HomeBackend DevelopmentPHP Tutorialjavascript - 了解一个网站遇到一个js文件里使用api调用的问题?

案例地址 http://www.cndf.com/order/price.php

首先我的目的是想要知道 能通过几个选项自动计算出价格的方法。 通过查看html,了解到是

<code><script type="text/javascript" src="./js/ajax.js"></script>
</code>

这个js文件的作用,我测试过,源网站离线是无法计算出结果的,必须是联网状态下。将这个网页下载到本地,对ajax.js使用原网站的绝对路径,然后也无法计算出结果。然后查看该js代码头文件有个api

<code>ESSAYBAR={
    'api':'./api.php',
    'order':null
};
</code>

将js离线下载下来对api.php使用绝对路径依然无法计算。 求诸位大神,这是什么原理,有没有解决方法。

api.php 是服务端脚本,会在服务端执行。正常情况下你下载不了的。

又没有CORS,ajax不能跨域,你下载到本地js怎么会有用?
在服务器端做请求吧

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
