問(wèn)題描述

Python 3.6中，網(wǎng)頁(yè)信息解析失敗，試了很多種編碼，查看網(wǎng)頁(yè)的編碼方式也是utf-8。錯(cuò)誤信息：’utf-8’ codec can’t decode byte 0x8b in position 1: invalid start byte?還有就是第一個(gè)print終端里打印出來(lái)的unicode內(nèi)容是[b’x1fx8bx08x00x...]這種格式的，之前也有過(guò)這種情況，一個(gè)print打2個(gè)變量，就是b’x, 如果分來(lái)2行打又變回了漢字。是因?yàn)槭裁丛蚰兀?/p>

# -*- coding: utf-8 -*-import json , sqlite3import urllib.requesturl = (’http://wthrcdn.etouch.cn/weather_mini?city=%E4%B8%8A%E6%B5%B7’)resp = urllib.request.urlopen(url)content = resp.read()print(content)print(type(content))print(content.decode(’utf-8’))

問(wèn)題解答

看了一下網(wǎng)站返回的是gzip壓縮過(guò)的數(shù)據(jù)，所以要進(jìn)行解碼

# coding=utf-8from io import BytesIOimport gzipimport urllib.requesturl = (’http://wthrcdn.etouch.cn/weather_mini?city=%E4%B8%8A%E6%B5%B7’)resp = urllib.request.urlopen(url)content = resp.read() # content是壓縮過(guò)的數(shù)據(jù)buff = BytesIO(content) # 把content轉(zhuǎn)為文件對(duì)象f = gzip.GzipFile(fileobj=buff)res = f.read().decode(’utf-8’)print(res)

requests不好用嗎？

建議用requeset，代碼如下：

import requestsr = requests.get(’http://wthrcdn.etouch.cn/weather_mini?city=%E4%B8%8A%E6%B5%B7’)print(r.text)回答4：

不是字符編碼問(wèn)題, 你看看你請(qǐng)求的 Respont headers

Status Code: 200 OK Access-Control-Allow-Headers: * Access-Control-Allow-Methods: * Access-Control-Allow-Origin: * Cache-Control: must-revalidate, max-age=300 Connection: Keep-Alive Content-Encoding: gzip Content-Length: 443 Date: Fri, 10 Mar 2017 03:20:46 GMT Fw-Cache-Status: hit Fw-Via: HTTP MISS from 58.59.19.99, DISK HIT from 183.131.161.27 Server: Tengine/2.1.2

是gzip, 如果用標(biāo)準(zhǔn)庫(kù)的東西, 還需要把gzip 給解開(kāi)
