接口测试中，经常会遇到一次发送多个http请求，然后获取响应结果中的重点字段。并将字段的值写入到某个文件中，以便查看各个请求的具体响应内容。
本文场景：从excel中读取要测试的VIN码，发送Http请求，调用接口，实现车辆VIN码定型并将定型结果处理后，写入到excel中。
具体实现步骤：
1、使用Excel4j工具包下的readExcel2List方法读取存取VIN码的excel，并将其存储到List中
2、使用httpclient工具包，创建post请求，并遍历存储VIN的List，将VIN传入到要发送的post请求中。
HttpClientUtils类:
package com.sc.vmi;
import org.apache.http.HttpEntity;
import org.apache.http.NameValuePair;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
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.impl.conn.PoolingHttpClientConnectionManager;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.protocol.HTTP;
import org.apache.http.util.EntityUtils;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
public class HttpClientUtils{
// private static CookieStore cookieStore = new BasicCookieStore();
// private static CloseableHttpClient httpClient = HttpClients.custom().setDefaultCookieStore(cookieStore).build();
private static CloseableHttpClient httpClient;
private static CloseableHttpResponse httpResponse = null;
private static HttpEntity postEntity = null;
static {
PoolingHttpClientConnectionManager manager = new PoolingHttpClientConnectionManager();
manager.setMaxTotal(200); //连接池最大并发连接数
manager.setDefaultMaxPerRoute(200);//单路由最大并发数,路由是对maxTotal的细分
httpClient = HttpClients.custom().setConnectionManager(manager).build();
}
public static String doPost(String url, Map<String, Object> params){
HttpPost post = new HttpPost(url);
post.addHeader(HTTP.CONTENT_ENCODING, "UTF-8");
String ret = null;
try {
if (params != null) {
List<NameValuePair> list = new ArrayList<NameValuePair>();
for (Map.Entry<String, Object> entry : params.entrySet()) {
list.add(new BasicNameValuePair(entry.getKey(), entry.getValue().toString()));
}
postEntity = new UrlEncodedFormEntity(list);
post.setEntity(postEntity);
}
httpResponse = httpClient.execute(post);
if (httpResponse.getStatusLine().getStatusCode() == 200) {
ret = EntityUtils.toString(httpResponse.getEntity(), "UTF-8");
} else {
throw new Exception(
"System level error, Code=[" + httpResponse.getStatusLine().getStatusCode() + "].");
}
} catch (Exception e) {
e.printStackTrace();
}
return ret;
}
public static void close(){
if(postEntity!=null) {
try {
EntityUtils.consume(postEntity);
} catch (IOException e) {
}
}
if (httpResponse != null) {
try {
httpResponse.close();
} catch (IOException e) {
}
}
}
}
这里的post请求需要发送两次，在进行VIN定型之前，需要指定用户登录，然后再定型。
3、创建VIN定型 响应结果的VO，将post请求的响应结果中对应字段mapping到VO的对应字段
VO：VMIResult类
package com.sc.vmi;
import com.github.crab2died.annotation.ExcelField;
public class VMIResult {
@ExcelField(title = "vin")
private String vin;
@ExcelField(title = "resultCode")
private String resultCode;
@ExcelField(title = "resultMsg")
private String resultMsg;
@ExcelField(title = "vehicleSubModelId")
private String vehicleSubModelId;
public String getVin() {
return vin;
}
public void setVin(String vin) {
this.vin = vin;
}
public String getResultCode() {
return resultCode;
}
public void setResultCode(String resultCode) {
this.resultCode = resultCode;
}
public String getResultMsg() {
return resultMsg;
}
public void setResultMsg(String resultMsg) {
this.resultMsg = resultMsg;
}
public String getVehicleSubModelId() {
return vehicleSubModelId;
}
public void setVehicleSubModelId(String vehicleSubModelId) {
this.vehicleSubModelId = vehicleSubModelId;
}
@Override
public String toString() {
return "VMIResult{" +
"vin='" + vin + '\'' +
", resultCode='" + resultCode + '\'' +
", resultMsg='" + resultMsg + '\'' +
", vehicleSubModelId='" + vehicleSubModelId + '\'' +
'}';
}
}
4、使用Excel4j工具包下的exportObjects2Excel方法将响应结果指定字段的值写入到excel中
VMITest 类:
package com.sc.vmi;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.github.crab2died.ExcelUtils;
import java.io.File;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class VMITest {
static List<VMIResult> stringList = new ArrayList<VMIResult>();
public static void main(String[] args) {
getVMIResult();
}
private static void login() {
Map<String, Object> map = new HashMap<String, Object>();
map.put("j_username", "vip");
map.put("j_password", "1");
map.put("captchaStr", "1");
String loginUrl = "http://**.**.**:8080/web-suite/j_spring_security_check";
HttpClientUtils.doPost(loginUrl,map);
}
private static String vtm(String vin) {
Map<String, Object> map = new HashMap<String, Object>();
map.put("vin", vin);
map.put("claimId", "589");
String vtmUrl = "http://**.**.**:8080/web-suite/metadata/getQuestionByVin";
return HttpClientUtils.doPost(vtmUrl,map);
}
private static void getVMIResult(){
String filePath = System.getProperty("user.dir")+File.separator+ "data"+File.separator+"vin.xlsx";
String destPath = System.getProperty("user.dir")+File.separator+ "data"+File.separator+"vinResult.xlsx";
try {
List<List<String>> list = ExcelUtils.getInstance().readExcel2List(filePath);
for(List<String> ll : list) {
for (String vin : ll) {
String[] vinRes = vtmPost(vin).split(";");
VMIResult vmiResult = new VMIResult();
vmiResult.setVin(vinRes[0]);
vmiResult.setResultCode(vinRes[1]);
vmiResult.setResultMsg(vinRes[2]);
vmiResult.setVehicleSubModelId(vinRes[3]);
stringList.add(vmiResult);
}
}
System.out.println(stringList.toString());
ExcelUtils.getInstance().exportObjects2Excel(stringList,VMIResult.class,destPath);
} catch (Exception e) {
e.printStackTrace();
}
}
private static String vtmPost(String vin){
login();
String result = vtm(vin);
JSONObject jsonObject = (JSONObject) JSON.parse(result);
String resultCode = jsonObject.get("resultCode").toString();
String resultMsg = jsonObject.get("resultMsg").toString();
String vehicleSubModelId = getStringValue(jsonObject,"vehicleSubModelId");
if(vehicleSubModelId.equals("") && "1".equals(resultCode)){
vehicleSubModelId = "多个款型";
resultMsg = "二步定款";
}
if(resultCode.equals("-3")){
vehicleSubModelId = "无";
resultMsg = "定型失败";
}
if(resultCode.equals("-20")){
vehicleSubModelId = "无";
}
String str = vin+";"+resultCode+";"+resultMsg+";"+vehicleSubModelId;
HttpClientUtils.close();
return str;
}
private static String getStringValue(JSONObject jsonObject,String key){
return jsonObject.get(key)==null?"":jsonObject.get(key).toString();
}
}
写入到excel后的响应结果如下：
