推荐答案

我是Kinvey的工程师.要使用REST API，您首先需要通过向以下位置发出GET请求来获取要上传的API URL:

I'm an engineer at Kinvey. To use the REST API, you need to first get an API URL to upload by making a GET request to:

/blob/:appKey/upload-loc/:fileName

这将返回带有以下对象的响应:

That will return a response with the following object:

{ "URI" : <externalLocation> }

提取response.body.URI，并对该URI执行PUT请求.设置content-length标头，并将您的二进制文件作为request.body传递.

Exctract response.body.URI, and perform a PUT request to that URI. Set the content-length header, and pass your binary file as the request.body.

关于文件上传的一些注意事项:

A couple of notes about file upload:

• upload-loc检索的URI仅有效30秒
• 该库仅支持文件<大小为64 MB.
