He probado algunas API de IPFS como cat, ls. Pero no puedo agregar el archivo usando API. Como no existe la documentación adecuada de las llamadas a la API de IPFS.
¿Cómo puedo agregar un archivo en IPFS usando API?
Lea la documentación :
Todos los comandos utilizables desde la cli también están disponibles a través de la API HTTP. Por ejemplo:
compañeros de enjambre de ipfs
Así que para el comando:
USO ipfs add... - Agrega un archivo a ipfs.
ARGUMENTOS
<ruta>...: la ruta a un archivo que se agregará a IPFS.
https://ipfs.io/docs/commands/#ipfs-add
la llamada a la API equivalente sería:
curl -F "image=@/home/bar.jpg" 127.0.0.1:5001/api/v0/add
Si desea utilizar una página web para cargar un documento en ipfs, debería ser algo como
<form action="http://127.0.0.1:5001/api/v0/add">
<input type="file" name="image" accept="image/*">
<input type="submit">
</form>
Agregar una nueva respuesta ya que no está relacionada con la anterior.
Muchas gracias a Vaibhav Saini que me apoyó en GitHub y en el foro de IPFS .
Es relativamente simple, por supuesto, puede simplificar aún más eliminando jQuery, que aquí se usa solo como on change input type filecontrolador:

Código de: https://github.com/cluster-labs/ipfscloud-web#how-to-use
Prueba de que funcionó una vez: https://gateway.ipfs.io/ipfs/QmXhpBNwxEuXuuyKEpYouNvSZw2MqRemtUNSWKbKEiuhBv
Pero no puedo dar fe de ello al 100%.
