Http Request Sampler for RESTFul call - uploading multipart/form-data failed -- missing start boundary

[Max Shen]

Trying to use http request sampler to invoke restful svc call and upload a file as multipart/form-data.

Here is the request log

POST [url removed]

POST data:

--EDHfpU--q5a4ZKL4ARKEcJCOmTF8P8b9

Content-Disposition: form-data; name=""; filename="10trxinput.tsv.gz"

Content-Type: multipart/form-data

<actual file content, not shown here>

--EDHfpU--q5a4ZKL4ARKEcJCOmTF8P8b9--

[no cookies]

Request Headers:

Connection: keep-alive

Content-Type: multipart/form-data;charset=UTF-8

Accept-Encoding: gzip,deflate,sdch

Content-Length: 1901

Host: [host removed]

User-Agent: Apache-HttpClient/4.2.3 (java 1.5)

Here is the response

 Missing start boundary

 And I tried the same request and same file in chrome extension Advanced Rest Client and captured the log. I found in the header and the payload, both of them have the same boundary value.

However in the request Jmeter made, the header doesn't have boundary parameter.

Any idea?

Okay.... I changed the Implementation from default to HttpClient3.1, it starts working.....

Issue resolved

how did you post the body content in HTTP Request?  a gxip file would be byte data (I think), and the only I could manage is manipulating the Body Data is via string.  this means the data is corrupted.

Thanks Max Shen for posted your solution. I faced the same problem .. I changed to HttpClient3.1. It started working.

Hi i am using the plupload for uploading the file. when i debug and see in the HttpRequest.Files.count=0 means there is no file.

can u plz tell me how to do that in Jmeter

The "recipe" is the same as for any other JMeter mimicking task:

1. Record your request
2. Perform correlation and parametrisation
3. Replay your request
4. If point 3 isn't successful - compare real request send by browser and the request coming from JMeter with a sniffer tool like Wireshark. Tweak JMeter until requests are absolutely the same (some parameters may differ though, i.e. timestamps, cookies, multipart boundaries, etc.)

Coming back to RESTful Web Service and multipart upload bit, check out Testing REST API File Uploads in JMeter article, it provides comprehensive instructions on how to send "mixed" JSON and multipart requests.
