中文dump后写入json文件无法显示中文

If ensure_ascii is True (the default), all non-ASCII characters in the output are escaped with \uXXXX sequences, and the result is astrinstance
consisting of ASCII characters only. Ifensure_ascii is False, some chunks written to
fp may be
unicode instances. This usually happens because the input contains unicode strings or theencoding parameter is used. Unless fp.write() explicitly understands

unicode(as in
codecs.getwriter()) this is likely to cause an error.

json dump有一个ensure_ascii参数，当它为True的时候，所有非ASCII码字符显示为\uXXXX序列，只需在dump时将ensure_ascii设置为False即可，此时存入json的中文即可正常显示。

例如：

json.dump(f, ensure_ascii=False)
