请问php下载文件有关问题
请教php下载文件问题
目的:从远程链接处下载文件
问题:远程链接提供一个csv格式文件的下载,如:http://adscendmedia.com/campaigncsv.php,访问链接后浏览器提示下载,请问如何通过php代码直接下载此文件到服务器上?(这是后台运行的一个代码片段,所以无法来选择“另存为”方式下载的),各种常规下载方式都试过不行,有什么办法吗?
------解决方案--------------------
有两个可能的原因:一是有些网站不支持file_get_contents,fopen等函数的抓取。二是http://adscendmedia.com/campaigncsv.php转向了一个新的网址,这个网址才是要下载的文件。
对于第一个原因,可以尝试CURL函数,curl系列函数能够更好的模拟浏览器。
对于第二个原因,得到新的网址有两个方法。一个方法是在浏览器的下载功能里面,在文件下载过程中可以看到。而是用php的socket系列函数可以输出返回的header信息。
------解决方案--------------------
补充:也可以试试用socket系列函数抓取。

我看了一下,网址转向了https://adscendmedia.com/campaigncsv.php
注意是https !

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,
