How to invoke web service
#31
Have you tested it? The base64 value contained in the body is different from the base64 value generated directly by the QM Base64 function.

Macro Macro8
Code:
Copy      Help
str ss.getfile("$desktop$\1.png");; change to file location
_s.encrypt(4 ss "" 2)

str body=
F
;access_token=24.b305c9822131e65eda05e29c157dd719.2592000.1559103982.282335-16139329&image={_s}&language_type=CHN_ENG&probability=true&detect_direction=true

out body
#32
even if that is the case it's not the base64 function its something else
#33
You compare the values ​​of base64 in 1.txt and 2.txt

Macro Macro8
Code:
Copy      Help
str ss.getfile("$desktop$\1.png");; change to file location
_s.encrypt(4 ss "" 2)
_s.setfile("$desktop$\1.txt")

str body=
F
;access_token=24.b305c9822131e65eda05e29c157dd719.2592000.1559103982.282335-16139329&image={_s}&language_type=CHN_ENG&probability=true&detect_direction=true

body.setfile("$desktop$\2.txt")

The value of base64 in 1.txt is correct.
#34
as i said in previous post its something else not the encryption function that is causing it to change.
#35
I don't understand what you are describing, my English is not very good, use Google Translate  Shy

How to solve this problem? Smile
#36
something happens when you add the base64 encoded image to another string. I cannot help . Will need to wait for Gintaras to reply
#37
here you go

Thank you for sharing, Chilkat's json component is free, and it works very well. I saw that the initial value is set. Is this necessary?

I have set it because at times I could get compile error

compile error?  I deleted it and it can run successfully

Sorry at times unknown identifier.

this is first time I used the chilkat component, it feels easier to understand,  Smile
the component is relatively large, 9M size, Shy
thank you again for sharing Heart

It has a lot of stuff in it not just json some u will need a license for. But there is a 30 day free trial to use everything

Running successfully, thanks

I don't understand why this line of code can remove blank lines. Huh
if(!empty(a1[i].Value))
#51
That Statement Basically says if the Variable has a value . (Meaning is not empty or not "")
#52
still a little do not understand, Big Grin can not use the trim function?

Is there an easier way?
use Chilkat's json component code, I can understand, but it is too big  Shy

@Kevin

I just found the problem, if there are Chinese or uincode characters in the picture, QM's base64 encoding is wrong, have garbled characters in the recognition result.

I have prepared a picture 3.png in the attachment

Is there a solution?


This is the result of postman generation, no garbled, it is correct

not sure what that problem is .Don't have the time to look into it either but here is a simplified code for just getting all the words

Code:

IXml x=JsonToXml(r.ResponseText)

Wow, Good code!!

I have not found a better OCR solution at present, I can only use Baidu OCR.

I think it might be what needs to be modified in the unicode code.

Baidu OCR, supports many languages, Support for 50,000 requests per day for free, There are many free features, such as text-to-speech, translation, and image recognition. Smile

- CHN_ENG: mixed in Chinese and English;
- ENG: English;
- POR: Portuguese;
- FRE: French;
- GER: German;
- ITA: Italian;
- SPA: Spanish;
- RUS: Russian;
- JAP: Japanese;
- KOR: Korean
#56
also a better idea instead of using 

_s.replacerx("\+" "%2B")
use instead
_s.escape(9)

it's what its for.. It urlencodes the data. that is what the original problem was the data needed to be urlencoded

wow!  Cool The code is shorter and easier to understand

Improvement is endless   Big Grin

It's a bit strange, why in postman can recognize unicode
#58
cause its probably programmed to just like its programmed to urlencode the image before it sends it
