使用flask.jsonify函数从字典输入中输出格式化的json响应时遇到了一些问题,如
I'm having a little trouble using the flask.jsonify function to output a formatted json response from a dictionary input, as described in here.
My code is seems to be returning the Response object, instead of the formatted json object that I want.
I have
@app.route('/rparser', methods=['GET', 'POST'])
def rparser():
form = ParserForm(request.form)
if request.method=='POST':
result = jsonify(**dict)
return render_template('rparser.html', form=form, result=result)
else:
return render_template('rparser.html', form=form)
where dict is a dictionary object returned from calling a function.
And in my template, I have:
(form up here)
{% if result %}
{{ result }}
{% endif %}
This is displaying:
How would I make this return the json representation that I am looking for?
You can use json.dumps like so:
@app.route('/')
def home():
return render_template(
'index.html',
title='Home Page',
result=json.dumps({"a":[{"o":1},{"o":2}]}, sort_keys = False, indent = 2)
)
and just format it in the template like so:
{% if result %}
<pre>{{ result }}</pre>
{% endif %}
If this fits to your expectations. I think that jsonify is used to provide http.response data, not context data for templates.
Have a look here for jsonify: https://stackoverflow.com/a/13172658/1307985
