使用 axios get 在 Datatable Vuetify 中获取数据

Question

我想显示来自 get axios api 的数据，当我检查端点时正确调用它 returns 一个包含对象的数组，但在数据表中它说没有数据.

                          this.user = error.data;
                        });
            }
  }
</script>

调用不会显示任何类型的错误，它只是在调用 this.user 时显示“没有数据”，它正确显示了 console.log 中的对象数组.

Return response.data 在 API Axios

[{"sociedade_id":1,"sociedade_name":"Testando","sociedade_cnpj":"","sociedade_status":1,"sociedade_hash":null,"sociedade_data_criacao":"2020-04-14T16:35:14.000Z","sociedade_data_expiracao":null,"solicitante":0,"justificativa":""},{"sociedade_id":2,"sociedade_name":"Sociedade - Teste 2","sociedade_cnpj":"Teste 2","sociedade_status":1,"sociedade_hash":"6de22d12e678b1c03e0cb9f95812aaf36c973404","sociedade_data_criacao":"2020-04-14T16:35:14.000Z","sociedade_data_expiracao":"2020-05-23T23:16:32.000Z","solicitante":0,"justificativa":null}]

连接到数据表的变量不是甜点 this.user 所以不用 This.user=response.data 写 this.desserts=response.data 或者你可以将datatable组件中的变量改成user

<v-data-table :headers="headers" :items="user" :search="search" ></v-data-table>

使用 axios get 在 Datatable Vuetify 中获取数据

get data in Datatable Vuetify with axios get
