快速上手

参考官方文档：
https://help.aliyun.com/zh/dashscope/create-a-chat-foundation-model

1、开通DashScope并创建API-KEY

https://dashscope.console.aliyun.com/overview

---

2、安装DashScope SDK

基于 Python 3.8+

pip install dashscope

---

3、API-KEY设置

1）通过环境变量设置

推荐通过环境变量设置api-key

export DASHSCOPE_API_KEY="YOUR_DASHSCOPE_API_KEY"

---

2）通过代码设置

通常不推荐将api-key直接写在代码中

import dashscope
dashscope.api_key="YOUR_DASHSCOPE_API_KEY"

---

3）通过文件设置**

默认会读取~/.dashscope/api_key 作为 DASHSCOPE_API_KEY, 您可以通过环境变量设置api_key保存文件位置。

export DASHSCOPE_API_KEY_FILE_PATH=YOUR_API_KEY_FILE_PATH

代码调用

http 请求示例

curl -X GET 'https://dashscope.aliyuncs.com/api/v1/tasks/73205176-xxxx-xxxx-xxxx-16bd5d902219' \
--header 'Authorization: Bearer <YOUR_API_KEY>'

---

响应示例：

{"request_id": "45ac7f13-xxxx-xxxx-xxxx-e03c35068d83","output": {"task_id": "73205176-xxxx-xxxx-xxxx-16bd5d902219","task_status": "SUCCEEDED","submit_time": "2023-12-20 21:36:31.896","scheduled_time": "2023-12-20 21:36:39.009","end_time": "2023-12-20 21:36:45.913","results": [{"url": "https://dashscope-result-bj.oss-cn-beijing.aliyuncs.com/xxx1.png"},{"url": "https://dashscope-result-bj.oss-cn-beijing.aliyuncs.com/xxx2.png"},{"url": "https://dashscope-result-bj.oss-cn-beijing.aliyuncs.com/xxx3.png"},{"code": "DataInspectionFailed","message": "Output data may contain inappropriate content.",}],"task_metrics": {"TOTAL": 4,"SUCCEEDED": 3,"FAILED": 1}},"usage": {"image_count": 3}
