I am creating an application as a test to make a call to a free API available called OCR. OCR requires me to send a image file or a pdf and it converts it to txt, pdf or other text format.
So I have a HTTP Input node that I use to trigger the flow and a File Read node to get the file that I need to send in my request payload.
From reading a few threads on the forum I have made an assumption(maybe wrong on) that I should use MIME to parse the input message. When I do use a MIME parser the message tree does not populate anything for MIME. When I have used xml earlier I see the data in the message tree under XMLNSC, but I am unsure what should be done for PDF's and JPEG's.
I am sure I am doing something wrong could someone please suggest what I should be doing?
Thanks |

update:
I could not figure out how to send a file as an attachment in my request, the API documentation has an option in the Post Paramenter to send the file as base64image. So i read the file from my file input with blob as a input message parser, converted it to base 64 and built my request. But now i get a error after the HTTP request, "414 Request-URI Too Long". See my code below from the compute after the file read.
| Code: |
DECLARE var1 CHARACTER BASE64ENCODE(InputRoot.BLOB.BLOB);
SET OutputLocalEnvironment.Destination.HTTP.RequestURL = 'http://api.ocr.space/parse/image';
SET OutputLocalEnvironment.Destination.HTTP.QueryString.apikey = 'apidummykey';
SET OutputLocalEnvironment.Destination.HTTP.QueryString.language ='ENG';
SET OutputLocalEnvironment.Destination.HTTP.QueryString.isOverlayRequired ='TRUE';
SET OutputLocalEnvironment.Destination.HTTP.QueryString.base64Image=var1; |
In my debug mode i see the local environment overrides but my response header has 414.
| Code: |
HTTPResponseHeader
X-Original-HTTP-Status-Line:CHARACTER:HTTP/1.1 414 Request-URI Too Long
X-Original-HTTP-Status-Code:INTEGER:414
Content-Type:CHARACTER:text/html; charset=us-ascii
Server:CHARACTER:Microsoft-HTTPAPI/2.0
Date:CHARACTER:Tue, 24 Oct 2017 20:36:10 GMT
Connection:CHARACTER:close
Content-Length:CHARACTER:329 |
I am sure that there is something that i am missing or getting wrong. Any help will be appriciated! |

| Are you sending an image in the query string? Not in the message body? |

I find it as odd as my worthy associate that anyone would want a JPG in a query string.
Also interesting is that that URL is on my company's blacklist as an untrustworthy site.

Hmm that's odd, I thought that it is a legit site, but this is just for a POC that I am building for myself.
Just to reconfirm post parameters are sent as a query string correct? |
