前言

通义千问官网文档地址：https://help.aliyun.com/zh/dashscope/developer-reference/
（通义千问2024.4.26 更新 模型的API-KEY收费，非限时免费开放模型，有使用Token数量的限制） -
支持python 3.8或以上版本
配置流程
1、通义千问API-KEY申请，
官方流程网址指导：https://help.aliyun.com/zh/dashscope/developer-reference/activate-dashscope-and-create-an-api-key
2、安装DashScope SDK
官网教程网址：https://help.aliyun.com/zh/dashscope/developer-reference/install-dashscope-sdk
安装和更新dashscope依赖库
pip install dashscope
pip install dashscope --upgrade
3、API-KEY环境设置
参考官方文档网址：https://help.aliyun.com/zh/dashscope/developer-reference/api-key-settings
- Linux/maxOS
export DASHSCOPE_API_KEY="YOUR_DASHSCOPE_API_KEY"
-
windows 环境变量，新建系统变量（变量：
DASHSCOPE_API_KEY，值：你申请到的API_KEY字符串）
-
或者可以直接在代码调用中全局设置（代码暴露风险）
import dashscope
dashscope.api_key="YOUR_DASHSCOPE_API_KEY"
4、代码实例
示例1：
# 官网示例
from http import HTTPStatus
from dashscope import Generation
def call_with_stream():
user_input = input("请输入：")
messages = list()
msg_dict = [
{'role': 'system', 'content': 'you are a helpful assistant'},
{'role': 'user', 'content': user_input}]
messages.append(msg_dict)
responses = Generation.call(
model="qwen-turbo",
messages=messages,
result_format='message', # 设置输出为'message'格式
stream=True, # 设置输出方式为流式输出
incremental_output=True) # 增量式流式输出
full_content = ""
for response in responses:
if response.status_code == HTTPStatus.OK:
print(response)
full_content += response.output.choices[0].message.content
else:
# 网络请求异常
print('Request id: %s, Status code: %s, error code: %s, error message: %s' % (
response.request_id, response.status_code, response.code, response.message))
print(f"Full content:{full_content}")
if __name__ == '__main__':
call_with_stream()
示例2：
from dashscope import Generation
from dashscope.api_entities.dashscope_response import Role
messages = list()
while True:
message = input('user:')
messages.append({'role': Role.USER, 'content': message})
whole_message = ''
responses = Generation.call(Generation.Models.qwen_max, messages=messages, result_format='message', stream=True,
incremental_output=True)
print('system:', end='')
for response in responses:
whole_message += response.output.choices[0]['message']['content']
print(response.output.choices[0]['message']['content'], end='')
print()
messages.append({'role': 'assistant', 'content': whole_message})
