selenium+pynput破解滑块验证码

目前很多网站都会采用滑块验证码作为反爬,由于selenium的特征值太多，很容易被识别出来,因此需要更加底层的技术–pynput模拟鼠标的点击、拖动行为

pynput.mouse：包含控制和监控鼠标或者触摸板的类。
pynput.keyboard：包含控制和监控键盘的类。

核心代码实例化一个pynput.mouse的类mouse来控制鼠标
mouse.press(Button.left) #按下鼠标
mouse.move() #拖动鼠标
mouse.release(Button.left) #松开鼠标

控制了鼠标下一步就是计算滑动轨迹,这里先是把传入的滑动距离+50,确保划出范围,然后分成两步[0.7,0.3]的比例，整个路程先加速，再减速，再加速，再减速

# 构造滑动轨迹
def get_trace(distance):
	'''
	计算滑动
	'''
	lu = [0.7,0.3]
	# 创建存放轨迹信息的列表
	trace = []
	# 设置加速的距离
	#distance += 20
	faster_distance = distance+50

	print('--------开始计算滑动轨迹-------')
	for i in lu:
		the_distance = i*faster_distance
		# 设置初始位置、初始速度、时间间隔
		start, v0, t = 0, 0, 0.2
		# 当尚未移动到终点时
		while start < the_distance:
			# 如果处于加速阶段
			if start < the_distance:
				# 设置加速度为2
				a = 30
			# 如果处于减速阶段
			else:
				# 设置加速度为-3
				a = -30
			# 移动的距离公式
			move = v0 * t + 1 / 2 * a * t * t
			# 此刻速度
			v = v0 + a * t
			# 重置初速度
			v0 = v
			# 重置起点
			start += move
			# 将移动的距离加入轨迹列表
			trace.append(round(move,2))
	print(trace)
		# 返回轨迹信息
	return trace

好了齐活上代码
