Python-如何访问 zip 文件中的文件夹并写入其中

Question

您好，我正在尝试从 z.jar 访问文件。文件结构类似于 z.jar\org(文件夹)。这里 Org 是一个文件夹，我试图访问 z.jar 内的 org 文件夹并尝试写一些东西。有人可以帮我吗？

import zipfile
def show_jar_classes(jar_file):
    """prints out .class files from jar_file"""
    zf = zipfile.ZipFile(jar_file, 'w')
    try:
        #Code to write inside org folder in inside z.jar
        zf.write('India.txt')
    finally:
        zf.close()

jar_file='D:/pyt/z.jar'
show_jar_classes(jar_file)

Answer 1

调整您的代码。使用 writestr 对我有用:

import zipfile, os

def show_jar_classes(jar_file):
    """prints out .class files from jar_file"""
    zf = zipfile.ZipFile(jar_file, 'w')
    try:
        #Code to write inside org folder in inside z.jar
        filename = 'Org\\India.txt' # name of the file
        fcontent = b'India is a great country' # content
        zf.writestr(filename,fcontent,zipfile.ZIP_DEFLATED)

    finally:
        zf.close()

jar_file = 'D:/pyt/z.jar'
show_jar_classes(jar_file)
