通达信交易接口php-Http传输json进行服务端接口与客户端对接以及restful实现

话不多说，直接贴代码，照写就好了

服务端接口编写，我用的是springmvc,服务端接口其实和平时web开发一样，就是返回出json就好了，还有就是接受数据也是json，方法如下：

@Controller

@RequestMapping('/user')

public class UserController {


@Autowired

private UserService userservice;

@RequestMapping('/getUserByName')

public @ResponseBody User getUserByName(HttpServletRequest request) throws IOException{

StringBuffer str = new StringBuffer();

try {

BufferedInputStream in = new BufferedInputStream(request.getInputStream());

int i;

char c;

while ((i=in.read())!=-1) {

c=(char)i;

str.append(c);

}

}catch (Exception ex) {

ex.printStackTrace();

}

JSONObject obj= JSONObject.fromObject(str.toString());

System.out.println(obj.get('name'));

User user= userservice.getUserByName(obj.get('name').toString());

return user;

}


}

实现的是一个通过服务端接收客户端json{“name”:'cwh'}名字name进行查询操作，然后给客户端返回json;

客户端实现如下：

import java.io.IOException;


import net.sf.json.JSONObject;

import net.spring.model.User;


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.StringEntity;

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

import org.apache.http.util.EntityUtils;

import org.junit.Test;


public class Client {

@Test

public void HttpPostData() {

try {

HttpClient httpclient = new DefaultHttpClient();

String uri = 'http://localhost:8080/springMVC/user/getUserByName';

HttpPost httppost = new HttpPost(uri);

//添加http头信息

httppost.addHeader('Authorization', 'your token'); //认证token

httppost.addHeader('Content-Type', 'application/json');

httppost.addHeader('User-Agent', 'imgfornote');

JSONObject obj = new JSONObject();

obj.put('name', 'cwh');

httppost.setEntity(new StringEntity(obj.toString()));

HttpResponse 通达信交易接口php,response;

通达信交易接口php,response = httpclient.execute(httppost);

//检验状态码，如果成功接收数据

int code = 通达信交易接口php,response.getStatusLine().getStatusCode();

System.out.println(code+'code');

if (code == 200) {

String rev = EntityUtils.toString(通达信交易接口php,response.getEntity());//返回json格式： {'id': '','name': ''}

obj= JSONObject.fromObject(rev);


User user = (User)JSONObject.toBean(obj,User.class);

System.out.println('返回数据==='+user.toString());

}

} catch (ClientProtocolException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

} catch (Exception e) {

e.printStackTrace();

}

}

}

ok,把服务端部署到tomcat

运行客户端：返回数据成功

当然也可以用RESTFUL风格来实现

服务端可以这么编写：

@RequestMapping('/getUserByName/{name}')

public @ResponseBody User getUserByName(@PathVariable('name')String name) throws IOException{

User user= userservice.getUserByName(name);

return user;

}

Http传输json进行服务端接口与客户端对接以及restful实现

那么客户端请求就这么写了：

public void HttpPostData() {

try {

HttpClient httpclient = new DefaultHttpClient();

String uri = 'http://localhost:8080/springMVC/user/getUserByName/cwh';

HttpPost httppost = new HttpPost(uri);

JSONObject obj = new JSONObject();


HttpResponse 通达信交易接口php,response;

通达信交易接口php,response = httpclient.execute(httppost);

//检验状态码，如果成功接收数据

int code = 通达信交易接口php,response.getStatusLine().getStatusCode();

System.out.println(code+'code');

if (code == 200) {

String rev = EntityUtils.toString(通达信交易接口php,response.getEntity());//返回json格式： {'id': '','name': ''}

obj= JSONObject.fromObject(rev);

User user = (User)JSONObject.toBean(obj,User.class);

System.out.println('返回数据==='+user.toString());

}

} catch (ClientProtocolException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

} catch (Exception e) {

e.printStackTrace();

}

}
