POST 期间请求正文中的变量替换为 {}

Question

我正在使用空手道 DSL（版本 0.6.1.1），我有以下情况：

  Scenario:
    Given url baseURL
    * def email = "test_email@test_domain.com"
    * def query = "SELECT * FROM public.users where username='" + email + "' ORDER BY user_id ASC"
    * def dbUrl = databaseUrl + "databaseName"
    * def config = { username: '#(databaseUsername)', password: '#(databasePassword)', url: '#(dbUrl)', driverClassName: 'org.postgresql.Driver' }
    * def DbUtils = Java.type('utility.database.DbUtils')
    * def db = new DbUtils(config)
    * def results = db.readRow(query)
    * def supplierId = results.user_id
    * print "SUPPLIERID: " + supplierId

    Given path '/path/to/endpoint'
    And header content-type = 'application/json'
    And request { supplierId: #(supplierId) }
    When method POST
    Then status 200

utility.database.DbUtils 是自定义的 class，readRow() 是 class 的单行成员，returns 是 JdbcTemplate.queryForMap(query) 的结果.

运行这个场景给出了如下日志：


    10:53:17.477 [main] INFO  com.intuit.karate - [print] SUPPLIERID: 957750e7-ee6b-486d-977c-05c8ac7bb589
    10:53:17.506 [main] INFO  com.intuit.karate - request:{
      "supplierId": 957750e7-ee6b-486d-977c-05c8ac7bb589
    }
    10:53:18.372 [main] DEBUG com.intuit.karate - 
    1 > POST <a href="http://baseurl.com/path/to/endpoint" rel="nofollow noreferrer">http://baseurl.com/path/to/endpoint</a>
    1 > Accept-Encoding: gzip,deflate
    1 > Connection: Keep-Alive
    1 > Content-Length: 17
    1 > Content-Type: application/json
    1 > Host: base.url.com
    1 > User-Agent: Apache-HttpClient/4.5.3 (Java/1.8.0_162)
    {"supplierId":{}}
</pre>

可以看到一开始request body中supplierId的值为957750e7-ee6b-486d-977c-05c8ac7bb589。但是，一旦 POST 生成，supplierId 就只是 {}。这似乎与 supplierId 由数据库调用填充这一事实有关。如果我用简单的 * def supplierId = "957750e7-ee6b-486d-977c-05c8ac7bb589" 替换对数据库的调用，请求正文会按预期显示。

为什么在调用 POST 时 supplierId 被替换为 {}，我该如何阻止它这样做？

Answer 1

看来您的嵌入式表达式语法有误。我认为这一更改应该修复，请注意字符串引号：

And request { supplierId: '#(supplierId)' }

Answer 2

看起来是类型转换问题。我通过将 * def supplierId = results.user_id 替换为 * string supplierId = results.user_id.

使其正常工作

POST 期间请求正文中的变量替换为 {}

Variable in request body replaced with {} during POST
