我检查了 https://jsonlint.com/ 上 json 文件的有效性，看起来没问题。现在，我正在尝试将 json 文件加载到 Python:
中的 TinyDB 数据库中
from tinydb import TinyDB, Query
db = TinyDB("tag.tg")
Line = Query()
result = db.search(Line.name == "ADC_CCR_DELAY_2")
print(result)
代码在第二行失败 db = TinyDB("tag.tg")。我收到以下错误：
TypeError: list indices must be integers or slices, not str
我做错了什么？我完全按照 tinydb 文档 https://pypi.python.org/pypi/tinydb:
>>> from tinydb import TinyDB, Query
>>> db = TinyDB('/path/to/db.json')
注：
我正在使用 Python 3.6.1
TinyDB 需要索引的 table 文档，而不是列表。除非您想为您的 TinyDB 编写自定义中间件，否则您要么必须将 JSON 修改为：

}
或者为您的现有数据编写自定义 'importer'：
import json
import tinydb
db = tinydb.TinyDB("db_storage.json") # create a new storage for the database
with open("tag.tg", "r") as f: # open the unmodified `tag.tg`
json_data = json.load(f) # parse its JSON
for entry in json_data: # iterate over each entry in the `tag.tg`
db.insert(entry) # insert it in the DB
更新：一些额外的信息，虽然有点超出了这个问题的范围。
正如我在评论中建议的那样，如果您打算使用大量 records/data，使用更优化的数据库可能是更好的主意。如果您需要使用 Python 本身交付的自封装端，SQLite 是一个不错的选择，但请记住它是一个 SQL 数据库而不是文档存储，因此您需要构建您的首先是架构，因此基于您的数据：
import sqlite3
connection = sqlite3.connect("db_store.sqlite") # 'connect' to the db_store.sqlite
cursor = connection.cursor() # get a cursor
cursor.execute("""
CREATE TABLE IF NOT EXISTS main
(_type TEXT, name TEXT, path TEXT, pattern TEXT,
typeref TEXT, kind TEXT, scope TEXT, scopeKind TEXT)
""") # create `main` table if it doesn't exist
然后你可以使用与 TinyDB 类似的方法来插入你的 tag.tg JSON - 加载它，解析它，插入它的项目：
import json
# load and parse the `tag.tg`
with open("tag.tg", "r") as f: # open the unmodified `tag.tg`
json_data = json.load(f) # parse its JSON
# fields that we're interested in, you can omit some if you don't want them in the DB
fields = ("_type", "name", "path", "pattern", "typeref", "kind", "scope", "scopeKind")
# prepare the insert query
query = "INSERT INTO main ({}) VALUES ({})".format(",".join(fields),
",".join(("?",) * len(fields)))
# now let's add the records to the SQLite table:
cursor = connection.cursor() # get a cursor
cursor.executemany(query, ([e.get(field, None) for field in fields] for e in json_data))
现在您可以执行以下操作：
cursor = connection.cursor() # get a cursor
cursor.execute("SELECT path FROM main WHERE name = 'ABFSR'") # a generic SQL SELECT
path, = cursor.fetchone() # get the first result
print("Path: " + path) # Path: Drivers\CMSIS\Include\core_cm7.h
它肯定能够处理比 TinyDB 多得多的记录，唯一的问题可能是导入您的初始 JSON 数据 - 如果您的系统无法处理整个 [=38] 的加载和解析=] 结构你可能想要寻找流式 JSON 解析器，尽管如果你所有的数据都是按照你所显示的结构（每行一个不同的 JSON 对象）可能需要一个通过删除周围的 [ 和 ] 以及逗号分隔符并逐行读取和解析文件来解决它。
我有以下 json- 文件：

或者为您的现有数据编写自定义 'importer'：
import json
import tinydb
db = tinydb.TinyDB("db_storage.json") # create a new storage for the database
with open("tag.tg", "r") as f: # open the unmodified `tag.tg`
json_data = json.load(f) # parse its JSON
for entry in json_data: # iterate over each entry in the `tag.tg`
db.insert(entry) # insert it in the DB
更新：一些额外的信息，虽然有点超出了这个问题的范围。
正如我在评论中建议的那样，如果您打算使用大量 records/data，使用更优化的数据库可能是更好的主意。如果您需要使用 Python 本身交付的自封装端，SQLite 是一个不错的选择，但请记住它是一个 SQL 数据库而不是文档存储，因此您需要构建您的首先是架构，因此基于您的数据：
import sqlite3
connection = sqlite3.connect("db_store.sqlite") # 'connect' to the db_store.sqlite
cursor = connection.cursor() # get a cursor
cursor.execute("""
CREATE TABLE IF NOT EXISTS main
(_type TEXT, name TEXT, path TEXT, pattern TEXT,
typeref TEXT, kind TEXT, scope TEXT, scopeKind TEXT)
""") # create `main` table if it doesn't exist
然后你可以使用与 TinyDB 类似的方法来插入你的 tag.tg JSON - 加载它，解析它，插入它的项目：
import json
# load and parse the `tag.tg`
with open("tag.tg", "r") as f: # open the unmodified `tag.tg`
json_data = json.load(f) # parse its JSON
# fields that we're interested in, you can omit some if you don't want them in the DB
fields = ("_type", "name", "path", "pattern", "typeref", "kind", "scope", "scopeKind")
# prepare the insert query
query = "INSERT INTO main ({}) VALUES ({})".format(",".join(fields),
",".join(("?",) * len(fields)))
# now let's add the records to the SQLite table:
cursor = connection.cursor() # get a cursor
cursor.executemany(query, ([e.get(field, None) for field in fields] for e in json_data))
现在您可以执行以下操作：
cursor = connection.cursor() # get a cursor
cursor.execute("SELECT path FROM main WHERE name = 'ABFSR'") # a generic SQL SELECT
path, = cursor.fetchone() # get the first result
print("Path: " + path) # Path: Drivers\CMSIS\Include\core_cm7.h
它肯定能够处理比 TinyDB 多得多的记录，唯一的问题可能是导入您的初始 JSON 数据 - 如果您的系统无法处理整个 [=38] 的加载和解析=] 结构你可能想要寻找流式 JSON 解析器，尽管如果你所有的数据都是按照你所显示的结构（每行一个不同的 JSON 对象）可能需要一个通过删除周围的 [ 和 ] 以及逗号分隔符并逐行读取和解析文件来解决它。
