Java - Help on POST Multipart file upload.

[Bharath Marrivada]

Hello All,

Following is my Gatling code and POST request body. Getting the "The input message is not readable" response. I have read the documentation, but not sure what is wrong with the request definition.

.bodyParts(
StringBodyPart("name", "content")
.contentType("application/pdf")
.fileName("computerdatabase/ccpupload/Test.pdf")
)

------WebKitFormBoundarypyzZDBVYhFan06by
Content-Disposition: form-data; name="content"; filename="Test.pdf"
Content-Type: application/pdf

Hello,

There's no way to investigate unless you provide an online or portable sample app we can reproduce the issue against.

Hello Stephan,

This is an internal application that can't be accessed outside. If you can help me in constructing the request body as shown below, I will try to run the code in our environment. Also attaching the Fiddler snapshot of the request body.

I am expecting the request body to be as follows.

-----------------------------7334150184050509724267004786

Content-Disposition: form-data; name="content"; filename="Test.pdf"
Content-Type: application/pdf

But in the Gatling, the request body is getting constructed as below, I think it is not correct.

body:MultipartFormDataRequestBody{boundary=[57, 121, 78, 85, 110, 45, 97, 80, 67, 109, 55, 121, 110, 82, 76, 71, 111, 67, 51, 88, 88, 68, 86, 107, 80, 56, 97, 89, 110, 109, 53, 66, 120, 112, 79], contentType='multipart/form-data; boundary=9yNUn-aPCm7ynRLGoC3XXDVkP8aYnm5BxpO', content=Part{name='name', charset=null, transferEncoding='null', contentId='null', dispositionType='null', contentType='application/pdf', customHeaders=, content=[B@53ff6825}

Regards,

Bharath.

You have StringBodyPart wrong.

.bodyParts(
StringBodyPart("name", "content")
.contentType("application/pdf")
.fileName("computerdatabase/ccpupload/Test.pdf")
)

Here:

• "name" is the name of the part
• "content" is the content of the part
• fileName is the value of the filename attribute in the part's Content-Disposition header

You most likely want to use RawFileBodyPart instead.

Hello Stephan,

The following code worked 

.bodyPart(
RawFileBodyPart("content", "computerdatabase/ccpupload/Test.pdf")
.contentType("application/pdf")
.fileName("Test.pdf")
)

I was giving the file path incorrectly, it should be in the RawFileBodyPart and not in the .fileName, also the StringBodyPart instead of  RawFileBodyPart.

Your site documentation is awesome except regarding the file POST method. I suggest adding a few more examples by showing the request body and corresponding Gatling code.

Thank you for your response.

Regards,

Bharath.

Hello Sebastien,

I have accessed the link and tried to edit the page, it says "Fork this project and edit the file". I think my user id (BharathM) needs to be added to the contribution list.

If you can add my user id, I can update the document.

Regards,

Bharath.
