Recognize text using OCR in RPA

[former_member606336]

Hello everybody,

I want to use OCR to recognize text from a file or image in RPA.

In the added custom task, the Call for OCR Service API was created, but I cannot understand how I can upload the file for this request (ctx.ajax.call).

I want to add it to the "data" parameter.

1.
var model = {
lang: "en, de",
outputType: "txt",
pageSegMode: "1",
modelType: "lstmStandard",
files: "C: .... \ Screenshot_1.png"};


ctx.ajax.call({...
data: model,
...});  

But when I add it to json, I get an error and the OCR service cannot find the “files” parameter.

2.
var form = new FormData ();
  form.append ("files", "/C:....Screenshot_1.png");

ctx.ajax.call({...
data: form,
...});  

When I add it to “FormData” (as in the Doku API from api.sap.com), this is impossible (the error is “ErrorType FormData not defined”).

Kindly help or suggest.

Hi,

To upload a file, you can use the following example :

ctx.ajax.call({
  url: 'https://...',
  method: e.ajax.method.post,
  formData: {
     name: 'files', file: 'C:\\Temp\\Capture.png'
  },
  contentType: e.ajax.content.form,
  success: function(res, status, xhr) {
    sc.endStep(); // Custom
    return;
  },
  error: function(res, status, xhr) {
    ctx.log(' ctx.ajax.call  error: ' + res);
    rootData.MyData.content = res;
  }
});

You will need to adapt it to the service you want to use.
