学习记录---URIBuilder

常用方法URIBuilder setParameters(final List nvps)URIBuilder addParameters(final List nvps)URIBuilder setParameters(final NameValuePair… nvps)上面这三个方法中我觉得俩set其实是一样的URIBuilder addParameter(final String param

构造函数
URIBuilder()
URIBuilder(final String string) 内部会创建URI对象
URIBuilder(final URI uri)
非空的两个构造实际内部都调用了digestURI（uri）将URI对象解析并赋值给类的属性
类属性

    String url = "http://www.google.com/search?hl=en&q=httpclient&btnG=Google+Search&aq=f&oq=";
    URIBuilder uriBuilder = new URIBuilder(url);
    System.out.println(uriBuilder.getScheme());
    System.out.println(uriBuilder.getUserInfo());
    System.out.println(uriBuilder.getHost());
    System.out.println(uriBuilder.getPort());
    System.out.println(uriBuilder.getPath());
    System.out.println(uriBuilder.getQueryParams());
    System.out.println(uriBuilder.getFragment());
    System.out.println(uriBuilder.getCharset());

    输出如下所示：
    scheme：http
    userinfo：null
    host：www.google.com
    prot：-1  端口默认是80，当显示指定端口时，此处便能取到值
    path：/search
    queryParams：[hl=en, q=httpclient, btnG=Google Search, aq=f, oq=]
    fragment：null
    charset：null
    某些属性含义未知手动设置一次
    String url = "http://info.sporttery.cn/football/info/fb_match_hhad.php?m=102909";
    URIBuilder uriBuilder = new URIBuilder(url);
    uriBuilder.setFragment("111");
    uriBuilder.setUserInfo("222", "333");
    uriBuilder.setCharset(new GBK());
    System.out.println(uriBuilder.build());
    System.out.println(uriBuilder.getScheme());
    System.out.println(uriBuilder.getUserInfo());
    System.out.println(uriBuilder.getHost());
    System.out.println(uriBuilder.getPath());
    System.out.println(uriBuilder.getQueryParams());
    System.out.println(uriBuilder.getFragment());
    System.out.println(uriBuilder.getCharset());
    输出如下：
    http://222:333@info.sporttery.cn/football/info/fb_match_hhad.php?m=102909#111
    scheme：http
    userInfo：222:333   没见过这东西-。-
    host：info.sporttery.cn
    path：/football/info/fb_match_hhad.php
    queryParams：[m=102909]
    fragment：111   路由
    charset：GBK

常用方法
URIBuilder setParameters(final List nvps)
URIBuilder addParameters(final List nvps)
URIBuilder setParameters(final NameValuePair… nvps)
上面这三个方法中我觉得俩set其实是一样的

    String url = "http://info.sporttery.cn/football/info/fb_match_hhad.php?m=102909";
    URIBuilder uriBuilder = new URIBuilder(url);
    ArrayList<NameValuePair> objects = new ArrayList<>();
    ArrayList<NameValuePair> objects1 = new ArrayList<>();
    NameValuePair m = new BasicNameValuePair("m", "1");
    objects.add(m);
    NameValuePair m1 = new BasicNameValuePair("m", "8");
    objects1.add(m1);
    uriBuilder.setParameters(objects);
    uriBuilder.addParameters(objects1);
    System.out.println(uriBuilder.build());
    输出：http://info.sporttery.cn/football/info/fb_match_hhad.php?m=1&m=8
    得出结论：set会覆盖原来的同名参数而add不会

URIBuilder addParameter(final String param, final String value)
URIBuilder setParameter(final String param, final String value)

    String url = "http://info.sporttery.cn/football/info/fb_match_hhad.php?m=102909";
    URIBuilder uriBuilder = new URIBuilder(url);
    uriBuilder.setParameter("m", "2");
    uriBuilder.addParameter("m" ,"5");
    System.out.println(uriBuilder.build());
    输出：http://info.sporttery.cn/football/info/fb_match_hhad.php?m=2&m=5
    得出结论：set会覆盖原来的同名参数而add不会

URIBuilder clearParameters()

    String url = "http://info.sporttery.cn/football/info/fb_match_hhad.php?m=102909";
    URIBuilder uriBuilder = new URIBuilder(url);
    uriBuilder.clearParameters();
    System.out.println(uriBuilder.build());
    输出：http://info.sporttery.cn/football/info/fb_match_hhad.php
    就是清除所有参数
