如何正确使用Flask的jsonify()来返回json? [英] How to correctly use Flask's jsonify() to return json?
问题描述
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 我的代码似乎是返回Response对象,而不是格式化的json对象 其中dict是调用函数返回的字典对象。 / p> 在我的模板中,我有: 显示: 回复135 bytes [200 OK] 我将这个返回json表示,我正在寻找? 您可以使用json.dumps像这样:($) 像这样的模板: 如果这符合您的预期。我认为jsonify用于提供http.response数据,而不是模板的上下文数据。 查看jsonify: https://stackoverflow.com/a/13172658/1307985 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 where dict is a dictionary object returned from calling a function. And in my template, I have: This is displaying: Response 135 bytes [200 OK] How would I make this return the json representation that I am looking for? You can use json.dumps like so: and just format it in the template like so: If this fits to your expectations. I think that jsonify is used to provide http.response data, not context data for templates.

$ b 我有
@ app.route( '/ rparser',methods = ['GET','POST'])
def rparser():
form = ParserForm(request.form)
request.method =='POST ':
result = jsonify(** dict)
return render_template('rparser.html',form = form,result = result)
else:
return render_template('rparser .html',form = form)
)
{%如果结果%}
{{result}}
{%endif%}
$ $ $
$ b $返回render_template(
'index.html',
title ='主页',
result = json.dumps({a:[{o:1},{o:2}]] },sort_keys = False,indent = 2)
)
$ $ p $ code如果结果%$
预先{{结果}} 预>
{%endif%}
@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)
(form up here)
{% if result %}
{{ result }}
{% endif %}
@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)
)
{% if result %}
<pre>{{ result }}</pre>
{% endif %}
