Spring Cloud Contract在主体为列表时生成主体为空的协议

Question

Contract.make {
description "should return a list of dummy object with dummy value. Generates pact with empty json"
request {
    method GET()
    url("/dummy")
}
response {
    body("""[{"value": "Hi! I'm a dummy object ;)"}]""")
    headers {
        contentType applicationJson()
    }
    status 200
}}

Contract.make {
description "should return a list of dummy object with dummy value. Generates pact with empty body list"
request {
    method GET()
    url("/dummy")
}
response {
    body([value(value: "Hi! I'm a dummy object ;)")])
    headers {
        contentType applicationJson()
    }
    status 200
}}

我正在使用以下版本

    <spring-cloud.version>Hoxton.BUILD-SNAPSHOT</spring-cloud.version>
    <spring-cloud-contract.version>2.0.1.RELEASE</spring-cloud-contract.version>
    <pact-jvm-provider-maven.version>3.5.23</pact-jvm-provider-maven.version>

这是我的插件配置

在调试插件时，我看到分别发生的情况是：-当声明body为“”“[{...}]“”“Pact converter假定主体是String实例，因此它通过org.springframework.cloud.contract.verifier.spec.Pact.BodyConverter处的遍历方法。而且由于它以[开头，因此不解析它。

private static DslPart traverse(Object value, DslPart parent, Closure dslPropertyValueExtractor) {
    ...
    if (v instanceof String) {
        v = v.trim()
        if (v.startsWith("{") && v.endsWith("}")) {
            try {
                v = jsonSlurper.parseText(v as String)
            }
            catch (JsonException ex) { /*it wasn't a JSON string after all...*/
            }
        }
    }
    ...

    private static void processCollection(Collection values, PactDslJsonArray jsonArray, Closure dslPropertyValueExtractor) {
    values.forEach({
        Object v = it
        if (v instanceof DslProperty) {
            v = dslPropertyValueExtractor(v)
        }
        if (v instanceof GString) {
            v = ContentUtils.extractValue(v, dslPropertyValueExtractor)
        }
        if (v == null) {
            jsonArray.nullValue()
        }
        else if (v instanceof String) {
            jsonArray.string(v)
        }
        else if (v instanceof Number) {
            jsonArray.number(v)
        }
        else if (v instanceof Map) {
            PactDslJsonBody current = jsonArray.object()
            traverse(v, current, dslPropertyValueExtractor)
            current.closeObject()
        }
        else if (v instanceof Collection) {
            PactDslJsonArray current = jsonArray.array()
            traverse(v, current, dslPropertyValueExtractor)
            current.closeArray()
        }
    })
}

我在https://github.com/brjt23/contract-to-pact/tree/master上发布了一个示例，以备需要更多关于我如何构建项目的信息。

我在定义groovy合同文件时做错了什么吗？我想我对如何定义响应体有些误解了。

Answer 1

您需要在您的身体中创建一个groovy对象数组，如下所示：

正文([[值：“object1”],[值：“object2”]])

这样spring cloud contracts将生成合同所需的正确代码。
