javascript - 数组项的 Ajax post req 给我一个空响应

Question

正如标题所示，我可以使用 Vue Resource 发送对非数组项的 post 请求，没有任何问题。

当发送数组数据时，响应是空数组。为什么会发生这种情况？

submit:function(){
        var customizedExercises = this.customizedExercises;
        this.$http.post('/api/customized-exercises', customizedExercises).then(function(response){
            console.log(response);
            }, function(response){
            return response;
        })
    },


addSelectbox: function(){
        this.customizedExercises.push({ weight:'',sets_duration:'',name:'',reps:'',exercise_day_id:'' })
        }
    },

数据

customizedExercises : [
{ weight:'',sets_duration:'',name:'',reps:'',exercise_day_id:'' }
],

html

<button type="submit" @click="addSelectbox">add select box</button>
<div v-for=" customizedExercise in customizedExercises" class="input-group">

<span class="input-group-addon">
<select class="selectpicker form-control"  v-model="customizedExercise.name"       name="name" id="name"> 
    <option value="{{ exercise.name }}" v-for="exercise in exercises">{{   exercise.name }}</option>
 </select> 
</span>

<span class="input-group-addon">
<select class="selectpicker form-control"  v-model="customizedExercise.sets_duration"  name="sets_duration" id ="sets_duration"> 
    <option v-for="number in numbers" value="{{number}}">{{number}}</option> 
</select> 
</span>

<span class="input-group-addon">
<select class="selectpicker form-control"  v-model="customizedExercise.weight"   name="weight" id="weight"> 
    <option v-for="number in numbers" value="{{number}}">{{number}}</option> 
</select> 

{{数字}}

<input type="hidden" name="exercise_day_id" v-model="customizedExercise.exercise_day_id" id="exercise_day_id" value="1" />

路线

Route::post('/api/customized-exercises',function() {
$inputs = Request::json()->all();

return $inputs;


});

您需要将对象数组传递到 JSON，然后再将其发送到 PHP。

customizedExercises = JSON.stringify(this.customizedExercises);
