ajax代码：

python代码

@web.route('/tpush/pl',methods=['POST'])
def web_tpush():
    cname = request.form['cname']
    cemail = request.form['email']
    curl = request.form['curl']
    #ctext = request.form['ctext']
    print(cname,cemail,curl)
    error = None
    if len(cname) < 2:
        error = '666'
    if len(cemail) < 5:
        error = '777'
    if error is not None:
        return jsonify({'r':1,'error':error})
    return jsonify({'r':0,'rs':ok})

我点击提交后跳转到/tpush/pl
