【Error】 json file 不能读取的解决办法 TypeError: Input string must be text, not bytes

最开始是用

with open(path) as f: data = json.loads(f)

然后报错TypeError: Input string must be text, not bytes

尝试1，加上解码:

with open(path, encoding='utf-8') as f: data = json.loads(f)

仍报错TypeError: Input string must be text, not bytes

尝试2，读取每行:

with open(path, encoding='utf-8') as f: data = [json.loads(line) for line in f]

报错JSONDecodeError: Expecting property name enclosed in double quotes or '}'

这时候，我们知道，肯定是json file里面有些“非法”字符需要删除。

最终尝试，使用nested replace去除“非法”字符：

# nested replace() with open(gentle_file, encoding='utf-8') as f: tmp = f.read().replace('\t','').replace('\n','').replace(',}','}').replace(',]',']') data = json.loads(tmp)

成功！
