How can i send a multipart(file) to TestRequest?

[lpf763827726]

i try many way, but they are not success, i try to use set_payload, still no good, i need an example please

let req = test::TestRequest::post()
            .uri("/api/v1/image/avatar")
            .header("Authorization", format!("Bearer {}", token))
            .set_payload(&buf) // try multipart to bytes
            .to_request();

the client doesn't have a way to construt multipart requests yet

in the tests for actix-multipart we use a helper function like this: https://github.com/actix/actix-web/blob/HEAD/actix-multipart/src/server.rs#L963

thanks for feedback, actually i want to test send to the API, but i can't see any way about TestRequest in #L1014, look like only test the multipart, not the api request

Is this still not possible?

I'm hoping to test this as well. Is this still not possible?

It seems the testing API still doesn't provide any facility for Multipart file uploads as of version 4.4.0.

I've added the following function to my test helper module:

pub fn build_multipart_payload_and_header(file_name: &str, file_contents: &str) -> (String, (HeaderName, HeaderValue)) {
    let boundary = "-----------------------------202022185716362916172375148227";
    let payload = format!("{boundary}\r\n\
Content-Disposition: form-data; name=\"file\"; filename=\"{file_name}\"\r\n\
Content-Type: text/csv\r\n\
\r\n\r\n\
{file_contents}\r\n\r\n\
{boundary}--");
    let header = (
        actix_web::http::header::CONTENT_TYPE,
        HeaderValue::from_static("multipart/form-data; boundary=---------------------------202022185716362916172375148227"),
    );
    (payload, header)
}

and use it with:

        let file_name = "upload.json";
        let file_contents = include_str!("../resources/files/upload.json");
        let (payload, content_type_header) = build_multipart_payload_and_header(file_name, file_contents);

        let req = test::TestRequest::post()
            .uri("/YOUR_SERVICE")
            .set_payload(payload.clone())
            .insert_header(content_type_header)
            .to_request();

        let resp = test::call_service(&mut app, req).await;
