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)
