Hi,
I need some help with uploading a document as input document via API as described in the PHP example at this link: http://wiki.processmaker.com/REST_API_C ... t-document

No matter what I'm doing, I keep getting the error: 400, Bad Request: This filename does not exist!.
When looking into the PM classes seems like the $_FILES is always empty. I'm new to APIs, I have no idea how debug further.

Please, let me know if anyone managed to use that piece of code to post an input-document (from another machine).

regards,
/d.

Hi Danmarina ,

I'm also facing same issue.Can you advice me solution ,if you got solution of that issue.
Me also posted on forum Topic How to upload file while creating case using REST API?

Thanks alot in advance

Post your code and maybe someone can help you.

[amosbatto]

In PHP you have to place the @ before the path to avoid this error. See the PHP code example.

[amosbatto]

I found that PHP 5.5 and later has a problem using @ before the path. Instead, you have to use a CurlFile() object. I have updated the documentation. See: http://wiki.processmaker.com/REST_API_C ... t-document

Hi Amosbatto,

I'm using asp.net for saving file and passing path as parameter.
like:-
{
"inp_doc_uid":"test10111124322509756bc1b5test10",
"tas_uid": "24322509756bc1b5012c202012716621",
"app_doc_comment": "test",
"form":"workflow/public_html/test.txt"
}

Response:- "message": "Bad Request: This filename does not exist!"

Can you suggest me ,what's the issue and how to solve? Please.....
Thanks

Mohinish,
Your "form" needs to be a file location on the machine executing the code. Web URLs do not work. If you want to use a web URL, you need to download the file and save it to a local file, which can then be uploaded to REST.

Hi Amosbatto,

Thank You for great Support.

A status code of 302 usually means URL redirection. See: https://en.wikipedia.org/wiki/HTTP_302
I know nothing about asp.net, but this article might help you: http://www.c-sharpcorner.com/UploadFile ... t-web-api/

Hi, I'm facing this problem with .NET too. API always return file does not exist. I would like to know if there is another way to upload the file input

Are you trying to use a web uploader like this or are you trying to run a script which uploads a file which already exists on the computer? Post your code. I don't know anything about .NET, but maybe I can spot something if I look at your code.

You can upload documents by using MultipartFormDataContent in C#. This was all done in ASP.Net Core, but it should work for some of the older .Net MVC versions as well.

Code: Select all

public async Task<ActionResult<JObject>> UploadFile()
{
        using (HttpClient client = new HttpClient())
        using (var formData = new MultipartFormDataContent())
        {
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer",  authToken);

            formData.Add(new StringContent(documentUid), "inp_doc_uid");
            formData.Add(new StringContent(taskUid), "tas_uid");
            formData.Add(new StringContent(documentComment), "app_doc_comment");

            string filePath = Path.GetFullPath("/path/to/file.jpg");
            FileStream fileStream = new FileStream(filePath, FileMode.Open);

            formData.Add(new StreamContent(fileStream), "form", "file.jpg");

            HttpResponseMessage response = await client.PostAsync("https://example.com/api/1.0/workspace/cases/{caseId}/input-document", formData);

            string responseString = await response.Content.ReadAsStringAsync();

            JObject responseJson = JObject.Parse(responseString);

            if (!response.IsSuccessStatusCode)
            {
                return StatusCode((int)response.StatusCode, responseString ?? response.ToString());
            }

            return Ok(responseJson);
        }
}

I also added a REST endpoint for uploading files which you might find useful:
