如何解决在Laravel中使用vue.js获取动态字段数据
我正在创建多个动态字段，并且将相同的内容发布到laravel控制器方法中，但是我能够获取简单字段数据（不是动态生成的字段），而是动态生成这些值的数组字段，我无法进入控制器方法。
<input :name="'students['+studentdetails.id+']['+studentdetails.class+']'" type="text" class="form-control"/>
<input :name="'students['+studentdetails.id+']['+studentdetails.class+']'" type="text" class="form-control"/>
在获取控制器的方法中：
printr($request->attributes);
export default {
data() {
...
return {
form: new Form({
title: "",attributes: [],}),};
addStudent() {
const header = {
Authorization: "Bearer " + this.token,};
this.form
.post(APP_URL + `/api/addStudent`,{ headers: header })
.then((response) => {
if (response.status == 200) {
location.replace(APP_URL + "/success");
}
});
},};
没有价值。
解决方法
您现在正在将web: gunicorn index:server --workers 4
和Traceback (most recent call last):
File "/app/.heroku/python/lib/python3.6/site-packages/gunicorn/arbiter.py",line 225,in run
handler()
File "/app/.heroku/python/lib/python3.6/site-packages/gunicorn/arbiter.py",line 260,in handle_term
raise StopIteration
StopIteration
During handling of the above exception,another exception occurred:

创建为字符串，但不应创建为字符串。完全删除字符串引号，因为仅使用变量：
