(大神)php curl验证码模拟登录问题

Jun 20, 2016 pm 12:59 PM

function curlLogin($login_url, $cookieFile_code, $cookieFile_login, $loginParams, $target_url)	{	    $ch = curl_init($login_url);	    curl_setopt($ch,CURLOPT_COOKIEFILE, $cookieFile_code); //验证码session值上传	    curl_setopt($ch,CURLOPT_COOKIEJAR, $cookieFile_login); //获取登录cookie		curl_setopt($ch, CURLOPT_HEADER, 1);	    curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);	    curl_setopt($ch,CURLOPT_POST, 1);	    curl_setopt($ch,CURLOPT_POSTFIELDS, $loginParams); //提交查询信息	    curl_exec($ch);	    curl_close($ch);	    $ch = curl_init($target_url);	    curl_setopt($ch,CURLOPT_COOKIEFILE, $cookieFile_login);	    curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);	    $content = curl_exec($ch);	    if(curl_errno($ch)){	    	return curl_error($ch);	    }	    curl_close($ch);	    return $content;	}
Copy after login

我在尝试模拟登录一个带有验证码的的网站,验证码我是使用人工识别的方式,在将本地存有session值的cookie和人工识别的验证码模拟登录后,我想要获取保持登录的cookie,可是获取到的却是验证码的cookie,我用的就是下面两行代码,请大神为我解答一下怎么修改呢?
  curl_setopt($ch,CURLOPT_COOKIEFILE, $cookieFile_code); //验证码session值上传  curl_setopt($ch,CURLOPT_COOKIEJAR, $cookieFile_login); //获取保持登录的cookie
Copy after login

要分两步,先获取验证码的cookies,
然后提交后再获取登陆后的cookies。

根本没看我发的内容,我都说了我已经拿到验证码cookie了,现在是在获取登录的cookie。

你是按一下步步骤做的吗?(你只给个函数不能说明什么)
1、访问表单页(sessionid可能在这里就有)
2、读取验证码图片到识别表单
3、接收提交的验证码数据
4、将综合数据提交到表单目标页

除 3 外,每步都要有
curl_setopt($ch,CURLOPT_COOKIEFILE, $cookieFile_code);
curl_setopt($ch,CURLOPT_COOKIEJAR, $cookieFile_login);

显然这些工作是不可能在一个函数里完成的
尽管写的好的话,可以只用一个函数,但必然是多次调用的

我摸索中成功登录上去了,我模拟登录的系统比较奇怪,它至始至终的cookie值只有一个,就是验证码生成时产生的随机session,我将该我没用到curl_setopt($ch,CURLOPT_COOKIEFILE, $cookieFile_code);操作去提交cookie,我将里面的session值用正则匹配出来后,附加到header上去提交,其中我模拟登录失败的原因可能是因为服务器判断了来源页,没有设置虚拟来源页的登录都会被拒绝。另外说一下,我模拟登录的是方正的教务处系统。希望我的失败经验对其他人能有帮助。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.
