guys i'm trying to upload a file i understand it is done with submitFormWithBinaryData but how do i set the http method to PUT???

[Michael]

You can call HttpClient.put()

[Yehonatan Levi]

but i need to create the body

[Yehonatan Levi]

i managed to use submitFormWithBinaryData but i have a problem with the url, it’s a long url with token and i think the token is lost in the parsing

[Michael]

I do it like this

[Michael]

suspend fun uploadFile(
        conversationId: Long,
        input: FileInput,
    ): Unit = resources.httpClient.put {
        conversationUrl(conversationId) {
            safePath("files")
        }

        val bytes = input.input.toByteArray()

        val data = formData {
            append("type", input.fileType.name)

            // The name header needs to be present for ktor to recognize it as a file
            append("file", bytes, headersOf(HttpHeaders.ContentDisposition, "filename=upload.file"))
        }

        body = MultiPartFormDataContent(data)
    }

[Michael]

you do not need to use submitFormWithBinary data to set a body

[Yehonatan Levi]

so you wrapped it with MultipartFormDataContent

[Yehonatan Levi]

i did not

[Michael]

It depends on what kind of request youre trying to send

[Yehonatan Levi]

i still get an error about the the request signature

[Yehonatan Levi]

i’m almost sure the query params gets lost

[Yehonatan Levi]

i think it gets stripped when i pass the the url to the put method

[Michael]

I don't know what request you're trying to send and how you're doing that

[Yehonatan Levi]

client.put<HttpResponse>(writeUrl) {
    body =  MultiPartFormDataContent(formData {
        append("image", bitmapFile.readBytes(), Headers.build {
            append(HttpHeaders.ContentType, "image/png")
            append(HttpHeaders.ContentDisposition, "filename=${bitmapFile.name}.png")
        })
    })

[Michael]

that doesn't set headers

[Michael]

Headers.build just builds a Headers object but it doesn't set it

[Yehonatan Levi]

its being passed on…

[Michael]

I don't see the part where you set the request

[Yehonatan Levi]

just up above

[Yehonatan Levi]

i call put with these params

[Yehonatan Levi]

so i’m not sure how to move on from here

[Yehonatan Levi]

since i’ve set everything right

[Yehonatan Levi]

and my technique already worked in okhttp

[Yehonatan Levi]

same with okhttp that worked:

val request = Request.Builder()
        .url(httpUrl)
        .put(bitmapFile.asRequestBody("image/png".toMediaType()))
        .build()
