使用python下载图片(福利) 重要的事情说三遍!!! 觉得这篇文章好的 就点点关注哦 觉得这篇文章好的 就点点关注哦 觉得这篇文章好的 就点点关注哦
刚学python 没多久， 代码处处是漏洞，也希望各位大佬理解一下
爬出来的图片...
使用的 是 https://www.tianapi.com/ 接口下的 美女图片...
(需要自己注册一个账号， 得到key 这样才能调用 这个接口)
但是今天看天行 好像炸了
下面开始 撸代码l
爬图片的思路
第一 获取url
第二 分析数据信息，得到有用数据
第三 请求每次 得到的信息
第三 撸 下来
（大致就是这么几块）
下面开始 写代码，,, 假如没安装的 python 环境和编辑器的话，自己百度哦（当初弄这个的时候没想到写博客，如果不会，也可以叫我帮忙）
本次需要用到两个库文件
import requests
import json
运行 输入 pip install requests
就ok了
1 url="http://api.tianapi.com/meinv/?key=你的key&num=50" 2 req=requests.get(url) 3 print(req) #查看状态
4#num =50 (每次最多50条信息 否则的话 就只会显示10条信息 ，不要弄错了)
5
将会得到 这个 如果出现这个 表示 连接成功
6 html=req.text
7 print(“=====”+html)
打印出来下面的数据
很明显
他是一个字典类型然后里面又有列表，列表里面又包含字典

finished with exit code 0
但是 它的类型现在目前是str （C#叫做string） 我们必须要转换一下
dict1=json.loads(html) # 格式化4 调用json 的模块 然后 调用 loads （这里不使用load）打印一下类型 发现已经变成字典类型了
接下来 我们研究一下 刚刚打印出来的数据
发现了 newlist：[{XXXXXX}]
我们一层一层解析出来
dict1_data=dict1["newslist"]
print(dict1_data)
[{'ctime': '2017-01-24 16:00', 'title': '花花', 'description': '华声美女', 'picUrl': 'http://image.hnol.net/c/2017-01/23/15/20170123152957561-1876615.jpg'。。。。。。'url': 'http://bbs.voc.com.cn/mm/meinv-7641359-0-1.html'}]
变成这样就好办了
我们自己 请求图片地址，然后每次请求都把图片写下来
但是大家注意到了没有， 解析出来的 东西 并不是仅仅是图片， 而且还有文字
{'ctime': '2017-01-24 16:00', 'title': '花花', 'description': '华声美女', 'picUrl': 'http://image.hnol.net/c/2017-01/23/15/20170123152957561-1876615.jpg'
但是我们要的只要图片 不要其他的
这里，我们又要再一次解析...
但是 你看见了 我们的图片连接 有很多啊
那我岂不是要请求很多次
这个时候 我们使用 for循环 来请求
然后下载保存
for list_data in dict1_data:
#print(list_data["picUrl"]) 图片 仅仅是 要图片地址，不要其他东西
for reqs_data in reqs:
f.write(reqs_data)
f.close() #关闭
这样子，我们已经把图片下载下来了
可是我们不知道 什么时候下载完了 ，你也不可能一直盯着电脑
我们来个提示
for list_data in dict1_data:
#print(list_data["picUrl"]) 图片 仅仅是 要图片地址，不要其他东西
reqs=requests.get(list_data["picUrl"])
print(reqs) #每次请求
f=open('./image/'+‘ssss.jpg’,"wb")
for reqs_data in reqs:
f.write(reqs_data)
f.close() #关闭
print("图片已经下载完了哦！！！")
这样子 图片下载完毕之后 我们就知道已经完成了
但是 这里也会有个问题
如果你运行的话，只会有一张图片
因为 你一直请求，然后写入到 ssss.jpg ...
这里 你不能写死了 ，我们换一下，注意看看图片的连接名字，发现他们的地址都不一样，名字也不一样
http://sd/sd//sd/.01.jpg 类似这样...
我们能不能也这样子呢
再改一下代码
for list_data in dict1_data:
#print(list_data["picUrl"]) 图片 仅仅是 要图片地址，不要其他东西
reqs=requests.get(list_data["picUrl"])
print(reqs) #每次请求
strimg=list_data["picUrl"].split("/")[-1] #
f=open('./image/'+strimg,"wb")
for reqs_data in reqs:
f.write(reqs_data)
f.close() #关闭
print("图片已经下载完了哦！！！")
运行一下
这个错误呢 是我们 抓的太频繁了 ，，， 浏览器 拒绝了本次请求。。重新运行一下就行了（主要是这里没写反扒...）
下面我们重新运行一下
当然在这里 觉得代码太多 看着烦，可以写个函数 封装一下哦
就是这样哦 ，，，一不小心就爬了几百张图片了... 我只会爬这种哦.. 其他的什么都不会（一脸严肃）
