英文:
WireMock - How to Include Request JSON Body Into the Response Body?
问题
我迄今为止取得了什么成就？
我正在使用 WireMock 与 Spring Boot 应用程序以及 JUNIT 5 进行测试。
我正在为 test 端点设置自定义的请求和响应 JSON 负载：
请求负载：
{
"merchantId": "xxxx",
"data": [
{
"id": "unique-id-1",
"sensitiveData": "xxxxxx"
},
// 其他数据...
]
}
响应负载：
{
"status": "SUCCESS",
"tokens": [
{
"id": "unique-id-1",
"token": "xxxxxxxxxx"
},
// 其他数据...
]
}
我想要实现什么？
由于我的 JSON 请求负载是动态的，我希望在响应中也创建一个动态的 JSON 负载，其中 JSON 中的令牌值是静态的，但 JSON 中的 id 值是基于请求负载的 id 值的动态值。
@SpringBatchTest
class FileTest {
private WireMockServer wireMockServer;
@BeforeEach
void setUp() {
wireMockServer =
new WireMockServer(options().extensions(new ResponseTemplateTransformer(true)).port(PORT));
WireMock.configureFor("localhost", PORT);
wireMockServer.start();
}
@AfterEach
void tearDown() {
wireMockServer.stop();
}
@Test
void testEndToEndFlowForSpringBatch() {
final String body = ResponsePayload.getResponseJsonPayload();
wireMockServer.addStubMapping(
stubFor(
post(urlPathMatching("/test"))
.willReturn(
aResponse()
.withBody(body)
.withStatus(200)
.withTransformers("response-template"))));
// 更多代码
}
}
ResponsePayload.getResponseJsonPayload() 包含以下值：
{
"response": "SUCCESS",
"tokens": [
{
"id": "{{jsonPath request.body '$.data[0].id'}}",
"token": "xxxxxx"
},
{
"id": "{{jsonPath request.body '$.data[1].id'}}",
"token": "xxxxxxx"
},
// 其他数据...
]
}
什么不起作用？
当我调试程序时，我可以看到存根正在引发以下错误：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/>
<title>Error 500 </title>
</head>

<h2>What I have achieved so far?</h2>
I'm using WireMock with Spring Boot Application using the JUNIT 5.
I am stubbing the test endpoint with the custom Request and Response JSON payload:
REQUEST PAYLOAD:
{
"merchantId": "xxxx",
"data": [
{
"id": "unique-id-1",
"sensitiveData": "xxxxxx",
},
...
...
]
}
RESPONSE PAYLOAD:
{
"status": "SUCCESS",
"tokens": [
{
"id": "unique-id-1",
"token": "xxxxxxxxxx",
},
...
...
]
}
<h2>What I'm trying to achieve?</h2>
Since my JSON Request payload is dynamic. I want to create a dynamic JSON Payload in response as well where tokens values in JSON are static but the id's value in JSON is dynamic based on the request payload's id value.
@SpringBatchTest
class FileTest{
private WireMockServer wireMockServer;
BeforeEach
void setUp() {
wireMockServer =
new WireMockServer(options().extensions(new
ResponseTemplateTransformer(true)).port(PORT));
WireMock.configureFor("localhost", PORT);
wireMockServer.start();
}
@AfterEach
void tearDown() {
wireMockServer.stop();
@Test
void testEndToEndFlowForSpringBatch() {
final String body = ResponsePayload.getResponseJsonPayload();
wireMockServer.addStubMapping(
stubFor(
post(urlPathMatching("/test"))
.willReturn(
aResponse()
.withBody(body)
.withStatus(200)
.withTransformers("response-template"))));
//morecode
}
<h6>ResponsePayload.getResponseJsonPayload() contains below value:</h6>
{
"response": "SUCCESS",
"tokens": [
{
"id": "{{jsonPath request.body '$.data[0].id'}}",
"token": "xxxxxx",
},
{
"id": "{{jsonPath request.body '$.data[1].id'}}",
"token": "xxxxxxx",
},
..
]
}
<h2>What is not working?</h2>
When I am debugging the program I can see the stub is throwing following error:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/>
<title>Error 500 </title>
</head>
<body>
<h2>HTTP ERROR: 500</h2>
<p>Problem accessing /test. Reason:
<pre> wiremock.com.github.jknack.handlebars.HandlebarsException: inline@1e0c0274:5:21: could not find helper: &apos;jsonPath&apos;
&quot;id&quot;: &quot;{{jsonPath request.body &apos;$.merchantId&apos;}}&quot;,
^

I've already read below answers but couldn't find a way of using the jsonPath:
- https://stackoverflow.com/questions/36289085/wiremock-variable-substitution-in-json-response
- https://stackoverflow.com/questions/50035502/wiremock-how-configure-a-json-to-show-request-headers-in-the-response

Any help would be appreciable.
Thanks!

我只需要升级WireMock的版本，以解决问题。将版本从<version>2.6.0</version>升级到最新版本<version>3.0.0-beta-9</version>。
依赖项：
<dependency>
<groupId>com.github.tomakehurst</groupId>
<artifactId>wiremock-standalone</artifactId>
<version>3.0.0-beta-9</version>
<scope>test</scope>
</dependency>
你可以在Maven存储库中获取最新版本：Maven Store
另外，可以这样创建服务器：
private WireMockServer wireMockServer;
@BeforeEach
void setUp() {
wireMockServer =
new WireMockServer(
options()
.extensions(new ResponseTemplateTransformer(true))
.port(PORT));
wireMockServer.start();
}
在存根中：
@Test
void testWireMockServerIsUp() {
wireMockServer.stubFor(
post(urlPathMatching("/test"))
.willReturn(
aResponse().withBody(body).withStatus(200)));
}
英文:
All I needed to fix the issue was to upgrade the version of WireMock from <version>2.6.0</version> to the latest one <version>3.0.0-beta-9</version>.
Dependency:
<dependency>
<groupId>com.github.tomakehurst</groupId>
<artifactId>wiremock-standalone</artifactId>
<version>3.0.0-beta-9</version>
<scope>test</scope>
</dependency>
You can get the latest one from the Maven store here: Maven Store
Also, create the server this way:
private WireMockServer wireMockServer;
@BeforeEach
void setUp() {
wireMockServer =
new WireMockServer(
options()
.extensions(new ResponseTemplateTransformer(true))
.port(PORT));
wireMockServer.start();
}
And in the stub:
@Test
void testWireMockServerIsUp() {
wireMockServer.stubFor(
post(urlPathMatching("/test"))
.willReturn(
aResponse().withBody(body).withStatus(200)));
}
