curl能否下载115的资源
1个300MB的资源,用迅雷下载(非115VIP),已经设置了原始线程1,但是平均速度只有10几KB,下到60%之时就提示错误。分析了一下URL地址规律,发现URL里的 &t=1368261625 是一个变量,估计115根据这个时间来处理下载过期事务。
用 Ultraediter 打开.td.cfg,修改了里面的&t=1368261625为当前时间,重新启动迅雷,发现文件被重新下载了(之前的60%木有了)。不知道如何修改迅雷,才可以使得修改了下载URL后可以继续前面的下载。(迅雷应该还有一个文件参数对比的方法,但是没有找到)
于是想到了用php curl下载115的资源(PHP可以任意修改URL地址),但是PHP的默认超时为30秒,如果set_time_limit(0);的话,如何判别115的资源地址已经失效,即这个PHP文件已经运行完毕?
打算用.bat文件,或者直接命令提示符DOS运行该php脚本。
问题:
1.用curl断点保存文件,会不会在第二次下载时,又重新从0%开始?
2.如果问题1可行的话,如果如何写代码,可以在一个长连接后,获知该PHP文件已经运行完毕?(这样重新运行.bat或者DOS进行断点下载)
PS:网上只有115上传类的代码,木有下载类的代码,大虾们帮忙挑战一下,可能的话,就是原创+精华帖,可以拿到CSDN博客里。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
