http - 是否可以通过CoAP传输文件？(Is it possible to transfer a file through CoAP?)

Question

Recently, I am doing a project and I am trying to transfer a json file to the CoAP server.

(最近，我正在做一个项目，我正在尝试将json文件传输到CoAP服务器。)

I put some random values in key:value pairs such as:

(我在key：value对中放置了一些随机值，例如：)

{
    key1: value1,
    key2: [value21, value22, value23]
}

Questions:

(问题：)

• CoAP is pretty much similar to HTTP.

  (CoAP与HTTP非常相似。)

  So, like HTTP, is it possible to transfer a json file through CoAP using POST/PUT method?

  (因此，就像HTTP一样，是否可以使用POST / PUT方法通过CoAP传输json文件？)

  If it is possible, what is the recommended directory location to put the uploaded file into the server ( resource directory)?

  (如果可能，将上传的文件放入服务器的推荐目录位置是什么（ 资源目录）？)

Update:

(更新：)

The actual file size is about to 152.8 kB.

(实际文件大小约为152.8 kB。)

Answer 1

You can transfer arbitary JSON files using CoAP POST/PUT.

(您可以使用CoAP POST / PUT传输任意的JSON文件。)

Which directory would be writable depends fully on the server.

(哪个目录可写完全取决于服务器。)

Note that for a file of that size, transfer times would be considerably longer than with HTTP, as packages are sent in lock-step (putting the first 1kB, response, next 1kB – whereas HTTP has a TCP window).

(请注意，对于该大小的文件，传输时间将比HTTP更长，因为程序包以锁定步骤发送（输入第一个1kB，响应，下一个1kB – HTTP具有TCP窗口）。)
