如何使用空手道框架将字节数组作为 Json 的一部分发送

Question

我有一个端点使用 Json 和 2 个属性，比如

{id='12344', data=byte_array}

所以我写了一个测试

Feature: submitted request

Scenario: submitted request
* def convertToBytes =
"""
function(arg) {
    var StreamUtils = Java.type('my.utils.StreamUtils');
    // it reads stream and convert it to a byte array
    return StreamUtils.getBytes(arg);
}
"""

 Given url 'http://my-server/post'
 And def image = convertToBytes(read('classpath:images/image_1.jpg'));
 And request {id:1, data: "#(image)"}
 When method POST
 Then status 200

然而空手道有一个例外，没有太多细节

ERROR com.intuit.karate - http request failed: [B cannot be cast to [Ljava.lang.Object;

如何使用空手道提交字节数组作为 Json 的一部分？

Answer 1

我认为你做不到。不过 whole request should be binary (byte-array) or you do a multi-part request, where binary is Base64 encoded. As far as I know you can't put binary inside JSON. There is something called Binary JSON。

编辑：假设 byte[] 必须是 Base64 编码后：

Background:
    * url demoBaseUrl
    * def Base64 = Java.type('java.util.Base64')

Scenario: json with byte-array
    Given path 'echo', 'binary'
    And def encoded = Base64.encoder.encodeToString('hello'.bytes);
    And request { message: 'hello', data: '#(encoded)' }
    When method post
    Then status 200
    And def expected = Base64.encoder.encodeToString('world'.bytes);
    And match response == { message: 'world', data: '#(expected)' }

我刚刚将此测试添加到空手道演示中，并且运行良好。这是 commit.
