karate - 空手道：在 json 中解析变量的奇怪问题

问题描述

我今天更新IDE后发现了这个问题：

Scenario: test scenario
    * def amqpHost = '10.10.10.10'
    * def amqpPort = 5555
    * def amqpUser = 'tesetUser'
    * def amqpPass = 'testPass'
    * def amqpExchange = 'test.rabbitmq.exchange'
    * def amqpQueueName = 'test.rabbitmq.queue'
    * def amqpRoute = 'test.rabbitmq.route'
    * def amqpVirtualHost = '/'

    * print "PORT: " + amqpPort
    * print "PORT: " + amqpUser
    * print "PORT: " + amqpPass
    * print "PORT: " + amqpExchange
    * print "PORT: " + amqpQueueName

    * def inputParams = { fleetId: '#(fleetId)', host: '#(amqpHost)', port:'#(amqpPort)', user:'#(amqpUser)', password: '#(amqpPassword)', exchange: '#(amqpExchange)', route: '#(amqpRoute)', virtual_host: '#(amqpVirtualHost)' }
    * print "INPUT: " + inputParams

输出是：

[print] PORT: 5555
[print] PORT: tesetUser
[print] PORT: testPass
[print] PORT: test.rabbitmq.exchange
[print] PORT: test.rabbitmq.queue
[print] INPUT: {fleetId=#(fleetId), host=10.10.10.10, port=5555, user=tesetUser, password= '#(amqpPassword)', exchange= '#(amqpExchange)', route= '#(amqpRoute)', virtual_host= '#(amqpVirtualHost)'}

amqpPassword 和其余变量未正确解析。但是当我删除 json 中的所有空格 ("host: '#(amqpHst)'" > "host:'#(amqpHst)'") 时：

* def inputParams = { fleetId:'#(fleetId)', host:'#(amqpHost)', port:'#(amqpPort)', user:'#(amqpUser)', password:'#(amqpPassword)', exchange:'#(amqpExchange)', route:'#(amqpRoute)', virtual_host:'#(amqpVirtualHost)' }

我得到了结果：

{fleetId=#(fleetId), host=10.10.10.10, port=5555, user=tesetUser, password=#(amqpPassword), exchange=test.rabbitmq.exchange, route=test.rabbitmq.route, virtual_host=/}

看起来这个问题出现在我今天更新 IntelliJ Idea 或其中一个插件之后。我使用：Idea 2018.3.5 CE (build #IC-183.591221) Cucumber for Java v183.5429.1

解决方案

首先 - 请注意，有一种非常方便的方法可以使用print漂亮打印 JSON（如果适用）的关键字，请参见下文：

* print "PORT:", amqpPort
* print "PORT:", amqpUser
* print "PORT:", amqpPass
* print "PORT:", amqpExchange
* print "PORT:", amqpQueueName

* def inputParams = { fleetId: '#(fleetId)', host: '#(amqpHost)', port:'#(amqpPort)', user:'#(amqpUser)', password: '#(amqpPass)', exchange: '#(amqpExchange)', route: '#(amqpRoute)', virtual_host: '#(amqpVirtualHost)' }
* print "INPUT:", inputParams

我得到：

[print] INPUT: {
  "fleetId": "#(fleetId)",
  "host": "10.10.10.10",
  "port": 5555,
  "user": "tesetUser",
  "password": "testPass",
  "exchange": "test.rabbitmq.exchange",
  "route": "test.rabbitmq.route",
  "virtual_host": "/"
}

所以我觉得很好。一个建议，为什么不将整个定义inputParams为 JSON 本身？您甚至可以从文件中读取它。并注意如何使用foo.bar点符号：

* def inputParams = { fleetId: 'foo', host: '10.10.10.10', port: 5555, user: 'tesetUser', password: 'testPass', exchange: 'test.rabbitmq.exchange', route: 'test.rabbitmq.route', virtual_host: '/' }

* print "port:", inputParams.port
* print "user:", inputParams.user
* print "pass:", inputParams.password
* print "exch:", inputParams.exchange

* print "INPUT:", inputParams

我认为这根本与 IDE 无关 - 如果您仍然看到问题，请按照以下流程操作：https ://github.com/intuit/karate/wiki/How-to-Submit-an-Issue
