flask fetch post data code example

Example 1: get post request data flask

@app.route('/form-example', methods=['GET', 'POST']) #allow both GET and POST requests
def form_example():
    if request.method == 'POST':  #this block is only entered when the form is submitted
        language = request.form.get('language')
        framework = request.form['framework']

        return '''<h1>The language value is: {}</h1>
                  <h1>The framework value is: {}</h1>'''.format(language, framework)

    return '''<form method="POST">
                  Language: <input type="text" name="language"><br>
                  Framework: <input type="text" name="framework"><br>
                  <input type="submit" value="Submit"><br>
              </form>'''

Example 2: get request body flask

request.args: the key/value pairs in the URL query string
request.form: the key/value pairs in the body, from a HTML post form, or JavaScript request that isn't JSON encoded
request.files: the files in the body, which Flask keeps separate from form. HTML forms must use enctype=multipart/form-data or files will not be uploaded.
request.values: combined args and form, preferring args if keys overlap
request.json: parsed JSON data. The request must have the application/json content type, or use request.get_json(force=True) to ignore the content type.
