【问题标题】：How to perform a multipart upload with Google Drive REST API v3如何使用 Google Drive REST API v3 执行分段上传
【发布时间】：2021-02-10 08:43:05
【问题描述】：

我正在尝试按照指南 https://developers.google.com/drive/api/v3/manage-uploads#multipart 发出 https 请求以上传文件。这是我尝试发送的内容：

POST https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart&key=AIz...Q4 HTTP/1.1\r\n
Authorization: Bearer ya...8A\r\n
Content-Type: multipart/related; boundary=foo_bar_baz\r\n
Content-Length: 150\r\n
\r\n
--foo_bar_baz\n
Content-Type: application/json; charset=UTF-8\n
\n
{\n
    "title": "My File.jpg"\n
}\n
\n
--foo_bar_baz\n
Content-Type: text/txt\n
\n
JPEG data\n
--foo_bar_baz--\r\n

你能告诉我我错了什么或一个可行的例子吗？谢谢

更新：

好的，经过几次尝试我都能找到正确的https请求，例如：

POST https://www.googleapis.com/upload/drive/v3/files?uploadType=multipart&key=AI...qeQ4 HTTP/1.1\r\n
Authorization: Bearer yaSN...Q9Q\r\n
Content-Type: multipart/related; boundary=foo_bar_baz\r\n
Content-Length: 167\r\n
\r\n
--foo_bar_baz\n
Content-Type: application/json; charset=UTF-8\n
\n
{\n
    "name": "My File.txt"\n
}\n
--foo_bar_baz\n
Content-Type: text/plain; charset=UTF-8\n
\n
aaaaa\n
--foo_bar_baz--

我需要设置正确的body长度，否则服务器会返回错误。
