我在docker容器中的rails5.2 + webpacker + vuejs中有一个应用程序。
问题在于，在执行 axios.put(this.baseUrl + '.json', obj) 之后，如果不应该重定向或重新设置页面（此处不太确定），则该页面不应该执行。
在代码中，比用单词解释更容易看到。
class PositionsController < ApplicationController
....
def update
respond_to do |format|
if @position.update(position_params)
format.html { redirect_to plan_position_url(@plan, @position), notice: 'Position was successfully updated.' }
format.json { head :no_content } # <--- Here will end the request.
else
format.html { render :edit }
format.json { render json: @position.errors, status: :unprocessable_entity }
end
end
end
....
end
/* eslint no-console: 0 */
import Vue from 'vue/dist/vue.esm';
import axios from 'axios';
...
document.addEventListener('DOMContentLoaded', () => {
axios.defaults.headers.common['X-CSRF-Token'] = document.querySelector('meta[name="csrf-token"]').getAttribute('content')
const app = new Vue({
// ...
computed:{
baseUrl() { return window.location.href },
},
methods: {
autoSave(){
console.log('autoSave')
axios.put(this.baseUrl + '.json', { // <---- Adding .json
position: {
arg1: "yeay!",
}
})
.then(function (response) {
console.log(response);
})
}
},
})
})
....
<a @click.prevent='autoSave' class='btn btn-success btn-lg btn-block'>
<i class="fa fa-magic"></i> Save
</a>
....
vue应用程序没有问题。单击保存按钮后，将发生以下情况：
autoSave position_vue.js:64
Object { data: "", status: 204, statusText: "No Content", headers: {…}, config: {…}, request: XMLHttpRequest } position_vue.js:75 // <-- This is the response of the request, which is ok.
Navega a http://myapp.localhost/plans/1/positions/undefined // <-- this is the weird part ... 'Navega a' means 'Browse to'. This should not be triggered
放置请求（成功）。

我的猜测是，它与webpack-dev-server有关。它尝试以某种方式重新加载页面。
这是我的webpacker / webpacker配置。

我这里的想法不多了。任何帮助都感激不尽。 谢谢
