A simple image upload service with flask implementation

The custom domain name unexpectedly needs the domain name record (excuse me, originally is because the record trouble chooses the foreign country), and wasted my ten dollars,

And I imagine seven cows can be directly in the local can upload pictures, find out, did not find a more appropriate, so spend two days to write a

Use

Since the original intention is that the local script can be published, so there is no front-end interface, and so on later time, plus

Example

Use requests to upload locally

Import requestsdef images ():    url = ' http://127.0.0.1:8000/api/images '    files = {' Images ': open (' desktop.png ', ' RB ')}    multiple_files = [        (' Images ', (' 11.png ', open (' 11.png ', ' RB '), ' image/png ')),        (' Images ', (' Desktop.png ', open (' desktop.png ', ' RB '), ' image/png ')    ]    headers = {        ' api-key ':        ' Inhpewfuzza4mddjbtx4awlppi_oxx1ki8 ',        ' user-agent ': ' mozilla/5.0 (X11; Linux x86_64) applewebkit/537.36 (khtml, like Gecko) chrome/57.0.2987.98 safari/537.36 '    }    # r = Requests.post ( URL, files=multiple_files, headers=headers)    r = requests.post (URL, files=files, headers=headers)    print ( R.text)
