如何将上个接口的返回token，传给下个接口当做请求参数? 这是最常见的一个问题了。
解决这个问题其实很简单，我们只需取出token值，设置为一个中间变量a，下个接口传这个变量a就可以了。那么接下来就是解决两个问题：
环境： httprunner==3.1.4
我现在有一个登陆接口A,登陆成功后返回一个token值。有一个获取绑定卡号的接口B，但是接口B必须要先登录后传登录的token才能访问
A接口登录接口文档基本信息
B接口获取绑定卡号的接口文档基本信息
先不带token去访问接口B，使用命令行工具httpie测试接口
C:\Users\dell>http http://127.0.0.1:8000/api/v1/userinfo/
HTTP/1.1 401 Unauthorized
Allow: GET, POST, HEAD, OPTIONS
Content-Length: 58
Content-Type: application/json

Vary: Accept
WWW-Authenticate: Token
X-Frame-Options: SAMEORIGIN
{
"detail": "Authentication credentials were not provided."
}
不带token会提示没权限访问：401 Unauthorized
先使用接口测试工具测试下，用postman,或者fiddler都可以，我这里为了查看报文信息方便，用httpie命令行工具
先访问接口A获取token值234af73571da46ade79ea6a74961b1d23d609b79
D:\>http http://127.0.0.1:8000/api/v1/login/ username=test password=123456 -v

}

"msg": "login success!",
"token": "234af73571da46ade79ea6a74961b1d23d609b79",
"username": "test"
}
传给下个接口B
D:\>http http://127.0.0.1:8000/api/v1/userinfo/ Authorization:"Token b7e02c959fbae4c2a0d9094f6f9b9a35fa8aaa1e" -v

"name":"test",
"sex":"F",
"age":24,
"mail":"xxx@qq.com",
"create_time":"2020-06-12"
}]
}
传头部参数用xx:xxxx格式，中间用冒号:，如：User-Agent:demo-agent/1.0 ‘Cookie:a=b;b=c‘ ,由于Authorization参数中间有空格，用双引号包起来
提取登录接口返回的 token 值，使用 extract 提取器
extract:
token: content.token # 提取token
在 config 中使用 export 关键字导出变量，设置为全局变量，方便后面的步骤调用
config:
name: logincase
variables: {}
export:
- token
下个接口的用例引用token参数使用$token,完整的用例userinfo.yml如下
# 作者-上海悠悠 QQ交流群:717225969

config:
name: logincase
base_url: http://127.0.0.1:8000
variables: {}
export:
- token
teststeps:
-
name: step1 login
request:
url: /api/v1/login/
method: POST
headers:
Content-Type: application/json
User-Agent: python-requests/2.18.4
json:
username: test
password: 123456
extract:
token: content.token # 提取token
validate:
- eq: [status_code, 200]
- eq: [headers.Content-Type, application/json]
- eq: [content.msg, login success!]
- eq: [content.code, 0]
-
name: step2 get user info
request:
url: /api/v1/userinfo/
method: GET
headers:
Content-Type: application/json
User-Agent: python-requests/2.18.4
Authorization: Token $token # 引用token
validate:
- eq: [status_code, 200]
- eq: [headers.Content-Type, application/json]
- eq: [content.code, 0]
- eq: [content.data.0.mail, 283340479@qq.com]
config 中 export 导出，主要是为了关联做准备。导出的变量，主要是用于Step之间参数的传递。
如果导出多个变量，格式如下：
.export(*["token", "var1", "var2"]
userinfo_test.py 对应的代码如下
