【python】使用paramiko上传文件到Linux并且解压

思路是，使用zipfile对文件进行压缩，之后使用paramiko提供的SFTPClient()上传文件，之后使用paramiko的SSHClient()执行Linux命令操作文件

import os
    import zipfile
    import paramiko
    
    # 使用zipfile压缩文件
    def zip_code(dir_name, zip_name):
        file_list = []
        if os.path.isfile(dir_name):
            file_list.append(dir_name)
        else:
            for root, dirs, files in os.walk(dir_name):
                for name in files:
                    file_list.append(os.path.join(root, name))
        zf = zipfile.ZipFile(zip_name, "w", zipfile.ZIP_DEFLATED)
        for tar in file_list:
            arc_name = tar[len(dir_name):]
            zf.write(tar, arc_name)
        zf.close()
    
    # 使用zipfile解压文件（这是直接在本地解压）
    # def unzip_file(zip_file_name, unzip_dir):
    # zf = zipfile.ZipFile(zip_file_name)
    # file_list = zf.namelist()
    # for file in file_list:
    # zf.extract(file, unzip_dir)
    # zf.close()
    
    
    def upload_code(host, port, username, pwd, local_file, target_path, target_file_name):
        transport = paramiko.Transport((host, port))
        transport.connect(username=username, password=pwd)
    
        sftp = paramiko.SFTPClient.from_transport(transport)
        sftp.put(local_file, target_path + target_file_name)
        client = paramiko.SSHClient()
        client._transport = transport
        cmd_ls = "ls -l " + target_path + target_file_name
        _, stdout, stderr = client.exec_command(cmd_ls)
        if not stdout.read().decode('utf-8'):
            print("失败: ", stderr.read().decode('utf-8'))
            return
        # 这里使用unzip解压，但是zipfile压缩的时候对中文不友好，所以unzip解压需要指定CP936编码
        cmd = "cd " + target_path + " && sudo rm -rf web_code/* && unzip -O CP936 " + target_file_name + " -d web_code/ && rm " + target_file_name
        print("cmd: ", cmd)
        _, stdout, stderr = client.exec_command(cmd)
        print("stdout:", stdout.read().decode('utf-8'))
        print("stderr:", stderr.read().decode('utf-8'))
        print("finish")
    
    
    def start():
        username = "root"
        pwd = "12345"
        host = "localhost"
        port = 22
        target_file_name = "dist.zip"
        local_file = "./{}".format(target_file_name)
        target_path = "/test/"
        zip_code(r"D:\工作", "./{}".format(target_file_name))
        upload_code(host, port, username, pwd, local_file, target_path, target_file_name)
        input()
    
    
    if __name__ == '__main__':
        start()

需要注意的是，使用unzip解压的时候即使指定了CP936编码，但还是会有部分中文显示乱码
