请求的个性化配置

//创建 请求
RequestBuilder requestBuilder = RequestBuilder.get().setUri("https://www.baidu.com/");
HttpUriRequest httpGet = requestBuilder.build();
/**
 * 设置请求头, eg: Accept: text/plain
 */
//单个设置
httpGet.setHeader(HttpHeaders.ACCEPT, ContentType.TEXT_PLAIN.getMimeType());
//多个设置
Header acceptHeader = new BasicHeader(HttpHeaders.ACCEPT, ContentType.TEXT_PLAIN.getMimeType());
Header contentTypeHeader = new BasicHeader(HttpHeaders.CONTENT_TYPE, ContentType.APPLICATION_JSON.getMimeType());
httpGet.setHeaders(new Header[]{acceptHeader, contentTypeHeader});

//创建 请求
RequestBuilder requestBuilder = RequestBuilder.get().setUri("https://www.baidu.com/");
/**
 * GET请求的参数都是拼装在URL地址后方
 *      addParameter()
 *      addParameters() ---  List<NameValuePair> --- BasicNameValuePair
 */
//单个单个添加
requestBuilder.addParameter("username", "JiMu");
requestBuilder.addParameter("password", "123456");

//设置参数数组
List<NameValuePair> paramList = new ArrayList<NameValuePair>();
BasicNameValuePair para1 = new BasicNameValuePair("username", "JiMu");
paramList.add(para1);
BasicNameValuePair para2 = new BasicNameValuePair("password", "123456");
paramList.add(para2);
requestBuilder.addParameters(paramList.toArray(new NameValuePair[paramList.size()]));

HttpUriRequest httpGet = requestBuilder.build();
//输出请求行：https://www.baidu.com/?username=JiMu&password=123456&username=JiMu&password=123456
System.out.println(httpGet.getRequestLine().getUri());
