web服务器怎么加载静态文件,2018-06-05静态文件web服务器

研究了一晚上的代码奉上：

#coding:utf-8

import socket

import re

# 定义一个常量用来接收客户端发起的文件请求地址

# 设置静态文件根目录

HTML_ROOT_DIR = "./html"

from multiprocessing import Process

def handle_client(client_socket):

"""处理客户端请求"""

# 获取客户端请求

request_data = client_socket.recv(1024)

print(request_data)

# 判断用户发来的请求

# 使用splitlines来切割不同行

request_lines = request_data.splitlines()

for line in request_lines:

print(line)

# GET / HTTP/1.1

request_start_line = request_lines[0]

file_name = re.match(r"\w+ +(/[^ ]*) ", request_start_line.decode("utf-8")).group(1)

# 通常把常量写在“左边”，变量写在右边，防止少写一个“=”不报错

if "/" == file_name:

file_name = "/index.html"

# 打开文件，读取内容(客户有可能请求图片资源：加上b)

try:

file = open(HTML_ROOT_DIR + file_name, "rb")

except IOError:

response_start_line = "HTTP/1.1 404 NOT FOUND\r\n"

response_headers = "Sever: My Sever\r\n"

response_body = "The file is not found!"

else:

file_data = file.read()

file.close()

# 构造响应数据

response_start_line = "HTTP/1.1 200 OK\r\n"

response_headers = "Sever: My Sever\r\n"

response_body = file_data.decode("utf-8")

response = response_start_line + response_headers + "\r\n" + response_body

print("response data:", response)

# 向客户端形响应数据

client_socket.send(bytes(response, "utf-8"))

# 关闭客户端连接

client_socket.close()

if __name__ == "__main__":

sever_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

sever_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

sever_socket.bind(("", 8090))

# 监听队列大小为128

sever_socket.listen(128)

# 为多个客户端服务

while True:

client_socket, client_address = sever_socket.accept()

print("[%s, %s]用户连接上了"%client_address)

handle_client_process = Process(target=handle_client, args = (client_socket,))

handle_client_process.start()

client_socket.close()

坑：没有把index.html放在“./html”里面，一直“not found”；要理解每一部分的含义，不能不求甚解

文件请求根目录
