Apache中怎么實現(xiàn)一個httpclient封裝類,很多新手對此不是很清楚,為了幫助大家解決這個難題,下面小編將為大家詳細講解,有這方面需求的人可以來學習下,希望你能有所收獲。
在廣陽等地區(qū),都構(gòu)建了全面的區(qū)域性戰(zhàn)略布局,加強發(fā)展的系統(tǒng)性、市場前瞻性、產(chǎn)品創(chuàng)新能力,以專注、極致的服務(wù)理念,為客戶提供做網(wǎng)站、成都做網(wǎng)站 網(wǎng)站設(shè)計制作按需搭建網(wǎng)站,公司網(wǎng)站建設(shè),企業(yè)網(wǎng)站建設(shè),品牌網(wǎng)站設(shè)計,網(wǎng)絡(luò)營銷推廣,成都外貿(mào)網(wǎng)站制作,廣陽網(wǎng)站建設(shè)費用合理。
基于apache httpcomponents組件,首先依賴jar包
org.apache.httpcomponents httpclient 4.5.13 org.apache.httpcomponents httpmime 4.5.13
先來看使用方法:
/** * @author tanghc */ public class HttpTest { /** * 普通get請求 * @throws IOException */ @Test public void get() throws IOException { String s = HttpHelper.get("http://localhost:8089/http/get") // 添加請求參數(shù) .parameter("id", "1") .parameter("name", "jim") .execute() .asString(); System.out.println(s); } /** * post提交表單 * @throws IOException */ @Test public void postForm() throws IOException { Mapform = new HashMap<>(); form.put("id", 1); form.put("name", "tom"); String s = HttpHelper.postForm("http://localhost:8089/http/postForm", form) .execute() .asString(); System.out.println(s); } /** * post提交表單,并上傳文件。multipart * @throws IOException */ @Test public void postFormFile() throws IOException { Map form = new HashMap<>(); HttpHelper.UploadFile file = new HttpHelper.UploadFile("file", "a.txt", "hello world".getBytes()); form.put("id", 1); form.put("name", "tom"); String s = HttpHelper.postForm("http://localhost:8089/http/postFormFile", form, file) .execute() .asString(); System.out.println(s); } /** * post提交json * @throws IOException */ @Test public void postJson() throws IOException { Map form = new HashMap<>(); form.put("id", 1); form.put("name", "tom"); String json = JSON.toJSONString(form); String s = HttpHelper.postJson("http://localhost:8089/http/postJson", json) .execute() .asString(); System.out.println(s); } /** * 設(shè)置header * @throws IOException */ @Test public void setHeader() throws IOException { String s = HttpHelper.get("http://localhost:8089/http/header") // 設(shè)置單個header .header("token", "xxx") .execute() .asString(); System.out.println(s); Map headers = new HashMap<>(); headers.put("token", "bbbb"); String s2 = HttpHelper.get("http://localhost:8089/http/header") // 設(shè)置全部header .headers(headers) .execute() .asString(); System.out.println(s2); } /** * 返回流 * @throws IOException */ @Test public void getStream() throws IOException { InputStream inputStream = HttpHelper.get("http://localhost:8089/http/stream") .execute() .asStream(); String s = IOUtils.toString(inputStream); System.out.println(s); } /** * 獲取http狀態(tài) * @throws IOException */ @Test public void getStatus() throws IOException { HttpHelper.ResponseResult responseResult = HttpHelper.get("http://localhost:8089/http/get") .parameter("id", "1") .parameter("name", "jim") .execute(); int status = responseResult.getStatus(); if (status == HttpStatus.SC_OK) { System.out.println(responseResult.asString()); } } /** * 獲取響應(yīng)頭 * @throws IOException */ @Test public void getHeaders() throws IOException { Map form = new HashMap<>(); form.put("id", 1); form.put("name", "tom"); String json = JSON.toJSONString(form); HttpHelper.ResponseResult responseResult = HttpHelper.postJson("http://localhost:8089/http/responseHeader", json) .execute(); Map headers = responseResult.getHeaders(); System.out.println(headers.get("code")); System.out.println(headers.get("token")); System.out.println(responseResult.asString()); } /** * 獲取HttpResponse對象 * @throws IOException */ @Test public void getResponse() throws IOException { HttpHelper.ResponseResult responseResult = HttpHelper.get("http://localhost:8089/http/get") .parameter("id", "1") .parameter("name", "jim") .execute(); HttpResponse response = responseResult.getResponse(); Locale locale = response.getLocale(); System.out.println(locale); } /** * 自定義 * @throws IOException */ @Test public void custom() throws IOException { String s = HttpHelper.create() .url("http://localhost:8089/http/get") .method("get") .parameter("id", "1") .parameter("name", "jim") .header("token", "xx") .execute() .asString(); System.out.println(s); String json = "{ \"name\": \"Jim\" }"; String s2 = HttpHelper.create() .url("http://localhost:8089/http/postJson") .method("POST") .header("token", "xx") .entity(new StringEntity(json, ContentType.APPLICATION_JSON)) .execute() .asString(); System.out.println(s2); } }
