如何开发api接口

[zhuyf333]

之前用webservice写接口比较多，也写过HttpClient访问别人提供的API接口，自己没有写过API服务端，网上搜索了一下，很少能说明的例证，自己尝试写了个测试，web.xml文件配置了映射，访问时却找不到访问路径，在这里请教一下，谁能给一个完整的可用例子，写出如同wish平台对外提供的API接口一样的服务，http://merchant.wish.com/documentation/api。另外再请教一下，使用这种接口转成json格式传输文件是否速度和时间响应比较慢

据我现在用的别人的接口，restful形式的比较流行，而之前用spring4的时候发现对restful接口的开发有专门的支持，具体没用过，楼主感兴趣的话可以看下

我感觉就像自己写页面发请求调用后台的action是一样的道理。给对方一个action的请求url，对方请求一下就调用了。如果是ajax调用的话要注意跨域。现在有很多open api，像豆瓣的新浪微博的等等，可以多参考下看看。

这样看你怎么实现了。 同样是 json，第三方工具选不好，也有可能很慢

两种错误，大同小异

[zhuyf333]

测试程序再次遇到问题，都是和SSL的验证相关，我代码中没有涉及SSL，但是客户端DefaultHttpClient.execute(Post)或httpClient.executeMethod(postMethod)的时候都报SSL的错误，不知道是tomcat服务器配置有问题，还是必须使用SSL验证，在之前与其他公司接口中我客户端并没有使用SSL验证，也没有报过错

报的啥子错误？

哪里需要开发，直接拿来用就行了，给你个地址，资源不要太多，http://www.ttsju.com/
