java - 将查询参数添加到 GetMethod(使用 Java commons-httpclient)？

Question

我关注了this other SO question为 URL 设置参数但出现错误:

The method setQueryString(String) in the type HttpMethodBase is not applicable for the arguments (NameValuePair[])

和

Cannot instantiate the type NameValuePair.

我无法理解实际问题。有人可以帮我解决这个问题吗？

我从上面的问题中使用的代码

GetMethod method = new GetMethod("example.com/page";); 
method.setQueryString(new NameValuePair[] { 
    new NameValuePair("key", "value") 
});

在 HttpClient 4.x 中，不再有 GetMethod。取而代之的是 HttpGet。引用 tutorial 中的示例:

url中的查询参数:

HttpGet httpget = new HttpGet(
 "http://www.google.com/search?hl=en&q=httpclient&btnG=Google+Search&aq=f&oq=");

以编程方式创建查询字符串:

URIBuilder builder = new URIBuilder();
builder.setScheme("http").setHost("www.google.com").setPath("/search")
    .setParameter("q", "httpclient")
    .setParameter("btnG", "Google Search")
    .setParameter("aq", "f")
    .setParameter("oq", "");
URI uri = builder.build();
HttpGet httpget = new HttpGet(uri);
System.out.println(httpget.getURI());
