什么是API接口？主要作用是什么？

API英文全称为：Application Programming Interface，中文意思是应用程序编程接口，它是一些预先定义的函数，目的是提供应用程序与开发人员基于某软件或硬件得以访问一组例程的能力。

主要作用：

API之主要目的是提供应用程序与开发人员以访问一组例程的能力，而又无需访问源码，或理解内部工作机制的细节。提供API所定义的功能的软件称作此API的实现。API是一种接口，故而是一种抽象。

扩展资料：

API数据接口的好处：

1、良好的接口设计可以降低系统各部分的相互依赖，提高组成单元的内聚性，降低组成单元间的耦合程度，从而提高系统的维护性和扩展性。应用程序接口是一组数量上千、极其复杂的函数和副程序，可让程序员做很多任务。

2、98数据致力于打造高质量API，除了自身的数据外，来自合作伙伴的各类API数据也是经过慎重的筛选，接口的质量和稳定性比较好，适合对接口质量和稳定性有较高要求的开发者。API数据接口作为众多开发人员进行开发工作最有效的助手，以后也会发挥着更大的作用，所以找到合适的接口才是最为重要的。

有什么免费的股票数据web api

免费的很多，例如新浪的web api。但这种会被对方封IP。
其实免费的，最好是使用股票软件中自带的接口。例如通达信、同花顺、大智慧的公式系统。这些软件里面可编写公式，通过这些公式，就可按自己要求得到对应的股票数据了。
如果是机构，有专业的这种API接口的提供。例如微盛的金融实时行情API接口，但这种需要软件人员才搞得懂，一般人没法使用。

国内有哪些城市较完整可以免费使用的天气 API 接口

因微信公共号提供城市天气预报服务，发现网山天气预报接口和环境数据接口方面资料比较乱，而且有不少内容已经失效，下面内容由过程日志整理形成，希望可用得上。
一 天气预报
国内的天气预报数据，主要是国家气象局和国外两个来源（指数据来源）。
国外方面主要是雅虎（XML格式，谷歌已经停掉了自家的天气API）；
国内数据由国家气象局提供（JSON格式）。
在知乎看到过一篇专业人士评论，雅虎可以提供全球范围的且非常精细的天气数据（小时级更新），但主要是通过计算机自动生成。而国家气象局则是各地经验丰富的专家人士结合计算机综合分析得出，在准确性上更胜一筹。我就这样信了！
国家气象局接口资源及用法
气象局的天气预报主页：移动版普通版 ,仔细挖掘这两个地址可以发现很多好东西哦。
特点：接口多，来自weather.com.cn和mobile.weather.com.cn都有，次数不限制，服务稳定，功能全面，优先推荐。
1. 实时天气接口
有多个接口，好像差别不大：
实时天气1：http://www.weather.com.cn/data/sk/101190408.html
实时天气2：http://www.weather.com.cn/data/cityinfo/101190408.html
实时天气3（带时间戳）：http://mobile.weather.com.cn/data/sk/101010100.html?_=1381891661455
2. 一周天气预报接口
7天预报数据 URL： http://mobile.weather.com.cn/data/forecast/101010100.html?_=1381891660081
该接口来源气象局移动版网站，目测数据最为精确，详细接口格式如下：

免费天气api接口怎么应用到安卓源代码里

我今天也收到客户抱怨了，上中国天气网查看到了一个公告，看样子是API要变的节奏： 1234为更好地为用户提供气象数据服务，新版气象数据开放平台于2014年11月17日正式上线。新用户可在线注册帐户，详细填写用户资料，按照申请流程提示申请数据接口，审核通过后，系统会自动分发密钥。新用户API数据接口通过审核后一年有效，逾期未续约将自动失效，API数据产品类型详见开放平台产品中心。 已申请并开通接口的老用户可继续使用原有API接口，原有API接口自今日起一年内有效，于2015年11月16日自动关闭，如有使用需要，建议老用户在接口关闭之前申请新API接口，申请流程及具体说明参见新用户申请。 请广大开发者相互转告，我们一直努力，为大家提供不断优化的气象数据服务 关于免费api数据接口和免费公开api接口大全的介绍到此就结束了，不知道你从中找到你需要的信息了吗 ？如果你还想了解更多这方面的信息，记得收藏关注本站。 免费api数据接口的介绍就聊到这里吧，感谢你花时间阅读本站内容，更多关于免费公开api接口大全、免费api数据接口的信息别忘了在本站进行查找喔。
