    这是一个创建于 2031 天前的主题,其中的信息可能已经有所发展或是发生改变。

    使用 paramiko 完成 执行远程 shell,实时获取结果

    参考了这个: https://www.v2ex.com/t/431535

    完成了

    def line_buffered(f):
        line_buf = ""
        while not f.channel.exit_status_ready():
            line_buf += f.read(1)
            if line_buf.endswith('\n'):
                yield line_buf
                line_buf = ''
    
    stdin, stdout, stderr = ssh.exec_command(shell)
                print logfile
    
                logfile = "static/logs/{0}".format(logfile)
                print logfile
                myfile = open(logfile, "w")
                for l in line_buffered(stdout):
                    print l.decode("utf-8")
                    myfile.write('ddd')
                    myfile.write(l.decode("utf-8"))
                    myfile.flush()
                myfile.close()
    

    可以非阻塞实时返回,但有个问题,我的 shell 脚本中带有中文,就回报错

        content_type, content_encoding, content = self._encode(data)
    

    我是 python2.7 的,该加 .decode("utf-8")都加了

    如果是直接使用平常方式,中文就能正常打印

    result = stdout.read(), stderr.read()
                
                for i in result:
                    print 
    
    

    这个编码要怎么破,不要说换 python3.。
