Python 获取空直播索引

Question

这是响应的样子

我想获取空行的索引，我试过了

response.index("\n\n")

但它不起作用。

有什么建议吗？

谢谢！

编辑：它给我这个

Traceback (most recent call last):
  File "test.py", line 15, in <module>
    test = response.index("\n\n")
ValueError: substring not found

这是我的完整代码：

import socket

server = "www.google.com"
server = socket.gethostbyname(server)
port = 80
request = "GET / HTTP/1.1\nHost: " + server + "\n\n"

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

sock.connect((server, port))
sock.send(request.encode())

response = sock.recv(4096)
print(response)

test = response.index("\n\n")

print(test)

编辑：看到你的整个代码后，很容易看出接收到的数据是编码的，你需要解码数据。

重要的部分是 response = sock.recv(4096).decode("utf-8")，它将字节数组转换为 python 中的字符串。

这段代码对我有用。

import socket

server = "www.google.com"
server = socket.gethostbyname(server)
port = 80
request = "GET / HTTP/1.1\nHost: " + server + "\n\n"

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

sock.connect((server, port))
sock.send(request.encode())

response = sock.recv(4096).decode("utf-8")
print(response)

test = response.index("\r\n\r")

print(test)
