【web】Spring RestTemplate送出時設定POST請求參數

在web開發時程序遇到需要編寫一些小的測試用例用于測試api接口是否可用，此時使用Spring架構的開發者大多會想到使用RestTemplate。本文實作一個使用RestTemplate發起GET請求，同僚設定GET請求的http頭的示例。

1、建立測試類的基類

建立一個測試類的基類BaseTester，用于導入測試類的配置檔案，本例中配置檔案使用的時java注解的config類。基類代碼如下：

package api.landsem.tester.ram;

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { EmptyConfiguration.class })
public class BaseTester {

}
           

2、建立配置類

上面建立的測試基類中導入了一個名為EmptyConfiguration的配置類，該配置類的代碼如下：

package api.landsem.tester.ram;

import org.springframework.context.annotation.Configuration;

@Configuration
public class EmptyConfiguration {

}
           

3、建立測試用例

測試用例向一個指定的api發起http請求，并設定post請求的參數，代碼如下：

package api.landsem.tester.ram.api;

import java.util.Date;

import org.apache.log4j.Logger;
import org.junit.Test;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.client.RestTemplate;

import api.landsem.ram.factory.SignatureHelper;
import api.landsem.tester.ram.BaseTester;
import api.landsem.utils.LocalDateUtils;
import api.landsem.utils.TokenUtils;

public class CertificateRegistApiTester extends BaseTester{
	private final static Logger logger = Logger.getLogger(CertificateRegistApiTester.class);
	
	private final static String testKey = "LSadsfdslfm";
	private final static String testSecret = "LSerkfdksvdsf";
	private final static int intent = 101;
	private final static String code = "2asfd5f69699532325686";
	private final static String number = "665533255555";
	private final static String salt = "10";

       @Test
	public void test() {
		logger.info("call test.");
		final String url = "http://192.168.1.245:8082/ram/ram/v1/certificates";
		RestTemplate template = new RestTemplate();		
		HttpHeaders headers = new HttpHeaders();
		headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
				

		MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>();
		map.add("key", testKey);
		map.add("intent", String.valueOf(intent));
		map.add("number", number);
		map.add("code", code);
		map.add("signature", signature);
		HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map,null);
		ResponseEntity<String> response = template.postForEntity( url, request , String.class );		
		logger.info("response="+response.getBody());
	}

}
