org.apache.http.client.HttpClient 怎么发送一段xml到服务器啊
注意: 这里的httpclient不是common包下的 是org.apache.http.client.HttpClient 1 org.apache.http.client.HttpClient 有没有注入setQueryString("")这样的方法呢. 2 或者有没其他方法来发送一段xml文件 3 org.apache.http.client.HttpClient 可不可以获取httprequest 如果可以获取又应该怎么获取呢 [b]问题补充:[/b] 谢谢 yuankai 只是你提供的代码 其实是基于common包下的httpclient 不是我所要的。谢谢。 [b]问题补充:[/b] common包下提交请求的两个对象:PostMethod GetMethod 我想要的提交请求的两个对象的是 HttpPost HttpGet

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
