[−][src]Struct async_graphql::types::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
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'
