Matlab爬虫获取王者荣耀英雄皮肤
精选 原创前言:周末闲来无事,玩了几局王者荣耀,突发奇想怎么获取到王者荣耀里面的英雄皮肤,本期分享一下如何通过matlab爬虫批量提取王者荣耀的英雄皮肤
关键字:王者荣耀、爬虫、Matlab
首先在度娘上找到王者荣耀的英雄主页
https://pvp.qq.com/web201605/herolist.shtml
通过chrome浏览器的F12,找到获取英雄的调用方法。
双击这个herolist.json,通过Notepad++打开可以看到里面对应的英雄详情
在matlab通过urlread函数获取到英雄列表情况,由于获取到的数据为char,需要转换为json格式,通过jsondecode函数实现转换
对每个英雄提取对应的ename、cname和skin_name变量,
下面开始要提取对应的图片,例如任意选择一个英雄,网址为:
https://pvp.qq.com/web201605/herodetail/508.shtml
右击选择图片-->检查,
可以看到对应的图片路径:
https://game.gtimg.cn/images/yxzj/img201606/heroimg/508/508-smallskin-2.jpg
根据上面的网址,可以得到对应的图片路径格式为:
https://game.gtimg.cn/images/yxzj/img201606/heroimg/{hero_number
}/{hero_number}-smallskin-{hero_skin_number}.jpg
通过webread函数提取到对应的图片,然后获取的图片通过imwrite保存成jpg文件。
通过urlread和webread在网络不好的情况下,可能会出现报错,所以通过try catch避免程序异常报错。对于每个英雄都单独保存在对应的名称文件夹下,通过mkdir创建文件夹。
完整的代码:
jsnotallow=jsondecode(herolist);[row, col] = size(jsonData);hero_name = cell(row,1);hero_number = cell(row,1);hero_skin_number = cell(row,1);for i = 1:row hero_name{i} = jsonData{i,1}.cname; hero_number{i} = jsonData{i,1}.ename; try skin_name = strsplit(jsonData{i,1}.skin_name, '|'); hero_skin_number{i} = length(skin_name); catch hero_skin_number{i} = 1; endendsavepath = 'C:\Users\xxx\Documents\MATLAB';for i = 1:row file_name = hero_name{i}; file_path_name = strcat(savepath,'\',file_name); file_path_name_ = strcat(file_path_name,'\'); mkdir(file_path_name_); for k = 1:hero_skin_number{i} onehero_link = strcat('http://game.gtimg.cn/images/yxzj/img201606/skin/hero-info/' ... , num2str(hero_number{i}), '/', num2str(hero_number{i}), '-bigskin-', num2str(k),'.jpg'); try image = webread(onehero_link); catch disp(['获取英雄',hero_name{i},'图片失败,请再次重试']) end imwrite(image,strcat(file_path_name_, num2str(k), '.jpg')); endend
最后提取的结果如下

附上Python版本(推荐):
url = 'https://pvp.qq.com/web201605/js/herolist.json'herolist = requests.get(url) # 获取英雄列表json文件
herolist_json = herolist.json() # 转化为json格式hero_name = list(map(lambda x: x['cname'], herolist.json())) # 提取英雄的名字hero_number = list(map(lambda x: x['ename'], herolist.json())) # 提取英雄的编号hero_skin_number = []for i in herolist.json(): try: hero_skin_number.append(len(i['skin_name'].split("|"))) except KeyError: hero_skin_number.append(1)
# 下载图片def downloadPic(): i = 0 for j in hero_number: # 创建文件夹 os.mkdir("./" + hero_name[i]) # 进入创建好的文件夹 os.chdir("./" + hero_name[i]) i += 1 for k in range(1, hero_skin_number[i - 1] + 1): # 拼接url onehero_link = 'http://game.gtimg.cn/images/yxzj/img201606/skin/hero-info/' + str(j) + '/' + str( j) + '-bigskin-' + str(k) + '.jpg' print(onehero_link) im = requests.get(onehero_link) # 请求url if im.status_code == 200: open(str(k) + '.jpg', 'wb').write(im.content) # 写入文件 os.chdir("../")
downloadPic()
