带多参数的条件GET请求出现查询非法字符问题排查

问题原因 #

你的GET请求URL里，查询参数groups的值是JSON数组[["Movie"],["Show"]]，但方括号[]、双引号"这类特殊字符直接放在URL中未做URL编码，服务器会判定为非法字符，导致请求失败。

解决方案 #

在Karate框架中，推荐以下两种处理方式：

方式1：用Karate参数化语法自动编码 #

不要直接在URL里拼接参数，改用param关键字指定查询参数，Karate会自动对特殊字符做URL编码：

Given header x-apisignatures = '543aba07839'
And header ssotoken = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiJ9.eyJ1bmlxdWUiOiJjYTM4MDAzZS0wYThiLTQ3YjktOWFjNS00YzMyN2MwNTUyMGYiLCJ1c2VyVHlwZSI6IlJJTHBlcnNvbiIsImF1dGhMZXZlbCI6IjIwIiwiZGV2aWNlSWQiOiJlZWIxOGRlOGRiNjE3MDg4MjViNTdjNGU5NDg1ZmFjYTU1MGE1OTBkY2Y1MjIzNzkyYzUwYjVhZWRjZGI5ZmUxNDQxZTFiMzhmZWI2NDFhZmUwNGI3NGY0NDA5OWMzZGQwZWI0OTRiZjgwMTYxOWYyNTAyNjI2YTJjZjdkMTZmZCIsImp0aSI6IjFmN2IwODkxLTJkMGUtNDBhZS04MWJiLWQwODVjY2NhOGYyZSIsImlhdCI6MTY2NDI3Njk0NH0.6Q7CPtQIN0uB1ZbVQBj5dshqioop3dJKEpla5DQS5K5qtRPw38SxTEJ1f1DJ_Ka_sgMp_fdh9EEABipTgtgMqg'
And header uniqueid = 'ca38003e-0a8b-47b9-9ac5-4c327c05520f'
And header x-page = 'Home'
Given url 'https://jiocinemaqa-api.jio.ril.com/user/v1/watchlist'
And param groups = '[["Movie"],["Show"]]'
When method GET
Then status 200
* print response

方式2：手动URL编码参数值 #

如果需要手动拼接URL，先将groups的值编码为%5B%5B%22Movie%22%5D%2C%5B%22Show%22%5D%5D，替换到URL中：

Given header x-apisignatures = '543aba07839'
And header ssotoken = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiJ9.eyJ1bmlxdWUiOiJjYTM4MDAzZS0wYThiLTQ3YjktOWFjNS00YzMyN2MwNTUyMGYiLCJ1c2VyVHlwZSI6IlJJTHBlcnNvbiIsImF1dGhMZXZlbCI6IjIwIiwiZGV2aWNlSWQiOiJlZWIxOGRlOGRiNjE3MDg4MjViNTdjNGU5NDg1ZmFjYTU1MGE1OTBkY2Y1MjIzNzkyYzUwYjVhZWRjZGI5ZmUxNDQxZTFiMzhmZWI2NDFhZmUwNGI3NGY0NDA5OWMzZGQwZWI0OTRiZjgwMTYxOWYyNTAyNjI2YTJjZjdkMTZmZCIsImp0aSI6IjFmN2IwODkxLTJkMGUtNDBhZS04MWJiLWQwODVjY2NhOGYyZSIsImlhdCI6MTY2NDI3Njk0NH0.6Q7CPtQIN0uB1ZbVQBj5dshqioop3dJKEpla5DQS5K5qtRPw38SxTEJ1f1DJ_Ka_sgMp_fdh9EEABipTgtgMqg'
And header uniqueid = 'ca38003e-0a8b-47b9-9ac5-4c327c05520f'
And header x-page = 'Home'
When url 'https://jiocinemaqa-api.jio.ril.com/user/v1/watchlist?groups=%5B%5B%22Movie%22%5D%2C%5B%22Show%22%5D%5D'
When method GET
Then status 200
* print response

说明 #

优先选择方式1，Karate的param语法能自动处理所有需编码的特殊字符，既避免手动编码出错，又提升代码可读性。
