Struct poem::web::Multipart

source ·
pub struct Multipart { /* private fields */ }
Expand description

An extractor that parses multipart/form-data requests commonly used with file uploads.

§Errors

§Example

use poem::{
    error::{BadRequest, Error},
    web::Multipart,
    Result,
};

async fn upload(mut multipart: Multipart) -> Result<()> {
    while let Some(field) = multipart.next_field().await? {
        let data = field.bytes().await.map_err(BadRequest)?;
        println!("{} bytes", data.len());
    }
    Ok(())
}
