[][src]Struct async_graphql::types::Upload

pub struct Upload(_);

Uploaded file

Reference: https://github.com/jaydenseric/graphql-multipart-request-spec

Graphql supports file uploads via multipart/form-data. Enable this feature by accepting an argument of type Upload (single file) or Vec<Upload> (multiple files) in your mutation like in the example blow.

Example

Full Example

use async_graphql::*;

struct MutationRoot;

#[Object]
impl MutationRoot {
    async fn upload(&self, ctx: &Context<'_>, file: Upload) -> bool {
        println!("upload: filename={}", file.value(ctx).unwrap().filename);
        true
    }
}

Example Curl Request

Assuming you have defined your MutationRoot like in the example above, you can now upload a file myFile.txt with the below curl command:

curl 'localhost:8000' \
--form 'operations={
        "query": "mutation ($file: Upload!) { upload(file: $file)  }",
        "variables": { "file": null }}' \
--form 'map={ "0": ["variables.file"] }' \
--form '0=@myFile.txt'
