在python中将Bson转换为Json

我的情况是，我只能以字节的形式读取BSON文件（它是Apache Beam字节编码器）。因此，我将BSON文件内容作为字节。现在我尝试将其转换为JSON。我的代码是：

from bson import json_util
import apache_beam as beam

class ParseBsontoJson(beam.DoFn):
    def process(self, element):
        print(type(element))
        # data = bson.BSON.decode(bson.BSON(element))
        data = element.decode('utf-8')
        # data = bson.decode_all(element)
        # data2 = json_util.dumps(data)
        # print(type(data))
        return [data]

p = beam.Pipeline(options=pipeline_options)

# This gives me Pcollection of bytes (elements)
test = (p | 'test_r' >> beam.io.ReadFromText(known_args.input + '/' + 'test.bson', coder=coders.BytesCoder()
| 'test_parse' >> beam.ParDo(ParseBsontoJson())) - here I have problem

data = element.decode('latin-1').encode("utf-8")
data2 = json_util.dumps(data)
print(data2)

其中

元素

是BSON文件中的一行

我得到的是：

    "$type": "00"
}

我尝试了其他建议，例如类似的StackOverflow响应：

bson.decode_all(element)

或

但它不会将其转换为JSON视图

element.decode('latin-1')
