1. 利用flask的request.form.get()方法
这一中方法主要利用flask的request.form.get方法，获得前端发送给后台的json文件
Python 端代码：
@app.route('/sendjson', methods=['POST']) def sendjson(): # 接受前端发来的数据 data = json.loads(request.form.get('data')) # lesson: "Operation System" # score: 100 lesson = data["lesson"] score = data["score"] # 自己在本地组装成Json格式,用到了flask的jsonify方法 info = dict() info['name'] = "pengshuang" info['lesson'] = lesson info['score'] = score return jsonify(info) JS代码：
<script> $(document).ready(function () { var data = { data: JSON.stringify({"lesson": "Operation System", "score": 100}) } $.ajax({ url:"/sendjson", type: 'POST', data: data, success: function (msg) { alert(msg.name) } }) }); </script> 2. 利用flask的request.get_data()方法
Python端代码：
@app.route('/sendjson2',methods=['POST']) def sendjson2(): # 接收前端发来的数据,转化为Json格式,我个人理解就是Python里面的字典格式 data = json.loads(request.get_data()) # 然后在本地对数据进行处理,再返回给前端 name = data["name"] age = data["age"] location = data["location"] data["time"] = "2016" # Output: {u'age': 23, u'name': u'Peng Shuang', u'location': u'China'} # print data return jsonify(data) 相比第一种方法JS的代码，这一种更常见也更容易理解一些，在前端组织好Json，再传递给后台
JS代码：
<script> $(document).ready(function () { var student = new Object(); student.name = "Peng Shuang"; student.age = 23; student.location = "China"; var data = JSON.stringify(student) $.ajax({ url: "/sendjson2", type: "POST", data: data, success: function (msg) { alert(msg.time) } }) }) </script>
