请求的个性化配置

1. 请求头设置

//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});
