getCodeChar 并不是一个标准的 JavaScript 方法或函数。可能你是指 charCodeAt 方法,这是一个用于获取字符串中特定位置字符的 Unicode 编码的方法。 基础概念 charCodeAt 方法返回在指定的位置的字符的 Unicode 编码。其语法如下: 代码语言:txt 复制 str.charCodeAt(index) i
response = requests.get(url, headers=headers, params=params) print(response.text) # 关闭会话 session.close() # 输出结果:{"code":200,"data":null,"msg":"校验通过"} 好了,走到这里,最简单的验证码鉴权处理也就走完...
