flask表单提交的两种方式

一.通用方式

通用方式就是使用ajax或者$.post来提交。

前端html

<form method="post" action="/mockservice"  method = "post">
      ... 

    <div class="form-group">
        <label>data <font style="color:#a94442" size="2">
        <input class="form-control" id="data" name="data">
    </div>
    <div class="form-group">
        <button id="start" type="submit" class="btn btn-default">Submit &nbsp</button>
    </div>
</form>

 

将操作绑定

$(document).ready(function() {
   MockTask.start();
});

MockTask ={
    startId: "start_mock",
    start: function(){
        $('#'+this.startId).click(function (){
        ...var data = $('#data').val();

            var form_data = JSON.stringify({
              ..."data": data
            });
            MockSubmit.createTask(form_data);

        });
    },
};

MockSubmit = {
    createTask: function(data){
        var url = "/mockservice";
        $.post(url,data,function(result){
           if (result.code != 'SUCC'){
               alert("failed to create a new api.")
           } else {
               alert("succ");
           }
        });
    }
};

function isEmptyString(info) {
    if (info == null || info == undefined || info.length == 0){
        return true;
    }
    return false
}

这样通过js来实现提交表单的功能,然后flask后端

@app.route("/mockservice",methods=['GET','POST'])
def MockController():
    form = MockCreate()
    if request.method == 'POST':
        code = request.form['code']
        api = request.form['api']
    return ...

通用方式的好处就是在其他框架中也适用。而且也并不复杂。

 

二.比较正宗的flask方式

前端html:

<form method="post" action="/mockservice"  method = "post">
      ... 

    <div class="form-group">
        <label>data <font style="color:#a94442" size="2">
        <input class="form-control" id="data" name="data">
    </div>
    <div class="form-group">
        <button  type="submit" class="btn btn-default">Submit &nbsp</button>
    </div>
</form>

 

前端这时候可以不用绑定操作了,但需要新建一个form对象,用这种方式的好处就是flask有很多内置的方式帮你校验你的提交,一个字:省事!

class MockCreate(Form):
    user_email = StringField("email address",[validators.Email()])
    api = StringField("api",[Required()])
    submit = SubmitField("Submit")
    code = IntegerField("code example: 200",[Required()])
    alias = StringField("alias for api")
    data = TextAreaField("json format",[Required()])

后端这时候就要变成:

@app.route("/mockservice",methods=['GET','POST'])
def MockController():
    form = MockCreate()
    code = form['code']
    api = form['api']
    return render_template("testf.html",api=api,data=code)
