curl保存cookies的问题

Jun 23, 2016 pm 01:19 PM

有的网站会用不同的域名设置COOKIE,这样好像CURL就会漏掉一些COOKIE。例如CURL访问网站www.xxx.com首页时,它会立即设置一个属于xxx.com的COOKIE,在首页填写用户名确定后转到www.xxx.com/next.php,这时会设置一个属于www.xxx.com的COOKIE。请问这两个COOKIE要怎么成功获取呢?

CURLOPT_COOKIE
设定HTTP请求中“Set-Cookie:”部分的内容。
CURLOPT_COOKIEFILE
包含cookie信息的文件名称,这个cookie文件可以是Netscape格式或者HTTP风格的header信息。
CURLOPT_COOKIEJAR
连接关闭以后,存放cookie信息的文件名称

谢谢你的回复

访问首页时,首页会生成属于xxx.com的COOKIE,CURL取不到这个COOKIE:

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'http://www.xxx.com');
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $contents = curl_exec($ch);
    curl_close($ch);

填写用户名确定后,转到第二页时,会生成属于www.xxx.com的COOKIE,CURL可以成功取得这个COOKIE:

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'http://www.xxx.com/next.php');
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
    curl_setopt($ch, CURLOPT_COOKIEFILE, $cookieFile);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $contents = curl_exec($ch);
    curl_close($ch);

为什么CURL访问http://www.xxx.com的时候,www.xxx.com会生成一个属于xxx.com的COOKIE呢?这会不会就是CURL取不到COOKIE的原因?

具体情况要具体分析,你最好给出真实的 url

已经解决了,原来是JS设置的,谢谢你。还有一个问题想问你一下:curl_exec()之后就立即curl_close()和curl_exec()之后暂停5分钟再curl_close(),那对于被curl的网站来说,会有什么不同呢?

没有什么不同

非常感谢!

楼主您好!我好像遇到了和你一样的问题,使用CURL库时request里的cookies好像缺少了一部分,请问你是怎么解决的?

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,

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.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
