How to invoke web service

[win]

I tried a lot of OCR software and tools, for example, Microsoft's MODI, Google's Tesseract, the recognition effect is not accurate

Later, I found Baidu's online OCR service, the recognition effect is very good, in addition, it can identify 50,000 times a day for free, which is completely enough for individual users.

But I don't know how to call a web service in QM. The format of the web service call is as follows （Sample config files in the attachment）:
