Spring Cloud合约测试主体不匹配

Question

我正在尝试使用Spring Cloud Contract testing来测试我的分块文件上传API。

但是在消费者端，我的测试失败了，因为请求正文不匹配。

但是查看给定的错误消息，我很难理解其中的原因：

如您所见，从这一行开始：

.*--(.*)   | --m82DlcHjsDnwxSBXh7XEfqQEMEsdX7i  <<<<< Body does not match

它显示了一个不匹配的请求，这对我来说很难理解为什么！

有什么想法吗？

        <plugins>
            <plugin>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-contract-maven-plugin</artifactId>
                <version>2.2.2.RELEASE</version>
                <extensions>true</extensions>
                <configuration>
                    <baseClassForTests>
                        com.backbase.cxs.cs.c3.BaseTest
                    </baseClassForTests>

            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

这是消费者的部分：

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-contract-stub-runner</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-contract-verifier</artifactId>
            <scope>test</scope>
        </dependency>

我使用的是spring-cloud dependencyManagement：

<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Hoxton.SR4</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

Answer 1

如果不看groovy/yaml契约，就很难知道，但可能是您的正则表达式有点问题(比如额外的空格或其他什么？它在regex101.com上看起来不错)，或者您可能正在匹配硬编码字符串".--(.)“而不是一个正则表达式。

如果您使用的是groovy，请确保您有

value(regex(".*--(.*)"))

而不是仅仅

".*--(.*)"

不确定yaml中的等价物是什么。
