网站是nginx+php,有个接口是接受用户上传的图片,当接口并发量大的时候会报nginx warn
<code>a client request body is buffered to a temporary file /var/cache/nginx/client_temp/***** </code>
查了一下资料,应该是客户端请求内容大于缓冲区,请求内容被写入临时文件 一般用户上传的图片都有1M左右,是否可以
<code>client_body_buffer_size 1024k </code>
疑问:这样是否就是将请求保存在内存中?那么请求量大的时候会不会因为内存不足造成更大的问题
最近服务器负载会飙高,估计也和这个接口有关系,上传图片比较慢导致大量php进程在处理,是否有其它替代方案?

如果你设定了最大的buffersize,那么当这个maxbuffer_size小于可以使用的内存大小时,是不会报内存不足的,这点可以不用担心。如果要坚持用php做这个的话,我个人觉得只能加强些硬件性能了,否则可以换一种异步io的方式做做看(nodejs),但不见得一定有效,也不知道会不会有其他方面的问题。
这本身就不是个问题。我nginx设置的上传大小是100wGB。我认为就不应该设置这个限制。然后说回问题本身,有这么多用户你还愣用一个小水管!!?!?!这本身就不科学啊!!那腾讯网银新浪神马的岂不是都能一台服务器搞定所有事了= =

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
