Question

由于我是编程新手，我可能还没有检测到其他错误，所以如果你发现任何菜鸟错误或不好的风格请指出。我正在尝试实现一个简单的Web服务器，但在服务器创建HTTP响应消息的部分继续收到缩进错误，该消息包含前面标题行的请求文件。

from socket import *
import sys

host = 'localhost'
serverPort = int(sys.argv[1])
serverSocket = socket(AF_INET, SOCK_STREAM)
serverSocket.bind((host,serverPort))
serverSocket.listen(1)

while True:
    connectionSocket, addr = serverSocket.accept()

    try:
        #if received correct stuff
        File_Wanted = connectionSocket.recv(1024)
        File_Name = File_Wanted.split()[1]
        #open and read line in index.htm
        File = open('index.htm','r')
        output = File.read()
        #should I close it here or somewhere else?
        File.close()

        #take care of header first 
        connectionSocket.send('HTTP/1.0 200 OK\r\n')

        #looks good, then send to client(browser)
        for i in range(0, len(output)):
        connectionSocket.send(output[i]) 
        connectionSocket.close()


    IOError:
    #Send response message for file not found
        connectionSocket.send('404 Not Found')                       
    #Close client socket       
        connectionSocket.close()                            


serverSocket.close()

当我建立崇高时，我得到了。

connectionSocket.send(output[i]) 
^

IndentationError：期待一个带有标号的块

Python使用空格来定义块，你需要在for语句之后缩进行：

for i in range(0, len(output)):
    connectionSocket.send(output[i]) 
    connectionSocket.close()

并且在检查错误之前需要except语句：

except IOError:

'缩进错误 - 处理标题时预计会出现缩进块'
