一、获取API-KEY

最近看到阿里DashScope模型服务中有flux-schnell和flux-dev两个文生图模型，FLUX文生图模型在阿里DashScope模型服务灵积首次申请api后可以免费生成1000张图片。

第一步首先要访问DashScope管理控制台：模型服务灵积-总览 (aliyun.com)

然后开通DashScope

然后访问DashScope管理控制台API-KEY管理页面：单击创建新的API-KEY。

二、python调用api

1. 安装DashScope SDK

   pip install dashscope

2. python代码

   from http import HTTPStatus
   from urllib.parse import urlparse, unquote
   from pathlib import PurePosixPath
   import requests
   from dashscope import ImageSynthesis
   import dashscope
   
   dashscope.api_key = 'sk-0000000000000'  # 替换为你的API密钥
   model='flux-dev'
   # model = "flux-schnell"
   prompt = "A beautiful Chinese girl"
   prompt_cn = "一个漂亮的中国女孩"
   
   def sample_block_call(input_prompt):
      rsp = ImageSynthesis.call(model=model,
                                prompt=input_prompt,
                                size='1024*1024')
      if rsp.status_code == HTTPStatus.OK:
          print(rsp.output)
          print(rsp.usage)
          # save file to current directory
          for result in rsp.output.results:
              file_name = PurePosixPath(unquote(urlparse(result.url).path)).parts[-1]
              with open('./%s' % file_name, 'wb+') as f:
                  f.write(requests.get(result.url).content)
      else:
          print('Failed, status_code: %s, code: %s, message: %s' %
                (rsp.status_code, rsp.code, rsp.message))
   
   def sample_async_call(input_prompt):
      rsp = ImageSynthesis.async_call(model=model,
                                      prompt=input_prompt,
                                      size='1024*1024')
      if rsp.status_code == HTTPStatus.OK:
          print(rsp.output)
          print(rsp.usage)
      else:
          print('Failed, status_code: %s, code: %s, message: %s' %
                (rsp.status_code, rsp.code, rsp.message))
      status = ImageSynthesis.fetch(rsp)
      if status.status_code == HTTPStatus.OK:
          print(status.output.task_status)
      else:
          print('Failed, status_code: %s, code: %s, message: %s' %
                (status.status_code, status.code, status.message))
   
      rsp = ImageSynthesis.wait(rsp)
      if rsp.status_code == HTTPStatus.OK:
          print(rsp.output)
      else:
          print('Failed, status_code: %s, code: %s, message: %s' %
                (rsp.status_code, rsp.code, rsp.message))
   
   if __name__ == '__main__':
      sample_block_call(prompt)
      sample_async_call(prompt_cn)

3. 参数说明

4. 模型效果

   下面是上面代码运行后生成的图片,感觉还是可以的。
