Uploading files to the server

To upload a file to the server, use a PUT or POST request.

Creating a PUT request

To upload a file using a PUT request, pass the following URI:

http://localhost/flexicapture12/server/MobileApp?filename=[file name]&projectName=[project name]&batchType=[batch name], where:

We recommend that you explicitly specify the value of the Content-type header field. The file to be uploaded is specified in the body of the PUT request.

Hash coding is supported. Pass the value of the MD5 hash function to the FlexiCapture 12 server. The value should be encoded in base64 and passed in the standard  Content-MD5 header. The server will compute the value of the hash function for the file and compare it against the value passed in the header. If the values do not match, the file will be deleted on the server.

There are two possible server responses:

• HTTP 201 (Created) - The file has been successfully uploaded to the server.
• HTTP 400 (Bad request) - Some required parameters have not been specified/The value of the hash function does not match the value specified in the header and no file has been uploaded.

Remarque :Currently, you cannot pass the registration parameters to the server.

Creating a POST request

We recommend using PUT requests. If, for some reason, PUT requests cannot be used, you can upload a file to the server using a POST request. The projectName and batchType parameters can be passed in the URL, just like in a PUT request, or as text fields in the request body.

You can pass multiple images in one POST request. To pass multiple images, set the value of the Content-type field to "multipart/form-data" and specify the value of the separator in the boundary parameter. The names of the files included in a request must not be the same.

Content-type: multipart/form-data; boundary=<random string>
--<boundary value>
Content-Disposition: form-data; name=<field name>; filename=<name of file 1><crlf>
Content-MD5: <value of MD5 hash for file><crlf>
<crlf>
<file data>
          --<boundary value>
Content-Disposition: form-data; name=<field name>; filename=<name of file 2><crlf>
<crlf>
<file data>
        

You can also pass a text field using a POST request.

--<boundary value>
Content-Disposition: form-data; name=”<field name>”<crlf>
<crlf>
<field value><crlf>
        

The request ends with the string

--<boundary value>--<crlf><crlf>
