我看到这是一篇很老的帖子,但我在尝试将 Google Drive API 与 curl 一起使用时遇到了同样的问题,最后找到了解决方案,但使用起来有点棘手,特别是在内容长度计算方面,所以我会留下回复,以防它帮助别人!
根据 google 文档,首先,您应该在主请求中包含 Content-Type、Content-Length 和 Authorization 标头。对于 Content-Length,你可以让 curl 自动计算它,所以像这样添加其他标题:
-H "Content-Type: multipart/related; boundary=287032381131322"
-H "Authorization: Bearer <Your Oauth2 Access Token>"
其次,您需要在元数据中包含一个多部分部分。这部分需要从边界开始,后面是 Content-Type 头:
--287032381131322
Content-Type: application/json; charset=UTF-8
后面是您的元数据内容:
{\"name\":\"Test\"}
下一部分,是二进制数据的边界开始,它必须再次包含边界分隔符和 Content-Type 标头:
--287032381131322
Content-Type: application/octet-stream
后面是你要上传的二进制数据,简单传递为:
--data-binary @file.ext
最后,您应该包含一个用于关闭边界分隔符的新部分:
--287032381131322--
所以在我的示例中,使用 5679 字节的文件,这将是完整的命令和来自 google 的回复:
curl -v -H "Content-Type: multipart/related; boundary=287032381131322" \
-H "Authorization: Bearer <My Oauth2 Access Token>" \
--data-binary $'--287032381131322\r\nContent-Type: application/json; charset=UTF-8\r\n\r\n{\"name\":\"Test\"}\r\n--287032381131322\r\nContent-Type: application/octet-stream\r\n\r\n' \
--data-binary @b0c11d3b40b71ed08108e5dad7f6ecee-0 \
--data-binary $'\r\n--287032381131322--' \
