HttpClientUtil:
GET 设置超时时间：
public static String doGet(String url) {
String respContent = "";
try {
HttpClient client = new DefaultHttpClient();
client.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 1000);
HttpGet httpGet = new HttpGet(url);
HttpResponse resp = client.execute(httpGet);
if (resp.getStatusLine().getStatusCode() == 200) {
HttpEntity he = resp.getEntity();
respContent = EntityUtils.toString(he, "UTF-8");
} else {
respContent = "Http响应异常";
}
} catch (Exception e) {
LOGGER.error("HttpUtil get, err:", e);
}
return respContent;
}
GET:
public static String get(String urlNameString) {
String result = "";
CookieStore cookieStore = new BasicCookieStore();
CloseableHttpClient httpClient = HttpClients.custom()
.setDefaultCookieStore(cookieStore)
.build();
try {
HttpGet get = new HttpGet(urlNameString);
//这里发送get请求
BasicClientCookie cookie = new BasicClientCookie("token", "49ba41f0-862b-4c31-add8-b07066b777d9");
cookie.setDomain("xxx.com.cn");
cookie.setPath("/");
cookieStore.addCookie(cookie);
// 通过请求对象获取响应对象
HttpResponse response = httpClient.execute(get);
// 判断网络连接状态码是否正常(0--200都数正常)
result = EntityUtils.toString(response.getEntity(), "utf-8");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return result;
}
POST:
public static String post(String urlNameString, Integer id, Boolean bo) {
String result = "";
CookieStore cookieStore = new BasicCookieStore();
CloseableHttpClient httpClient = HttpClients.custom()
.setDefaultCookieStore(cookieStore)
.build();
try {
StringEntity entity = new StringEntity("{\"id\":\"" + id + "\",\"enable\":" + bo + "}", "utf-8");
//解决中文乱码问题
entity.setContentEncoding("UTF-8");
entity.setContentType("application/json");
HttpPost post = new HttpPost(urlNameString);
//这里发送get请求
post.setEntity(entity);
BasicClientCookie cookie = new BasicClientCookie("token", "f9ed047d-f708-4cda-b1bc-d6abccbde576");
cookie.setDomain("xxx.com.cn");
cookie.setPath("/");
cookieStore.addCookie(cookie);
// 通过请求对象获取响应对象
HttpResponse response = httpClient.execute(post);
// 判断网络连接状态码是否正常(0--200都数正常)
result = EntityUtils.toString(response.getEntity(), "utf-8");
} catch (Exception e) {
