Java 发送http请求上传文件功能实例

Java 发送发送http请求上传文件功能实例请求上传文件功能实例

本文通过实例代码给大家介绍了Java 发送http请求上传文件功能，需要的朋友参考下吧

废话不多说了，直接给大家贴代码了，具体代码如下所示：

package wxapi.WxHelper;

import java.io.BufferedReader;

import java.io.DataInputStream;

import java.io.DataOutputStream;

import java.io.File;

import java.net.URLConnection;

import java.util.Date;

import java.util.Map;

import java.util.Map.Entry;

public class HttpRequestUtil {

/**

* 发送get请求

*

* @param requestUrl

* 请求url

public static String sendGet(String requestUrl, Map<String, String> requestHeader, String responseEncoding) {

String result = "";

BufferedReader reader = null;

try {

if (requestUrl == null || requestUrl.isEmpty()) {

return result;

}

URL realUrl = new URL(requestUrl);

URLConnection connection = realUrl.openConnection();

connection.setRequestProperty("accept", "text/html, application/xhtml+xml, image/jxr, */*");

connection.connect();

if (responseEncoding == null || responseEncoding.isEmpty()) {

responseEncoding = "UTF-8";

}

reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), responseEncoding));

String line;

while ((line = reader.readLine()) != null) {

result += line;

}

} catch (Exception e) {

}

} catch (Exception e) {

e.printStackTrace();

}

}

return result;

}

/**

* 发送post请求

*

* @param files

* 上传文件

* @param requestEncoding

* 请求编码

* @param responseEncoding

* 响应编码

* @return 页面响应html

*/

public static String sendPost(String requestUrl, Map<String, String> requestHeader, Map<String, String> formTexts, Map<String, String> files, String requestEncoding, String responseEncoding) {

OutputStream out = null;

URL realUrl = new URL(requestUrl);

HttpURLConnection connection = (HttpURLConnection) realUrl.openConnection();

connection.setRequestProperty("accept", "text/html, application/xhtml+xml, image/jxr, */*");

connection.setRequestProperty("user-agent", "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:53.0) Gecko/20100101 Firefox/53.0");
