如何使用curl上传一个图像文件"Content-Type:multipart/related"

Question

curl --trace trace.txt -X POST -H'Content-Type:multipart/related; boundary = boundary_1234' - data-binary $' - boundary_1234\r \nContent-Type:application/json; charset = UTF-8\r \n\r \n {\ r \n\t"title":"TestFile"\ r \n}\r \n\r \n - boundary_1234\r \nContent-Type: image/jpeg\r \n\r \n' - 数据二进制'@ Image0177.jpg' - 数据二进制$'\ r \n - boundary_1234 - \r \n''localhost:3000/google /上传/驱动器/ V2 /文件？uploadType =多

它没有成功,image0177.jpg大小17k,但上传谷歌驱动器6bit,为什么？

Answer 1

我认为这是一个相当古老的帖子,但是我只是遇到了同样的问题,尝试使用带有curl的Google Drive API并最终找到了解决方案,但使用起来有点棘手,特别是在内容长度计算上,所以我会留下回复万一它可以帮助别人!

根据谷歌文档,首先,您应该在主要请求中包含Content-Type,Content-Length和Authorization标头.对于Content-Length,你可以让curl自动计算它,所以添加其他标题如下:

-H "Content-Type: multipart/related; boundary=287032381131322"
-H "Authorization: Bearer <Your Oauth2 Access Token>"

其次,您需要包含带有元数据的多部分.此部分需要从边界开始,然后是Content-Type标头:

--287032381131322
Content-Type: application/json; charset=UTF-8

其次是您的元数据内容:

{\"name\":\"Test\"}

下一节是二进制数据的边界开始,它必须再次包含边界定界符和Content-Type标头:

--287032381131322
Content-Type: application/octet-stream

接下来是您要上传的二进制数据,它简单地传递为:

--data-binary @file.ext

最后,您应该包含一个用于关闭边界定界符的新部分:

--287032381131322--

所以在我的例子中,使用5679字节的文件,这将是完整的命令和谷歌的回复:

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--'                                \
