你的问题是如何获取 userId,对吧?
对于获取 userId,可以仿照以下接口的方式,在 mounted 钩子函数中使用 axios 发送 get 请求,获取到后将 userId 赋值给一个变量。具体代码如下:
```
mounted() {
var _this = this;
axios.get('/BookShopSystem_war/getUserId')
.then((response) => {
this.userId = response.data;
var userId = this.userId; // 将userId赋值给一个变量
axios({
method: 'get',
url: 'http://localhost:8080/BookShopSystem_war/getCollectBook/' + userId
}).then(function (result) {
var code = result.data.code;
var data = result.data.data;
if (code == 200) {
_this.collectBook = data;
}
console.log(data)
})
})
.catch((error) => {
console.log(error);
});
},
```
在 delCollect 方法中,可以直接使用 this.userId 获取到 userId,具体代码如下:
```
delCollect(bookId) {
var _this = this;
axios({
method: "delete",
url: "http://localhost:8080/BookShopSystem_war/deleteCollect",
data: {
userId: this.userId, // 直接使用 this.userId 获取到 userId
bookId: bookId
}
}).then(resp => {
alert("取消收藏");
});
}
```
