http接口开发及调用

一般用http的post，尽量不用get；

开发中一般都使用org.apache.http的jar包，比较成熟，方便，易用；当然了，直接用java提供的也行

package com.XXXX.XXXX.service;

import java.io.File;
import java.io.IOException;
import java.nio.charset.Charset;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.entity.ContentType;
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.HttpClientBuilder;
import org.apache.http.protocol.HTTP;
import org.apache.http.util.EntityUtils;

/*
* Http接口 post
* 接收下属客户端上传样本,保存样本文件
* apache官网可以下载最新的jar包和demo
* http://hc.apache.org/downloads.cgi
*/
public class TestSampleUpload4client {
public static void main(String[] args) throws ClientProtocolException, IOException{
String url = "http://192.168.1.6:8010/xxxxxxxxxxx/sample/fileUpload.action";
// 配置要 POST 的数据
MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create();
// 设置为浏览器兼容模式
multipartEntityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);
// 设置请求的编码格式
multipartEntityBuilder.setCharset(Charset.forName(HTTP.UTF_8));
ContentType TEXT_PLAIN = ContentType.create("text/plain", Charset.forName(HTTP.UTF_8));

//设置一致的编码格式极其重要，否则容易出现乱码，不管客户端是以什么语言什么方式进行调用，必须让其编码格式与接收端一致；
multipartEntityBuilder.addTextBody("userName", "admin",TEXT_PLAIN);
multipartEntityBuilder.addTextBody("psd", "admin",TEXT_PLAIN);
multipartEntityBuilder.addTextBody("mac", "ma2343344f1333",TEXT_PLAIN);
multipartEntityBuilder.addTextBody("md5", "afy67juu8776a",TEXT_PLAIN);
multipartEntityBuilder.addTextBody("type", "sample",TEXT_PLAIN);
//文件路径
File file = new File("D:\\glpt\\abc.txt");
multipartEntityBuilder.addBinaryBody("file", file);

/*
* 以下的参数提交方式也行
StringBody userName = new StringBody("admin", ContentType.create(
"text/plain", Consts.UTF_8));
StringBody password = new StringBody("admin", ContentType.create(
"text/plain", Consts.UTF_8));
// 把文件转换成流对象FileBody
FileBody bin = new FileBody(file);
multipartEntityBuilder.addPart("username", userName);
multipartEntityBuilder.addPart("password", password);
multipartEntityBuilder.addPart("file", bin);
*/
post(url,multipartEntityBuilder);
}

public static void post(String url,MultipartEntityBuilder multipartEntityBuilder) throws ClientProtocolException, IOException{
// 建立HttpPost对象
HttpPost httppost = new HttpPost(url);
HttpClient httpclient = HttpClientBuilder.create().build();
// 生成 HTTP POST 实体
HttpEntity httpEntity = multipartEntityBuilder.build();
httppost.setEntity(httpEntity);
// 发送Post,并返回一个HttpResponse对象
HttpResponse httpResponse = httpclient.execute(httppost);
// 以下两行可以得到指定的Header
// Header header = httpResponse.getFirstHeader("Content-Length");
// String headerVal = header.getValue();
HttpEntity httpEntity2 = httpResponse.getEntity();
System.out.println("httpResponse.getStatusLine().getStatusCode():"+httpResponse.getStatusLine().getStatusCode());
// 如果状态码为200,就是正常返回
if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
String result = EntityUtils.toString(httpEntity2);
// 得到返回的字符串
System.out.println(result);
// 如果是下载文件,可以用response.getEntity().getContent()返回InputStream
}else if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_MOVED_TEMPORARILY) {
// 如果状态码为302
String locationUrl = httpResponse.getLastHeader("location").getValue();
post(locationUrl,multipartEntityBuilder);
}else {
String result = EntityUtils.toString(httpEntity2);
// 得到返回的字符串
System.out.println(result);
}
}

}

/**

*另一种处理方式
* @param args
* @throws UnsupportedEncodingException
* @throws IOException
* @throws ClientProtocolException

public static void main(String[] args) throws ClientProtocolException, IOException{
// TODO Auto-generated method stub
// POST的URL
String url = "http://192.168.10.203:8010/manageplatform/sample/sampleUpload.action";
// 建立HttpPost对象
HttpPost httppost = new HttpPost(url);
// 建立一个NameValuePair数组，用于存储欲传送的参数
List<NameValuePair> params = new ArrayList<NameValuePair>();

// 添加参数
params.add(new BasicNameValuePair("userName", "admin"));
params.add(new BasicNameValuePair("psd", "admin"));
params.add(new BasicNameValuePair("mac", "mac3333333333"));
params.add(new BasicNameValuePair("md5", "md5555555555"));
params.add(new BasicNameValuePair("type", "sample"));

HttpClient httpclient = new DefaultHttpClient();
// 设置编码
httppost.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));

// 发送Post,并返回一个HttpResponse对象
HttpResponse httpResponse = httpclient.execute(httppost);
// 以下两行可以得到指定的Header
Header header = httpResponse.getFirstHeader("Content-Length");
String headerVal = header.getValue();

HttpEntity httpEntity = httpResponse.getEntity();

if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {// 如果状态码为200,就是正常返回
String result = EntityUtils.toString(httpEntity);
// 得到返回的字符串
System.out.println(result);
// 打印输出
// 如果是下载文件,可以用response.getEntity().getContent()返回InputStream
}else {
String result = EntityUtils.toString(httpEntity);
// 得到返回的字符串
System.out.println(result);
}
}
*/

}

以上例子中http请求了一个url：http://192.168.10.xxx:8010/xxxxxxxx/sample/sampleUpload.action；

其中sampleUpload.action是用struts配置的；sampleUpload.action对应的action方法如下：

/**
* HTTP接口,
* 接收下属客户端及子管理中心上传样本,保存样本文件
*
* @return
*/
public void sampleUpload() {
OutputStream out = null;
try {
out = sResponse.getOutputStream();
String result = "Response=101;";
String path = sRequest.getSession().getServletContext().getRealPath("/");
System.out.println(path);
//用户认证
String userName = sRequest.getParameter("userName");
String psd = sRequest.getParameter("psd");
//此处省略了用户权限认证的操作;
String md5 = sRequest.getParameter("md5");
String mac = sRequest.getParameter("mac");
String type = sRequest.getParameter("type");
String ip = sRequest.getRemoteAddr();

if (StringUtils.isEmpty(md5) || StringUtils.isEmpty(mac) || StringUtils.isEmpty(type)) {
result = "Response=011;";
} else {
for (int i = 0; i < fileFileName.size(); i++) {
try {
String filename = fileFileName.get(i);
String savePath = StringUtils.isEmpty(UrlAddress.getUrl(type)) ? path + "WEB-INF/uploadPath/" + type : UrlAddress.getUrl(type);
if (!new File(savePath).exists()) {
new File(savePath).mkdirs();
}

filename = savePath + "/" + filename;
// sampleName = fileFileName.get(i);
FileOutputStream fos = new FileOutputStream(filename);
InputStream is = new FileInputStream(file.get(i));
byte[] buffer = new byte[BUFFER_SIZE];
int count = 0;
while ((count = is.read(buffer)) > 0) {
fos.write(buffer, 0, count);
}
fos.close();
is.close();
filename = filename.replace('\\', '/');
result = "Response=000;";

result = sampleService.sampleUpload(type, md5, mac, filename, ip);
} catch (Exception e) {
result = "Response=101;";
e.printStackTrace();
}
}
}
//记录接口日志
sampleService.interfaceLogSave("1", mac, md5, ip, result);
//返回操作结果
out.write(result.getBytes());
out.flush();
} catch (IOException e1) {
e1.printStackTrace();
} finally {
try {
if (out != null)
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}

}
