又拍云的表单 API 不支持通过 ajax 跨域调用吗？

[dog]

用 ajax 上传文件，返回 400 错误，提示：

Access to XMLHttpRequest at 'https://v0.api.upyun.com/xxx' from origin 'https://xxxxx' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

难道这个接口只能用 HTML 的 form 提交？不能 ajax 调用？

用服务端调

应该是支持的哦。需要检查一下你的代码和浏览器环境呢。
