在 python 中使用 swagger codegen 客户端将 header 添加到 api 调用的细节尚不清楚

The specifics of adding a header to an api call with a swagger codegen client in python are unclear

指出正确的文档、教程、示例或提供一个,展示如何将特定的身份验证令牌添加到 [=49= 中 Swagger 生成的 API 客户端中的特定 header ]?

这是我试过的方法:
使用正确的 curl 命令,我的 API 调用工作正常:

curl -v -H 'X-CAG-Authorization: AG_CONSUMER_TOKEN access-key=31337-70k3n' \
     'https://api.company.net/api/v1/user/detail?user=1'

* Connected to api.company.net (10.10.1.10) port 443 (#0)
* TLS 1.2 connection using TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384

但是,当我在我的 Python (2.7.12) 客户端中尝试相同的基本请求时,我得到了授权失败,尽管确认令牌已进入 header 即将成为用过的。有关正确使用客户端的更多详细信息或有关如何获取确切请求和响应的更多详细信息的更多详细信息,我们将不胜感激。

swagger-codegen 是 http://editor.swagger.io/ 的 运行,我按照 api 示例尝试添加额外的 header:api_example.py

from __future__ import print_function
import time
import swagger_client
from swagger_client import ApiClient
from swagger_client import Configuration
from swagger_client.rest import ApiException
from pprint import pprint

# Setup the authentication token header
conf = Configuration()
conf.api_key_prefix = {"teamname": "AG_CONSUMER_TOKEN"}
conf.api_key = {
    "teamname": "access-key=31337-70k3n"
}
conf.api_client = ApiClient(None, "X-CAG-Authorization",
                            conf.get_api_key_with_prefix("teamname"))

# create an instance of the API class
api_instance = swagger_client.SupplierApi()
user = 1
try:
    api_response = api_instance.get_api_v1_user_details(user)
    pprint(api_response)
except ApiException as e:
    print("Exception when calling "
          "SupplierApi->get_api_v1_user_details: %s\n" % e)

通过将 print(self.api_client.default_headers) 放入 supplier_api.py,我可以看到 header 似乎已设置。

{'X-CAG-Authorization': 'AG_CONSUMER_TOKEN access-key=31337-70k3n', 'User-Agent': 'Swagger-Codegen/1.0.0/python'}

所以我又应该在我的示例中更改什么才能让它传递 header 并完全按照简单的 curl 调用的方式获得授权?

更新 我也试过定义它:

      security:
      - api_key: []
securityDefinitions:
  api_key:
    type: "apiKey"
    name: "X-CAG-Authorization"
    in: "header"

然后只设置密钥:

swagger_client.configuration.api_key['X-CAG-Authorization'] = \
    'access-key=31337-70k3n'
swagger_client.configuration.api_key_prefix['X-CAG-Authorization'] = \
    'AG_CONSUMER_TOKEN'

但是除了 header 从我正在打印的默认 header 中消失之外,这并没有太大变化。

我已经尝试了您的代码示例,看起来您的 headers 实际上已传递到服务器。

您可以通过将 print headers 添加到 swagger_client/rest.py 文件来确认这一点,在此之前:

r = self.pool_manager.request(method, url,
                              fields=query_params,
                              preload_content=_preload_content,
                              timeout=timeout,
                              headers=headers)

你确定服务器端没有问题吗?也许有些 headers 破坏了身份验证?

下面的 curl 命令是否也有效?

curl -v \
 -H 'X-CAG-Authorization: AG_CONSUMER_TOKEN access-key=31337-70k3n' \
 -H 'Content-Type: application/json' \
 -H 'Accept: application/json;charset=utf-8' \
 -H 'User-Agent: Swagger-Codegen/1.0.0/python' \
 'https://api.company.net/api/v1/user/detail?user=1'

因为这应该给你返回 swagger 的完全相同的答案,即 401 错误。如果是这样,您可以从服务器端进行调试。如果没有,我不知道。

在您的规范中,您需要描述安全设置(在您的案例中是 API 密钥),类似于 [=23 的 securityDefinitions 部分中定义的 example =]规格

然后在端点中,您将需要"apply"类似于此的安全定义example

之后,您可以在auto-generated Python API客户端的configuration.py中设置API键,HTTP请求将包含API 相应的密钥(在规范的安全设置中定义的 header 或 URL 查询字符串中)

自从上次稳定发布 Swagger Codegen 以来,auto-generated Python API 客户端有了很多增强功能,所以我建议您使用最新的 master并在本地构建 JAR 以生成 API 个客户端。
