内网服务器如何调用第三方的API?
我的服务器架构是:
1.一台反向代理,能访问外网 LINUX NGINX;
2.两台应用服务器跑PHP程序 LINUX NGINX PHP;
3.一台DB、一台CACHE
现在开放平台很多,我们项目采用了不少第三方的API如(七牛、微信、支付宝等),问题是这些API都需要向外网请求的。我的代码都跑在内网里面,调用不到API。
我现在的解决办法就是把需要调外网的都另外写一份代码放到外网服务器上跑,但是这样问题很多,一些公共的类什么的也要维护两份。
我想问问能否在外网机上做代理,给内网机通过代理访问外网的方式来调用开放平台的接口呢?

能访问外网的服务器上搭建一个http透明代理只允许内网访问,内网CURL指定proxy就可以了。
你跑PHP的机器是怎么做到不能上网的?
可以使用SSH的端口转发功能实现。
假定A是本地内网主机,B是远程提供第三方服务的主机,这两台主机之间无法连通。但是,现在还有一台C,可以同时连通前面两台主机。因此,很自然的想法就是,通过C,将A连上B。
在A上执行如下命令:
1 |
|
参数的意思是“本地端口:目标主机:目标主机端口"。这条命令的意思就是指定SSH绑定本地端口3002,然后指定C将所有的数据,转发到目标主机B的3001端口(你也可以指定其它端口)。
这样一来,我们只要连接A的3002端口,就等于连上了B的3001端口。这样我们还可以让那些不加密的网络连接,全部改走SSH连接,从而提高安全性。

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.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

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 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.

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 has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.
