在我的 Grails 应用程序中，我有一个包含部分 URL 路径的配置属性，如下所示： http://apis.mycompany.com/my-api/v1/

我想使用此 URL 调用端点HttpBuilder：

class MyApiService {
    @Value('${myApiUrl}')
    String myApiUrl

    def http

    @PostConstruct()
    init() {
        http = HttpBuilder.configure {
            request.uri = myApiUrl
        }
    }

    def getData() {
        http.get() {
            // This doesn't work!!
            request.uri.path = 'resource/data'
        }
    }
}

request.uri.path擦除现有路径段：

java.lang.RuntimeException: java.net.URISyntaxException: Relative path in absolute URI: http://apis.mycompany.comresource/data

我能够解决这个问题：

request.raw = "${myApiUrl}resource/data"

...但我无法让 Ersatzraw在我的 Spock 测试中使用：

def setup() {
    ersatz = new ErsatzServer()
    service.myApiUrl = ersatz.httpUrl + '/'
}

void "getData() - should call the endpoint"() {
    given:
    def jsonData = '[{"person": "Someone"}]'

    ersatz.expectations {
        get("/resource/data") {
            called 1
            responder {
                content jsonData, 'application/json;chartset=UTF-8'
            }
        }
    }

    when:
    def result = service.getData()

    then:
    result == jsonData
}

分配给的 URLraw是：http://localhost:-1/resources/data

这会导致异常：

java.lang.IllegalArgumentException: protocol = http host = null

    at com.mycompany.MyApiService.getData(...)
    at com.mycompany.MyApiServiceSpec.getData(...)

这是 HttpBuilder 中的错误，还是我做错了？帮助表示赞赏！

更新：

我以为 Ersatz 会在构建时开始，但事实证明我错了。在使用 URL 之前调用start()修复了 -1 端口号：

def setup() {
    ersatz = new ErsatzServer()
    ersatz.start()
    service.myApiUrl = ersatz.httpUrl + '/'
}

现在，构建器正在获取一个看似有效的 URL： http://localhost:52180/resources/data

...但是 Ersatz 服务器给出的消息是期望不匹配。

java.lang.AssertionError: Expectations for Expectations (ErsatzRequest): <GET>, "/resources/data" were not met.. Expression: (com.stehno.ersatz.impl.ErsatzRequest -> com.stehno.ersatz.impl.ErsatzRequest) r.verify()

    at com.stehno.ersatz.impl.ExpectationsImpl.verify_closure2(ExpectationsImpl.groovy:365)
    at com.stehno.ersatz.impl.ExpectationsImpl.verify(ExpectationsImpl.groovy:364)
    at com.stehno.ersatz.ErsatzServer.verify(ErsatzServer.groovy:522)
    at com.mycompany.MyApiServiceSpec.cleanup(...)

Ersatz 文档表明应该打印出不匹配的请求，但它只打印上面的堆栈跟踪（和 HttpNotFoundException）。

对我来说，它只是附加路径而不是分配它：

request.uri.path += 'resource/data'
