# HttpUtils工具类

**HttpUtils工具类进行url链接转发**

```java
package com.mmit.common;

import java.io.IOException;

import org.apache.http.HttpEntity;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class HttpUtils {
	/**
	 * 以字符串形式返回url内容
	 */
	public static String getHttpString(String url){
		String result = "";
		CloseableHttpClient httpclient = HttpClients.createDefault();
		HttpGet httpGet = new HttpGet(url);
		RequestConfig requestConfig = RequestConfig.custom()
		        .setConnectTimeout(50000).setConnectionRequestTimeout(10000)
		        .setSocketTimeout(50000).build();
		httpGet.setConfig(requestConfig);		
		
		CloseableHttpResponse response = null;
		try {
			response = httpclient.execute(httpGet);
		    HttpEntity entity = response.getEntity();		    
		    result = EntityUtils.toString(entity);

} catch (ClientProtocolException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		} finally {
		    try {
		    	if(response != null)
		    		response.close();
		    	httpclient.close();
			} catch (IOException e) {
				e.printStackTrace();
			}
		    
		}
		return result;	
	}
}
```

通过调用HttpUtils的getHttpString()方法，传递需要跳转的url;

```
String url =  "https://lilinchao.com/";
String urlStr = HttpUtils.getHttpString(url);
```
