Vscode-restclient: Post Request Body: Form data does not seem to pipe the contents of XML file

[wboyle-erwin]

• VSCode Version: 1.14.2
• OS Version: Windows 10 1703 15063.502
• REST Client Version: 0.15.1

Steps to Reproduce:

Using the steps provided by the example
POST http://api.example.com/userupload HTTP/1.1
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file[0]"; filename="sample.xml"
Content-Type: application/xml

< C:\sample.xml
------WebKitFormBoundary7MA4YWxkTrZu0gW--

The actual content of the xml file sent is "< C:\sample.xml". It is not getting evaluated and the contents of the file are not piped in instead.

[Huachao]

@wboyle-erwin I can't reproduce this in my env, and does this file C:\sample.xml really exists in your system? You can verify this by Ctrl+Click the file name in editor, if exists, it will open the file in a new tab

[wboyle-erwin]

sample.xml is just a sample statement. the actual file is different that i am trying to use. however, ctrl + click actually does nothing in my environment. the keybinding does not look to be defined.

[wboyle-erwin]

was able to get ctrl + click enabled by enabling http mode with ctrl k, then m. Currently trying to figure out why it states "Unable to open 'xml file name': resource is not available" even though the location has the file.

[wboyle-erwin]

making a path similar to file:///C:/sample.xml makes the ctrl+click resolve but still doesn't work

[Huachao]

@wboyle-erwin can you test whether escape the \ will work, like C:\\sample.xml or C:/sample.xml

[Huachao]

@wboyle-erwin could you please help to test the work around mentioned above?

[wboyle-erwin]

Here is a post of the REST client snippet I have tried. Clicking the link (file:///) below seems to find the file in question. However, I get "failed to open stream: No such file or directory". Which to me seems like this is not sending any of the contents of the file with the request body.

POST https://dev.myerwin.io/dm/api/erwin-import HTTP/1.1
Authorization: Basic wboyle Testing123
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file[0]"; filename="sample_descriptions.xml"
Content-Type: application/xml

< file:///C:/Users/WilliamBoyle/Documents/sample_descriptions.xml
------WebKitFormBoundary7MA4YWxkTrZu0gW--

I have also tried the following:

< C:/Users/WilliamBoyle/Documents/sample_descriptions.xml
< C:\\Users\\WilliamBoyle\\Documents\\sample_descriptions.xml

Same error as above.

[Huachao]

@wboyle-erwin When you click the link (file:///), can you really open/find the file, in my test (finally on a windows machine), I can't repro your issue(even with no escape), but my code has bug in Ctrl+Click of file links(in non file:/// scheme).

[wboyle-erwin]

with 0.15.2

Clicking the following provides an error now:
< file:///C:/Users/WilliamBoyle/Documents/sample_descriptions.xml

Clicking the following works now:

< C:/Users/WilliamBoyle/Documents/sample_descriptions.xml

The end result of Ctrl + Alt + R is the same unfortunately and doesn't pipe the contents of the file into the request body.

[Huachao]

@wboyle-erwin could you please sent the request to this url https://requestb.in/190tr451, and I will check the actual request you sent to server. Sorry for the incovenience

[wboyle-erwin]

Sure. I sent the request.

[Huachao]

@wboyle-erwin as you can see here, your sent request seems already contains the xml file content in request body.

[wboyle-erwin]

Inspecting the request body, i am not seeing the ending WebKitFormBoundary. Is there a limit to how much is sent?

[Huachao]

Do you mean you inspect your request body on your server side or the site I asked you to request for?

[ozh555]

I had the same problem.

[Huachao]

@ozh555 could you please provide me some details about your OS and sample request, thanks in advance.

[ozh555]

@Huachao
os: windows7 64
vsvode: 1.19.1

REST Client Version: 0.16.2

@ip = http://127.0.0.1:8080

[Huachao]

@ozh555 thanks, could you also temporarily set the request url to https://requestb.in/1lx73751, and trigger a request, so that I can confirm your sent out request. Sorry for the inconvenience.

[Huachao]

@ozh555 as you can see here, sent out request already contains the XML content

[ozh555]

@Huachao
Wow! It's true.
Maybe my server went wrong! But I use Postman can work，I do not know where is wrong。

[Huachao]

@ozh555 it still can be a bug of my code, could you please show me the error response before yo u dig into your server side code?

And another way to verify is that, you also send the request to https://requestb.in/1lx73751 in Postman, so that I can inspect the request difference between postman and mine. Thanks in advance

[Huachao]

@ozh555 except different boundaries, once difference I found is the Content-Type is different, mine is application/json and another is text/xml. So will you server work, if you change your request to text/xml of the file

@ip = http://127.0.0.1:8080

POST {{ip}}/server/app
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="json"

{
"username":"123456"
}
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="1.xml"
Content-Type: text/xml

< D:\123.xml
------WebKitFormBoundary7MA4YWxkTrZu0gW--

[ozh555]

@Huachao
Still can't work.
and vscode had problem:

[Huachao]

@ozh555 so the server didn't respond? Can postman still work now? Sorry for bothering you again and again

[ozh555]

yes, server didn't respond.
postman work all the time.

[Huachao]

@ozh555 it's really strange, I will inspect this later when I have a Windows environment. One last thing, if you change back to application/xml, will the server respond in time? Thanks.

[ozh555]

It's still the same.

[Huachao]

@ozh555 what do you mean __same__ here? Does that mean if we revert to application/xml, the server can respond but not the expected response? Or since you use my extension, the server always don't return(just hang there)?

[ozh555]

server always don't return。
and vscode always waiting。

[Huachao]

@ozh555 what's your server side stack(language + framework)?

[ozh555]

Java-springmvc

[Huachao]

@ozh555 could you please to try again with latest version 0.17.0?

[Huachao]

@wboyle-erwin does this problem still exists in 0.17.0?

[Huachao]

@Platzer could you please to try again with latest version 0.17.0? Can you still repro

[Huachao]

If no one can repro this issue, I'd like to close it now, please feel free to reopen it

[ozh555]

I think this bug has since been fixed.

[newbienewbie]

I'm not sure whether I'm encountering the same bug.

Recently , when I post a file, it waits there , hangs and and never returns . However, if I send a payload in application/json format, this extension works as expected.

For example, I post an image as below:

POST https://eastus.api.cognitive.microsoft.com/face/v1.0/detect?returnFaceLandmarks=true&returnFaceAttributes=age,gender HTTP/1.1
Ocp-Apim-Subscription-Key: xxxx
Content-Type: application/octet-stream

< ./images/celebrities/gutianle-3.jpg

However, the same code worked flawlessly last month. I'm pretty sure there's nothing wrong with the server side.

What I have tired

I've tried to uninstall this extension, remove the folder under ~/.vscode/extensions/humao.rest-client-0.21.1 and re-install the latest version (v0.21.1) , but none of them works.

I'm wondering does this extension write to a temp file? What should I do ?

[Huachao]

@newbienewbie this is a known issue, and already fixed in #332 , and will publish this fix in next release

[newbienewbie]

@Huachao Hi, thanks for your quick response.

Is there a known date when the next version is released ?

[Huachao]

@newbienewbie earlier next week or later this week.

[newbienewbie]

@Huachao Got it . Thanks again for your great extension 💯 !

[Huachao]

@newbienewbie you can try the latest version to verify

[newbienewbie]

@Huachao Sorry for the late response. It works now . Thanks 👍
