java.lang.IllegalArgumentException: Don't know how to encode XXXX as a byte stream

[Marrisa Li]

Hi,

I'm using RestAssured in my test projects, and using similiar below code to send requests, and all get successful responses, but when I tried to upload a .svg file using the post request, it gets below error, can anybody helps to point out the cause please?

Response response = given().contentType(contentType).headers("X-CSRF-Token", ftok).cookies(userCookies).request().body(body).when().post(url);  

Error message: 

java.lang.IllegalArgumentException: Don't know how to encode ------WebKitFormBoundaryLU6DwOyPfQGHAbDG

===============================================

[Marrisa Li]

The contentType and payload info I get from developer tool is as below, so I simulate in the same way in my request,  does RestAssured support the file upload now with content-Type in below format?

Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryLU6DwOyPfQGHAbDG)

[Marrisa Li]

Seems the error is throw from https://github.com/jayway/rest-assured/blob/master/rest-assured/src/main/java/com/jayway/restassured/internal/http/EncoderRegistry.java

in below method:
 public InputStreamEntity encodeStream( Object contentType, Object data ) throws UnsupportedEncodingException {
.....




   else if ( data instanceof byte[] ) {
            byte[] out = ((byte[])data);
            entity = new InputStreamEntity( new ByteArrayInputStream(
                    out), out.length );
        }

I even tried to convert my payload string to byte[] or ByteArrayInputStream, all get the same error
sO it should be failed in new InputStreamEntity( new ByteArrayInputStream(out), out.length );
Anyone can help on this please?

You probably want to send the file as multipart.

Hi Johan,

Thanks a lot for the good suggestion, I took a look at the blog, and tried with multipart, and the response failed with message "http: no such file"

I check the filePath is correctly point to the expected file. do you know where the problem might be please?

with below code:

Response response = given().multiPart("fileuploadcontrol", new File(filePath)).headers("X-CSRF-Token", ftok).cookies(userCookies).when().post(url);

or 

Response response = given().multiPart("fileuploadcontrol", new File(filePath)).contentType("multipart/form-data").headers("X-CSRF-Token", ftok).cookies(userCookies).when().post(url);

Thanks,

Marrisa

[Johan Haleby]

What's the full stacktrace?

[Marrisa Li]

The test code doesn't get exception, the error is that the response doesn't get expected result, the status code is 400, and the response body has the message "http: no such file", so it should be something wrong in server side?

But manually upload the file is good, so I suppose probably there is something wrong with below code to construct the request, any clues please?

Response response = given().multiPart("fileuploadcontrol", new File(filePath)).headers("X-CSRF-Token", ftok).cookies(userCookies).when().post(url);

or 

Response response = given().multiPart("fileuploadcontrol", new File(filePath)).contentType("multipart/form-data").headers("X-CSRF-Token", ftok).cookies(userCookies).when().post(url);

[Marrisa Li]

In developer tools, the request info when I manually upload the request is as below:

Perhaps the control name should be "file" and not "fileuploadcontrol"? Also content-type may have to be set to text/plain?

Hi Joan,

Thanks you very much, it works!

Though in the documentation, and in other google searched webpages, it suggests to used the previous way as I attached above, it failed. Then I tried with your suggestion, it's uploaded successfully, though the uploaded file content is blank which is not as expected currently, I'll try more on this. The bright side is the blocking issue has went away, Thanks a lot!

Thanks,

Marrisa
