Jmeter 接口测试中，通常要校验请求报文返回的结果，对于返回的结果格式，有的是xml,有的是json。这里对返回报文是否为json格式进行校验。
以下是接口返回报文：
{
"accidentNo": "AN1111",
"auditReport": {
"auditRuleTriggers": [{
"actualValue": " 次数：\n 137\n",
"auditScore": 10,
"itemInfoList": [],
"itemName": "本碰撞点：1",
"redLineType": "00",
"ruleName": "历史出险碰撞点相同",
"ruleNo": "A102010046",
"ruleType": "02",
"ruleValue": " 次数：\n 6\n"
},
{
"actualValue": " 24.04\n",
"auditScore": 20,
"itemInfoList": [{
"claimItemUniqueId": null,
"itemName": "xxxx栅",
"itemType": "01",
"materialFeeAfterDiscount": null,
"quantity": 1,
"removeLaborFeeDiscount": 24.04,
}],
"itemName": "xxxx栅\n",
"redLineType": "00",
"ruleName": "单项维修金额超过系统价",
"ruleNo": "A101050009",
"ruleType": "01",
"ruleValue": " 24.00\n"
}]
},
"claimUniqueId": "CN070210",
"interfaceCode": "ClaimPush",
"message": "success",
"resultCode": "000"
}
校验上述报文格式，详细步骤：
1、使用在线json schema生成工具自动生成上述报文的schema
地址：https://jsonschema.net/。将生成的内容保存为responseSchema.json文件，原返回结果保存为auditReport.json
{
"type": "object",
"definitions": {},
"properties": {
"accidentNo": {
"type": "string"
},
"auditReport": {
"type": "object",
"properties": {
"auditRuleTriggers": {
"type": "array",
"items": {
"type": "object",
"properties": {
"actualValue": {
"type": "string"
},
"auditScore": {
"type": "integer"
},
"itemInfoList": {
"type": "array"
},
"itemName": {
"type": "string"
},
"redLineType": {
"type": "string"
},
"ruleName": {
"type": "string"
},
"ruleNo": {
"type": "string"
},
"ruleType": {
"type": "string"
},
"ruleValue": {
"type": "string"
}
}
}
}
}
},
"claimUniqueId": {
"type": "string"
},
"interfaceCode": {
"type": "string"
},
"message": {
"type": "string"
},
"resultCode": {
"type": "string"
}
}
}
2、新建maven工程，将上述两个文件放置main录的resources下，并导入包：json-schema-validator、fastjson
<!-- 用于校验json报文格式-->
<dependency>
<groupId>com.github.fge</groupId>
<artifactId>json-schema-validator</artifactId>
<version>2.2.6</version>
</dependency>
<!-- 用于json报文的转换-->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.40</version>
</dependency>
3、新增类 JsonSchemaValidator，代码如下
package com.sc;
import com.fasterxml.jackson.databind.JsonNode;
import com.github.fge.jackson.JsonLoader;
import com.github.fge.jsonschema.core.exceptions.ProcessingException;
import com.github.fge.jsonschema.core.report.ProcessingReport;
import com.github.fge.jsonschema.main.JsonSchema;
import com.github.fge.jsonschema.main.JsonSchemaFactory;
import java.io.IOException;
public class JsonSchemaValidator {
private final static JsonSchemaFactory factory = JsonSchemaFactory.byDefault();
public static ProcessingReport validatorSchema(String response) throws IOException, ProcessingException {
JsonSchema jsonSchema = factory.getJsonSchema(JsonLoader.fromResource("/responseSchema.json"));
JsonNode jsonNode = JsonLoader.fromString(response);
ProcessingReport report = jsonSchema.validate(jsonNode);
return report;
}
}
/**
* 在解析响应前，使用JsonSchema对响应的格式进行校验，如果校验失败，则直接返回 fail
*
* @return 校验结果
*/
public static boolean checkJsonFormat() throws IOException, ProcessingException {
ProcessingReport report = JsonSchemaValidator.validatorSchema(response);
return report.isSuccess();
}
说明：
1）、方法validatorSchema
先通过JsonSchemaFactory.byDefault()获取到JsonSchemaFactory
加载JsonSchema，即模板
将接口的返回结果转换成JsonNode
最后使用加载的JsonSchema校验JsonNode
2）、方法checkJsonFormat
使用validatorSchema的返回结果，调用ProcessingReport 的isSuccess方法，返回校验结果
4、新增测试类，校验auditReport.json格式
public class Test{
public static void main(String[] args) throws IOException, ProcessingException {
String response = FileUtils.readFileToString(new File("./src/main/resources/auditReport.json"),"utf-8");
JsonResponse jsonResponse = new JsonResponse(response);
boolean flag = JsonSchemaValidator.checkJsonFormat(response);
if(flag){
System.out.println("响应结果格式符合要求;");
}else{
System.out.println("响应结果格式不符合要求！！;");
}
}
}
运行，结果

ok，准备工作完成。将上述工程打包，引入到jmeter，直接在beanshell中调用上述方法即可。
