我们之前爬取有道翻译的翻译内容时，我们通过fiddler抓取url地址时，我们发现如果我们直接将相关参数传入，会报错。只是因为，某些参数是变化的。因此，我们需要解读JS文件，取得相关参数的生成算法，利用python生成参数，再传入。
我们继续以有道翻译为例讲解如何获取相关参数的生成算法，并利用python生成参数。
首先，我们使用fiddler抓取翻译所需要的全部参数，
data = {
"i": keyword, # 翻译内容
"from": "AUTO", # 源语言，固定值
"to": "AUTO", # 目标语言，固定值
"smartresult": "dict", # 智能结果，固定值
"client": "fanyideskweb", # 客户端，固定值
"salt": res['salt'], # 加密用的盐，这个值变化
"sign": res['sign'], # 签名字符串，这个值变化
"ts": res['ts'], # 毫秒时间戳，这个值变化
"bv": res['bv'], # 未知值，这个值变化
"doctype": "json", # 文档类型，固定值
"version": "2.1", # 版本，固定值
"keyfrom": "fanyi.web", # 键的来源，固定值
"action": "FY_BY_CLICKBUTTION", # 操作动作，固定值
}
通过分析参数我们发现需要获取salt、sign、ts和bv参数的算法。
我们进入有道翻译页面，右键“检查”-“网络”找到所有的js文件，依次进入并搜索salt、sign。
经过搜索，我们发现fanyi.js文件中有salt和sign，将fanyi.js下载并格式化。在格式化后的js文件中搜索salt，我们可以找到这样一个函数，
function (e, t) {
var n = e("./jquery-1.7"); // e为要翻译的内容
e("./utils");
e("./md5");
var r = function (e) {
var t = n.md5(navigator.appVersion), // t参数为经过md5加密后的浏览器版本
r = "" + (new Date).getTime(), // r参数为时间戳
i = r + parseInt(10 * Math.random(), 10); // i参数为时间戳加0-10之间随机整数
return {
ts: r, // ts参数为r
bv: t, // bv参数为t
salt: i, // salt参数为i
// sign参数为md5加密
sign: n.md5("fanyideskweb" + e + i + "mmbP%A-r6U3Nw(n]BjuEU")
}
};
t.recordUpdate = function (e) {
var t = e.i,
i = r(t);
n.ajax({
type: "POST",
contentType: "application/x-www-form-urlencoded; charset=UTF-8",
url: "/bettertranslation",
data: {
i: e.i,
client: "fanyideskweb",
salt: i.salt,
sign: i.sign,
ts: i.ts,
bv: i.bv,
tgt: e.tgt,
modifiedTgt: e.modifiedTgt,
from: e.from,
to: e.to
},
success: function (e) {
},
error: function (e) {
}
})
},
经过分析js代码，我们可以获取salt、sign、ts和bv参数的算法。我们下面使用python生成这些参数，
import hashlib
import time
import random
def handlerSignSalt(e):
navigator_appVersion = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36 Edg/83.0.478.56"
t = hashlib.md5(navigator_appVersion.encode('utf-8')).hexdigest()
r = str(int(time.time() * 1000)) # 当前毫秒的时间戳
i = r + str(random.randint(1, 10)) # 盐值
return {
'ts': r,
'bv': t,
'salt': i,
'sign': hashlib.md5(str("fanyideskweb" + e + i + "mmbP%A-r6U3Nw(n]BjuEU").encode('utf-8')).hexdigest(),
}
这样，我们就获取到了所有的参数，下面对有道翻译进行爬取，完整代码如下，
import requests
import hashlib
import time
import random
# e为要翻译的内容
def handlerSignSalt(e):
navigator_appVersion = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36 Edg/83.0.478.56"
t = hashlib.md5(navigator_appVersion.encode('utf-8')).hexdigest()
r = str(int(time.time() * 1000)) # 当前毫秒的时间戳
i = r + str(random.randint(1, 10)) # 盐值
return {
'ts': r,
'bv': t,
'salt': i,
'sign': hashlib.md5(str("fanyideskweb" + e + i + "mmbP%A-r6U3Nw(n]BjuEU").encode('utf-8')).hexdigest(),

有些网站会通过给关键字自定义字体，然后使用字体code名替换内容来使爬网站的人爬取无效字符，进而阻止一部分人爬取网站。例如，我们打开实习僧网站的其中一页，查看代码。我们看到其中的数字无法直接读取。
为了解决这个问题，我们需要对字体进行解析。
考虑网页渲染性能，通常把自定义的字体编码成base64，因此，我们可以在网页源代码中中查找@font-face获取编码再用python进行解码然后保存到本地，
import base64
from fontTools.ttLib import TTFont
headers = {
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36 Edg/83.0.478.56",
}

# 解码base64字体文件
font_bytes = base64.b64decode(fontFace)
# 保存到本地文件
with open("shixiseng.ttf", "wb") as fp:
fp.write(font_bytes)
之后，将字体文件转成xml，需要安装fontTools库，
pip install fontTools
字体文件转成xml，
from fontTools.ttLib import TTFont
baseFont = TTFont("shixiseng.ttf")
baseFont.saveXML('shixiseng.xml') # 将字体文件保存为xml文件
打开xml文件，我们可以看到有字体的cmap和glyf。其中，cmap中存放的是code和name之间的关系，glyf中存放的是字体形状和name的关系。
code是显示在网页中的代码，网站开发者可能会通过修改code来干扰我们爬取。但是字体最终的形状是不变的，我们可以通过分析字体，得出每个字体形状对应的文字，然后保存到一个字典中。以后再请求网页的时候，就进行反向解析，先获取字体的形状，再通过字体形状反向获取代号所对应的具体文字内容。
代码如下，
