一、httpClient模拟客户端
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
public class GpoHttpClientServiceImpl {
@DataProvider(name = "datapro")
public Iterator<Object[]> datapro() {
return new ExcelDataProvider("hospitalInv", "invokeGpoHttpServer");
}
@Test(dataProvider = "datapro")
public void invokeGpoHttpServer(Map<String, String> data) throws Exception {
// 创建http post请求
HttpPost httppost = new HttpPost(data.get("httpUrl"));
// 将请求的xml格式的字符串进行压缩
String zipReqxml = ZipUtil.zipBase64String(data.get("reqXml"));
// 将请求的xml业务数据与接口密钥一起使用MD5加密,指定字符集为UTF-8
String sign = MD5Util.sign(data.get("reqXml"), data.get("mscpKey"), "utf-8");
// 将服务端所需要的参数以BasicNameValuePair键值对的方式进行封装,并添加到一个NameValuePair类型的list中,作为传送的容器,list中的每个元素都是一个键值对
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("mscpCode", data.get("mscpCode")));
params.add(new BasicNameValuePair("sign", sign));
params.add(new BasicNameValuePair("reqXml", zipReqxml));
// 设置http请求实体,http接口服务端接收数据的格式为NameValuePair类型的list实体
httppost.setEntity(new UrlEncodedFormEntity(params, "utf-8"));
// 创建http客户端
CloseableHttpClient httpclient = HttpClients.createDefault();
// 发送http post请求
HttpResponse response = httpclient.execute(httppost);
// 获取服务端返回的httpCode
int httpCode = response.getStatusLine().getStatusCode();
// 将服务端返回的结果实体转换成字符串
String result = EntityUtils.toString(response.getEntity());
System.out.println("HttpCode:" + httpCode + " 服务器返回结果:" + result);
}
}
二、MD5接口数据加密
import java.io.UnsupportedEncodingException;
import java.security.SignatureException;
import org.apache.commons.codec.digest.DigestUtils;
public class MD5Util {
/**
* 签名字符串
*
* @param text
* 需要签名的字符串
* @param key
* 密钥
* @param input_charset
* 编码格式
* @return 签名结果
*/
public static String sign(String text, String key, String input_charset) {
text = text + key;
return DigestUtils.md5Hex(getContentBytes(text, input_charset));
}
/**
* @param content
* @param charset
* @return
* @throws SignatureException
* @throws UnsupportedEncodingException
*/
private static byte[] getContentBytes(String content, String charset) {
if (charset == null || "".equals(charset)) {
return content.getBytes();
}
try {
return content.getBytes(charset);
} catch (UnsupportedEncodingException e) {
throw new RuntimeException("MD5签名过程中出现错误,指定的编码集不对,您目前指定的编码集是:" + charset);
}
}
}
三、对传输的数据进行压缩
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
import java.util.zip.ZipOutputStream;
import org.apache.commons.codec.binary.Base64;
public class ZipUtil {
/**
* 使用zip进行压缩
*
* @param str
* 压缩前的文本
* @return 返回压缩后的文本
*/
public static final String zipBase64String(String str) {
if (str == null)
return null;
byte[] compressed;
ByteArrayOutputStream out = null;
ZipOutputStream zout = null;
String compressedStr = null;
try {
out = new ByteArrayOutputStream();
zout = new ZipOutputStream(out);
zout.putNextEntry(new ZipEntry("zip"));
zout.write(str.getBytes("utf-8"));
zout.closeEntry();
compressed = out.toByteArray();
compressedStr = Base64.encodeBase64String(compressed);
} catch (IOException e) {
e.printStackTrace();
compressed = null;
} finally {
if (zout != null) {
try {
zout.close();
} catch (IOException e) {
}
}
if (out != null) {
try {
out.close();
} catch (IOException e) {
}
}
}
return compressedStr;
}
/**

*
* @param compressed
* Base64转码的压缩文本
* @return 解压后的字符串
*/
public static String unzipBase642String(String base64CompressedStr) {

byte[] compressed = Base64.decodeBase64(base64CompressedStr);
in = new ByteArrayInputStream(compressed);
ginzip = new ZipInputStream(in);
ginzip.getNextEntry();
byte[] buffer = new byte[1024];
int offset = -1;
while ((offset = ginzip.read(buffer)) != -1) {
out.write(buffer, 0, offset);
}
decompressed = out.toString("utf-8");
} catch (IOException e) {
e.printStackTrace();
} finally {
if (out != null) {
try {
out.close();
} catch (IOException e) {
}
}
if (ginzip != null) {
try {
ginzip.close();
} catch (IOException e) {
}
}
if (in != null) {
try {
in.close();
} catch (IOException e) {
