Question

我试图比较来自Pyserial的2个字符串，另一个是硬编码的消息。它们似乎是相同的，但由于某种原因，函数wait_prompt只返回0。

 def wait_prompt(device, msg):
        device.write("\n\n")
        device.flush()

        msg = msg + "\n"
        output = device.readline()

        print("\n")
        print("Looking for: " + msg + "|end")
        print("CLI shows: " + output + "|end")

        if output == msg:
                return 1
        return 0

def initialize_router(device):

        print ("Router connected on port " + port[0])

        while wait_prompt(device, "Would you like to enter the initial configuration dialog? [yes/no]: ") == 0:
                time.sleep(1)

        device.write("no\n")
        device.flush()

        while wait_prompt(device, "Line protocol on Interface Vlan1, changed state to up") == 0:
                time.sleep(1)

        time.sleep(2)
        device.write("\n")
        device.flush()

虽然我在这里，有没有更好的方式通过consol电缆与终端进行通信？我看到了pexpect，但它似乎不能连续工作。

解

问题是输出结束时返回\ r \ n \ r \ n而不仅仅是\ n就像我期待的那样。我修改了代码，只搜索字符串的一部分来验证测试。这是：

def wait_prompt(device, msg):
        device.write("\n\n")
        device.flush()
        output = device.readline()

        if msg in output:
                return 1
        return 0

def initialize_router(device):

        print ("Router connected on port " + port[0])

        while wait_prompt(device, "[yes/no]:") == 0:
                time.sleep(1)

        device.write("no\n")
        device.flush()

        while wait_prompt(device, "Line protocol on Interface Vlan1, changed state to up") == 0:
                time.sleep(1)

        time.sleep(2)
        device.write("\n")
        device.flush()

Python比较字符串
