices": [90, 102]}, {"text": "fridayfeelings", "indices": [103, 118]}], "symbols": [], "user_mentions": [], "urls": []}, "source": "<a href=\"http://twitter.com/download/android\" rel=\"nofollow\">Twitter for Android</a>", "in_reply_to_status_id": null, "in_reply_to_status_id_str": null, "in_reply_to_user_id": null, "in_reply_to_user_id_str": null, "in_reply_to_screen_name": null, "user": {"id": 439154852, "id_str": "439154852", "name": "Chowkidar Kailash Vijayvargiya", "screen_name": "KailashOnline", "location": "Delhi", "description": "National General Secretary of #BJP, Active Worker & a Proud Indian who continuously strives for development.", "url": "https://twitter.com/KbWcYpNlEZ", "entities": {"url": {"urls": [{"url": "https://twitter.com/KbWcYpNlEZ", "expanded_url": "http://www.KailashOnline.in", "display_url": "KailashOnline.in", "indices": [0, 23]}]}, "description": {"urls": []}}, "protected": false, "followers_count": 756260, "friends_count": 1777, "listed_count": 243, "created_at": "Sat Dec 17 12:36:56 +0000 2011", "favourites_count": 7206, "utc_offset": null, "time_zone": null, "geo_enabled": true, "verified": true, "statuses_count": 17644, "lang": "en", "contributors_enabled": false, "is_translator": false, "is_translation_enabled": false, "profile_background_color": "000000", "profile_background_image_url": "http://abs.twimg.com/images/themes/theme1/bg.png", "profile_background_image_url_https": "https://abs.twimg.com/images/themes/theme1/bg.png", "profile_background_tile": true, "profile_image_url": "http://pbs.twimg.com/profile_images/1073134305466114048/Kx-Y7xkk_normal.jpg", "profile_image_url_https": "https://pbs.twimg.com/profile_images/1073134305466114048/Kx-Y7xkk_normal.jpg", "profile_banner_url": "https://pbs.twimg.com/profile_banners/439154852/1544690191", "profile_link_color": "E06412", "profile_sidebar_border_color": "000000", "profile_sidebar_fill_color": "DDEEF6", "profile_text_color": "333333", "profile_use_background_image": true, "has_extended_profile": true, "default_profile": false, "default_profile_image": false, "following": false, "follow_request_sent": false, "notifications": false, "translator_type": "none"}, "geo": null, "coordinates": null, "place": null, "contributors": null, "is_quote_status": false, "retweet_count": 663, "favorite_count": 2705, "favorited": false, "retweeted": false, "lang": "hi"}

如您所见，id字段值为= 1091174254324928512

在python3中，带有原始a.json 

>>> import json
>>> f=open("a.json","r")
>>> d=json.load(f)
>>> d["id"]
1091174254324928512

当我使用命令打印相同的文件时 cat a.json | jq .
我得到以下输出

}

此处打印的id字段值= 1091174254324928500，与文件中存在的id字段值不同。

在python3中，以美化的pretty_a.json 

>>> import json
>>> f=open("pretty_a.json","r")
>>> d=json.load(f)
>>> d["id"]
1091174254324928500

此外，当我使用VSCode打开a.json并使用prettify_JSON扩展名时，我得到的美化输出与使用cat a.json | jq .打印的输出相同。

所以我认为问题是因为json解码器如何处理数字数据类型。
似乎jq和python3的json解码器对数据类型的处理方式不同。

我的问题是，到底发生这种情况的原因是什么，以及如何在使用json的{​​{1}}模块进行编码的同时处理这些类型的特殊性，而不管给定的json文件是否经过python3修饰。
