原标题:How to make an app submit info into a webform

I was trying to write an android app to help people do easier searches on multiple websites like craiglist, ebay ..etc I am not sure where really to start from, or the name of the technology I would be using. To make it more accurate question, these websites are all forms based that you either post stuffs or retreive stuffs through searching. How can I make my android app actually in which it will ask the user for a item name (that part I know) and then send item name to say craiglist so it gets the results back?

I was thinking of copying the url that is displayed on my broswer when I click search on any of the website and using the same link with string manipulation to include whats needed. Is this correct? Any other ideas are I know? I am kinda all over the place, but I need a starting point.

有些网站可能会暴露 公众API 与您连接, 但这个网站是特定的。

不暴露此系统的网站可以被“ 剪切”, 这意味着您再次使用字符串操纵( 如您提到的 ) 来分析您之后的数据 。

这两种方式都需要关于如何进行HTTP操作的基本知识,有几种方法可以做到这一点,但这是使用HttpurLoncomnction 类的最容易的方式,如网上的各种教程所描述的那样。

Googling的“机器人http Get POST 教程”应该指向正确的方式,
