类型错误:没有编码的字符串参数 [英] TypeError: string argument without an encoding
问题描述
我想将 Json 的压缩 gzip 上传到 Google Storage.
我有这个代码:
import datalab.storage 作为存储导入 gzip路径 = 前缀 + '/orders_newline.json.gz'storage.Bucket('orders').item(path).write_to(gzip.compress(bytes(create_jsonlines(source)),encoding='utf8'),'application/json')
create_jsonlines(source)
是一个返回 Json Newline Delimited 的函数.
运行此代码给出:
TypeError: 没有编码的字符串参数
Python 文档 说格式是:bytes([source[, encoding[, errors]]])
我不确定我是否理解它,因为没有如何使用它的示例.
我也试过
bytes([(create_jsonlines(source))[,encoding='utf8']])
这给出:
SyntaxError: 无效语法
我正在运行 Python 3.5
您没有正确使用 bytes
函数.检查这个:
你可以试试:
bytes((create_jsonlines(source)), encoding='utf8')
encoding
是 bytes
函数的参数,您在该函数之外使用它.
I want to upload compressed gzip of Json into Google Storage.
I have this code:
import datalab.storage as storage
import gzip
path = prefix + '/orders_newline.json.gz'
storage.Bucket('orders').item(path).write_to(gzip.compress(bytes(create_jsonlines(source)),encoding='utf8'), 'application/json')
The create_jsonlines(source)
is a function that returns Json Newline Delimited.
Running this code gives:
TypeError: string argument without an encoding
The Python docs says the format is: bytes([source[, encoding[, errors]]])
I'm not sure I understand it as there is no example of how to use it.
I tried also
bytes([(create_jsonlines(source))[,encoding='utf8']])
This gives :
SyntaxError: invalid syntax
I'm running Python 3.5
You are not using the bytes
function correctly. Check this:
>>> a = "hi"
>>> bytes(a, encoding='utf8')
b'hi'
You can try:
bytes((create_jsonlines(source)), encoding='utf8')
encoding
is the argument of the bytes
function, and you are using it outside of that function.
