本文介绍了一种使用Java程序通过HTTP POST方法访问ABAP Netweaver服务器的方法。源代码示例展示了如何设置HTTP客户端，创建POST请求，以及如何处理响应。此示例包括了设置请求头、构造多部分实体以及解析服务器返回的数据。

使用Java程序通过http post访问ABAP Netweaver服务器

source code如下:

import java.io.FileNotFoundException;

import java.io.IOException;

import org.apache.commons.codec.binary.Base64;

import org.apache.http.HttpEntity;

import org.apache.http.HttpResponse;

import org.apache.http.client.ClientProtocolException;

import org.apache.http.client.HttpClient;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.entity.mime.HttpMultipartMode;

import org.apache.http.entity.mime.MultipartEntityBuilder;

import org.apache.http.impl.client.DefaultHttpClient;

import org.apache.http.util.EntityUtils;

@SuppressWarnings("deprecation")

public class MyHTTPPost

{

final private static String POST_PREFIX = <replace with your own application server url>;

private static String getRequestURL(String str)

{

String url = POST_PREFIX + str;

url = url + "&sid=" + Math.random();

return url;

}

private static void sendHTTPPostRequest(String str) throws FileNotFoundException

{

HttpClient httpclient = new DefaultHttpClient();

String raw = "WANGJER:Saptest1";

String encoded = Base64.encodeBase64String(raw.getBytes());

HttpPost httppost = new HttpPost(getRequestURL(str));

MultipartEntityBuilder builder = MultipartEntityBuilder.create();

builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

builder.addTextBody("firstName", "Jerry");

builder.addTextBody("lastName", "Wang");

try {

httppost.addHeader("Content-Type","multipart/form-data; boundary=assdsfdffafasf");

httppost.addHeader("User-Agent","Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)");

httppost.addHeader("Authorization", "Basic " + encoded);

HttpResponse httpresponse = httpclient.execute(httppost);

HttpEntity resEntity = httpresponse.getEntity();

String response = EntityUtils.toString(resEntity);

System.out.println(response);

}

catch (IOException e)

{

System.out.println(e.getLocalizedMessage());

e.printStackTrace();

System.out.println("error!");

}

public static void main(String[] args) throws ClientProtocolException, IOException

{

sendHTTPPostRequest("a");

}

运行结果:
application server会解析出Java program传入的http 请求中的"a", 然后从DB table scarr 中查找对应的记录，返回给Java side:
