为啥 httprunnner 运行 YML 文件的时候，request 请求会自动往最后面加一个/，导致变成了/basic-api/s1/user/login/，导致我请求不同

我的测试 YML 文件：
config:
name: "登录测试"
variables:
loginurl: http://123.139.118.95:7001/basic-api/s1/user/login
verify: False

teststeps:

• name: 测试登录用例 request: method: POST url: $loginurl json: userNo: "123" userPassword: "456"

打印：
-------------------- request --------------------
POST /basic-api/s1/user/login/ HTTP/1.1
Host: 123.139.118.95:7001
Content-Type: application/json; charset=utf-8

{"userNo":"123","userPassword":"456"}

{"msg":"token 为空","code":401}
