通过HttpClient4.5.3发送http get请求

1、添加jar或者maven依赖

或者添加maven依赖

<dependency>

<groupId>org.apache.httpcomponents</groupId>

<artifactId>httpclient</artifactId>

<version>4.5.3</version>

</dependency>

该maven对应如下jar

2、代码样例如下

代码如下：

/**

* httpGet请求

*/

public static void httpGet() {

final String url = LOCATION_URL; //此处为需要访问的url链接地址

CloseableHttpClient httpClient = HttpClients.createDefault();

RequestConfig requestConfig = RequestConfig.custom()

.setConnectTimeout(5000) //设置连接超时时间

.setConnectionRequestTimeout(5000) // 设置请求超时时间

.setSocketTimeout(5000)

.setRedirectsEnabled(true)//默认允许自动重定向

.build();

try {

HttpGet httpGet = new HttpGet(url);

httpGet.setConfig(requestConfig);

CloseableHttpResponse response = httpClient.execute(httpGet);

try {

int statusCode = response.getStatusLine().getStatusCode();

System.out.println("HTTP Status Code:" + statusCode);

if (statusCode != HttpStatus.SC_OK) {

System.out.println("HTTP请求未成功！HTTP Status Code:" + response.getStatusLine());

}

HttpEntity httpEntity = response.getEntity();

if (httpEntity != null) {

String reponseContent = EntityUtils.toString(httpEntity,"UTF-8");

EntityUtils.consume(httpEntity);//释放资源

System.out.println("响应内容：" + reponseContent);

}

} catch (Exception e) {

e.printStackTrace();

} finally {

response.close();

}

} catch (Exception e) {

e.printStackTrace();

}

finally {

try {

httpClient.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}
