[−][src]Struct async_graphql::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::Upload; struct MutationRoot; #[async_graphql::Object] impl MutationRoot { async fn upload(&self, file: Upload) -> bool { println!("upload: filename={}", file.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'
Fields
filename: String
Filename
content_type: Option<String>
Content type, such as application/json
, image/jpg
...
path: PathBuf
Temporary file path
