推荐另外一个工具：
OKHttpUtil 功能
- 根据URL自动判断是请求HTTP还是HTTPS，不需要单独写多余的代码。
- 默认情况下Cookie自动记录，比如可以实现模拟登录，即第一次访问登录URL后后续请求就是登录状态。
- 自动识别304跳转并二次请求
- 支持代理配置
- 支持referer配置
- 支持User-Agent配置
- 自动识别并解压Gzip格式返回内容
- 支持springboot 配置文件
- 极简的封装调用

Get
Response response = HttpUtil.get(https://github.com/search, Pair.of(q, okhttp)); System.out.println(response = + response);
一行代码即可搞定，当然Post请求也很简单： # JSON 格式的body Response post = HttpUtil.post(https://oapi.dingtalk.com/robot/send?access_token=27f5954ab60ea8b2e431ae9101b1289c138e85aa6eb6e3940c35ee13ff8b6335, {\msgtype\: \text\,\text\: {\content\:\【反馈提醒】我就是我, 是不一样的烟火\}}); System.out.println(post = + post); # form 请求 Map<String, Object> formParams = new HashMap<>(16); formParams.put(username, admin); formParams.put(password, admin123); Response response = HttpUtil.postForm(http://192.168.1.13:9100/auth/login, formParams ); System.out.println(response = + response); 返回格式为JSON的 可以使用 HttpJsonUtil 自动返回JsonObject JSONObject object=HttpJsonUtil.get(https://github.com/search, Pair.of(q,http), Pair.of(username,agonie201218)); System.out.println(object = +object); 文件上传 File file=new File(C:\\Users\\andanyang\\Downloads\\Sql.txt); Map<String, Object> formParams=new HashMap<>(); formParams.put(key,test); formParams.put(file,file); formParams.put(token,WXyUseb-D4sCum-EvTIDYL-mEehwDtrSBg-Zca7t:qgOcR2gUoKmxt-VnsNb657Oatzo=:eyJzY29wZSI6InpoYW56aGkiLCJkZWFkbGluZSI6MTY2NTMwNzUxNH0=); Response response=HttpUtil.upload(https://upload.qiniup.com/,formParams); System.out.println(response); 下载文件 HttpUtil.down(https://gitee.com/admin4j/common-http,path/); HttpRequest 链式请求 # get Response response=HttpRequest.get(https://search.gitee.com/?skin=rec&type=repository) .queryMap(q,admin4j) .header(HttpHeaderKey.USER_AGENT,admin4j) .execute(); System.out.println(response = +response); # post form Response response=HttpRequest.get(http://192.168.1.13:9100/auth/login) .queryMap(q,admin4j) .header(HttpHeaderKey.USER_AGENT,admin4j) .form(username,admin) .form(password,admin123) .execute(); System.out.println(response = +response);

一、PostMethod一般请求 /** * POST方式 * @return * @throws Exception */ public static String PostMethodTest() throws Exception{ System.out.println("开始"); HttpClient client = new HttpClient(); PostMethod method = new PostMethod(URI); try{ method.addRequestHeader(new Header("Content-Type", "application/x-www-form-urlencoded;charset=utf-8") ); // method.addRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8"); method.addParameter(new NameValuePair("appid", "XXXX") ); method.addParameter(new NameValuePair("appkey", "XXXX") ); // method.addParameter("appid", "XXXX"); // method.addParameter("appkey", "XXXX"); int result = client.executeMethod(method); if (result == HttpStatus.SC_OK) { InputStream in = method.getResponseBodyAsStream(); ByteArrayOutputStream baos = new ByteArrayOutputStream(); byte[] buffer = new byte[1024]; int len = 0; while ((len = in.read(buffer)) != -1) { baos.write(buffer, 0, len); } return URLDecoder.decode(baos.toString(), "UTF-8"); } else { throw new Exception("HTTP ERROR Status: " + method.getStatusCode() + ":" + method.getStatusText()); } }finally { method.releaseConnection(); } } 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 二、PostMethod带文件方式 /** * POST方式 传带文件的调用 * @return * @throws Exception */ public static String PostMethodFileTest() throws Exception{ System.out.println("开始"); HttpClient client = new HttpClient(); PostMethod method = new PostMethod(URI); try{ FilePart filePart = new FilePart("file",new File("D:\\8\\5972-41-2017-06-07-1440-16406.wav"));//文件参数 StringPart questionId = new StringPart("questionId","10001");//普通参数 StringPart userId = new StringPart("userId","765709");//普通参数 StringPart homeworkId = new StringPart("homeworkId","950");//普通参数 Part[] parts ={filePart,questionId,userId,homeworkId}; MultipartRequestEntity mre=new MultipartRequestEntity(parts ,method.getParams()); //封装了普通字段和文件字段 method.setRequestEntity(mre ); int result = client.executeMethod(method); if (result == HttpStatus.SC_OK) { InputStream in = method.getResponseBodyAsStream(); ByteArrayOutputStream baos = new ByteArrayOutputStream(); byte[] buffer = new byte[1024]; int len = 0; while ((len = in.read(buffer)) != -1) { baos.write(buffer, 0, len); } return URLDecoder.decode(baos.toString(), "UTF-8"); } else { throw new Exception("HTTP ERROR Status: " + method.getStatusCode() + ":" + method.getStatusText()); } }finally { method.releaseConnection(); } }
解析response:
import org.json.JSONObject;
import org.json.XML;
jsonObject = XML.toJSONObject(response);
