问题描述

我需要在我的C #Windows窗体应用程序中计算某些函数的积分，函数可以是任何例如X ^ 2或2的激进。我已经决定将该函数提供给积分计算器网站（ http://www.integral-calculator.com [ ^ ]或 http://integrals.wolfram.com/index.jsp [ ^ ]或 http://www.wolframalpha.com/input/?i=integrate+x%5E2 [ ^ ]）并阅读他们的回答。

推荐答案

很好的问题，但问题是该网站没有API。您通常使用HTTP API发送请求并获取请求的响应。除此之外，由于CORS，您更有可能将请求的状态取消; 跨域资源共享。



但是有一件事你可以做，在网站的最后，作者分享了他的电子邮件地址。您可以联系他询问方法，他可能会为您（以及其他具有相同意见和需求的开发人员）创建API。然后你可以用一些表达式向网站发送请求并获得结果。

Good question, but the thing is that there is no API for the website. You usually use an HTTP API to send requests and get responses for the request. Apart from this, you are more likely to get your request's status CANCELLED because of CORS; cross-origion resource sharing.

There is however one thing that you can do, at the end of the website author has shared his email address. You can contact him to ask for a way, he might create an API for you (and other developers with same opinion and need). Then you can send requests to the website with some expression and get the results.
