OpenCV笔记之阈值(二值化)处理 一共有5个方法• cv2.THRESH_BINARY（超过阈值部分取最大值, 如超过了阈值127变为255）• cv2.THRESH_BINARY_INV（反转上面的，可以理解为上面的颜色反转）• cv2.THRESH_TRUNC （截断，大于阈值部分设置阈值，比如大于127的就设置为127）• cv2.THRESH_TOZERO (大于阈值部分保持不变，小于等于阈值的全为0)• cv2.THRESH_TOZERO_INV（反转上面的,小于阈值不变，大于等于阈值为0）ret,thresh1 = cv2.threshold(gray,127,255,cv2.THRESH_BINARY) ret,thresh2 = cv2.threshold(gray,127,255,cv2.THRESH_BINARY_INV) ret,thresh3 = cv2.threshold(gray,127,255,cv2.THRESH_TRUNC) ret,thresh4 = cv2.threshold(gray,127,255,cv2.THRESH_TOZERO) ret,thresh5 = cv2.threshold(gray,127,255,cv2.THRESH_TOZERO_INV)from matplotlib import pyplot as plt #thresh1在上面 titles = ['BINARY','BINARY_INV','TRUNC','TOZERO','TOZERO_INV'] images = [thresh1, thresh2, thresh3, thresh4, thresh5] for i in range(5): plt.subplot(2, 3, i+1) plt.imshow(images[i]) plt.title(titles[i]) plt.show() 滤波：#均值滤波 对一个3*3的像素颜色进行平均化 img=cv2.blur(img,(3,3)) #方框滤波 和均值滤波基本一样，-1是固定写法(颜色通道),normalize是处理像素颜色加起来不会越界 #不做处理的话 越界大于255就会用255来处理 img2=cv2.boxFilter(img,-1,(3,3),normalize=True) #高斯滤波的卷积核里的数值是满足高斯分布，相当于更重视中间的 img3=cv2.GaussianBlur(img,(3,3),1) # cv_show(img3) #中值滤波 取3*3范围内的中间数 img4=cv2.medianBlur(img,3) -

逆向之TLS指纹 大概过tls的思路1.最主要的 设置requests tls指纹 requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS2.看发tls带了啥，一般有 http1.1和User-Agent 有的要弄上这两个 有的没检测这requests发的tls默认写http1.0 要改源码为1.1教程：先用fd抓包，看每次发请求前都有一个Tunnel,甚至还有一把小锁的图标 点进来看 写的version 3.3(TLS/1.2) 这个就是了先搞TLS指纹吧图中的Ciphers就是指纹key 但是这个是假的用小鲨鱼 wireshark抓包点Client Hello然后Cipher Suites里面的Cipher Suite 显示有16个第一个去掉，复制后面15个就行了 复制先备用打开官方的密码表网址：https://www.openssl.org/docs/man1.1.1/man1/openssl-ciphers.html循环搜索你复制的N个 Cipher Suite 然后再把右边的value粘贴下来 如图只要右边的 最后以value:value:... 拼凑成一串再在python里import requests.packages.urllib3.util.ssl_ requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS = "TLS_AES_128_GCM_SHA256:xxx:xxx:xxx" #xxx粘贴你自己弄的那些第一步就完事了 可以尝试下能跑吗 不能就继续第二步右边的CONNECT 网址 HTTP1.1 和Headers{Connecton User-Agent} 都弄上 位置在源码 python/Lib/http/client.py//可以在python里直接写这个 import http.client http.client.HTTPConnection //然后ctrl+鼠标左键单击HTTPConnection 跳转到源码位置 //第886行的这个函数->_tunnel(self) //改成下面这样 headres按需扩展 def _tunnel(self): connect_str = "CONNECT %s:%d HTTP/1.1\r\n" % (self._tunnel_host, self._tunnel_port) connect_bytes = connect_str.encode("ascii") self.send(connect_bytes) self._tunnel_headers={ "Connection":"keep-alive", "User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.71 Safari/537.36" } for header, value in self._tunnel_headers.items(): header_str = "%s: %s\r\n" % (header, value) header_bytes = header_str.encode("latin-1") self.send(header_bytes) self.send(b'\r\n')改完了记得把import源码那个删除掉可以了，不写了，该干饭了

js逆向 扣代码-检测使用环境 通过代理对象的方式来修改get set代理代码const proxy = function(obj) { return new Proxy(obj, { set: (target, prop, val) => { console.log("SET>>>>", prop, prop, val) return Reflect.set(...arguments); }, get: (target, prop, r) => { console.log("GET>>>>", prop, prop, target[prop]) return target[prop] }, }) } //假设要对window进行监听 window = proxy(window)简单的获取第一层check_array=["document","window","navigator"]; function pr(check_array){ for(let a = 0;a < check_array.length; a++) { eval(check_array[a]+`=new Proxy(`+check_array[a]+`,{ get:function(k,v){ console.log("获取了",check_array[a],"里面的",v) return k[v]; } })`) } } pr(check_array)check数组可以添加更多的可能被检测的东东然后放js最上面跑一下方法2 深度递归30层(function () { function set_traverse_object(tarrget, obj, recursion_layers) { recursion_layers -= 1; console.log(); for (let prop in obj) { const value = obj[prop]; const tg_name = `${tarrget}.${prop.toString()}`; const value_type = get_value_type(value); if (value && value_type === "object" && recursion_layers >= 1) { set_traverse_object(tg_name, value, recursion_layers); continue } if (value && value.toString() !== '[object Object]') { console.log(`setter hook->${tg_name}; value-> ${value}; typeof-> ${value_type}`); continue } console.log(`setter hook->${tg_name}; value-> ${value}; typeof-> ${value_type}\n`) } } function new_handel(target_name, obj, number) { return new Proxy(obj, my_handler(target_name, number)) } function get_value_type(value) { if (Array.isArray(value)) { return 'Array' } return typeof value; } function my_handler(target_name, number) { return { set: function (obj, prop, value) { const value_type = get_value_type(value); const tg_name = `${target_name}.${prop.toString()}`; if (value && value_type === "object") { set_traverse_object(tg_name, value, number) } else { console.log(`setter hook->${tg_name}; value-> ${value}; typeof-> ${value_type}`) } return Reflect.set(obj, prop, value); }, get: function (obj, prop) { const tg_name = `${target_name}.${prop.toString()}`; const value = Reflect.get(obj, prop); let value_type = get_value_type(value); if (value && value_type === 'object') { return new_handel(tg_name, value, number) } console.log(`getter hook->${tg_name}; value-> ${value}; typeof-> ${value_type}\n`); return value } } } window = new Proxy(window, my_handler(Object.keys({window})[0], 30)); }());
