CLI tool to get data URI of a file.
Duri is written in Rust, so you can install it from crates.io:
console
cargo install duri
Read from file path:
console
duri image.png
Read from standard input:
console
echo image.png | duri -
To see more option, run with --help:
console
duri --help
Assume that you need to upload file to a RESTful HTTP API. The HTTP API may require posted data to be JSON string and the file content to be in form of base64-encoded data URI.
You can combine Duri with jo to build JSON, like:
console
jo -d. file.name=image.png file.content=$(duri image.png)
then pass to a CLI HTTP client, like HTTPie:
console
jo -d. file.name=image.png file.content=$(duri image.png) | http example-api.vn/ekyc/
The duri + jo combo will generate a JSON like
```json { "file": { "name": "image.png", "content": "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAAAAAA6fptVAAABI2..." } }
```
The string is passed to HTTPie via standard input and HTTPie will build a POST request with that JSON data.
Note that, if your HTTP API requires file to be in plain base64 string, not beginning with data:xxx, you don't need Duri.
In that case, just use jo alone, with its % modifier:
console
jo -d. file.name=image.png file.content=%image.png | http example-api.vn/ekyc/
