axios.post使用我的参数自动拼接网址 [英] axios.post automatically splice url with my params

问题描述

我想在前端使用vue和axios实现api:

I want to implement an api with vue and axios in my front-end:

methods:{
  startSpider:function(event){
    alert("spider is ready to run!");

    let data = {'searchKey':this.searchKey,
            'category':this.category,
            'num':this.num};
    axios.post("{% url 'main:getCommodityInfo'%}",
                data,
                {headers:{'X-CSRFToken': this.getCookie('csrftoken')}})
        .then(response=>{
          console.log(response.data)
        })
        .catch(error=>{
          console.log(error);
          alert("connection has error")
        })
  },

当我调用此函数时，我希望从后端获取数据并保留在初始URL.它确实接收到数据，但是网址很快就改变了.

When I call this function, I expect to get data from the back-end and stay at the inital url. It does receive data but the url quickly changed.

经过一番探索，我发现浏览器实现了两个请求！首先是POST，然后是GET:

After some exploration, I find the browser implement two request! First, POST, and next GET:

以'searchKey':'switch'，'category':'electronic'，'num':60 为例.

，我的浏览器网址随后更改为

and My browser url subsequently changes to

为什么会这样?我刚用过POST而不是GET. axios帖子似乎自动将初始URL与params拼接在一起.我尝试了很多方法，但都失败了.甚至我都编写了一个类似的小型演示程序进行测试，但是演示程序运行良好！发生了什么?请帮助我...

Why it happens? I have just used POST not GET. The axios post seems to automatically splice inital url with the params. I have tried a lot of ways but failed. Even I have writed a small demo with the similiar structure like this to test, but the demo runs well! What happened? Help me please...

更新后的我:给我服务器行为(django视图)，并且与我的路由器相关的是path('getCommodityInfo/',views.getCommodityInfo, name = 'getCommodityInfo')

Updated I: Give my server behavior(django-view) and my router related is path('getCommodityInfo/',views.getCommodityInfo, name = 'getCommodityInfo')

def getCommodityInfo(request):
    print(request.body)
    return JsonResponse({"data":True}, safe=False)

更新后的II:给我前端表格:

Updated II: Give my front-end form:

                <form>
                    <label for="searchKey">KeyWords</label>
                    <input v-model="searchKey" placeholder="Input Search Key" type="string" class="form-control" id="searchKey" name="searchKey">

                    <label for="category">Commodity Category</label>
                    <select v-model="selected" id="category" name="category">
                        <option v-for="option in options" v-bind:value="option.value">
                            ${option.text}
                        </option>
                    </select>
                    <br>
                    <label for="num">Amount</label>
                    <input v-model="num" placeholder="Input amount needed" type="string" class="form-control" id="num" name="num" >
                    <button v-on:click="startSpider"  class="btn btn-default">Submit</button>
                    <p>KeyWords : ${ searchKey }</p>
                    <p>Category : ${ selected }</p>
                    <p>Amount: ${ num }</p>
                </form>

推荐答案

由于未设置按钮类型而发生了该错误. 我们可以检查此:

The bug happened because of not setting button type. We could check this:

缺少的默认值是提交按钮"状态.

The missing value default is the Submit Button state.

并且在前端表单中没有按钮的类型，因此按钮类型将是submmit按钮.单击该按钮时，它将自动发送获取请求.

And in the front-end form there is no type for the button, so the button type will be submmit button. When click on the button, it will automatically send a get request.

按如下所示修改按钮:

<button v-on:click="startSpider"  class="btn btn-default" type='button'>Submit</button>
