这篇来看一下如何进行增删改。
删除
使用delete进行删除，一般页面设计的时候也基本都是在列表页进行操作的。首先为删除的链接添加一个函数，因为一般删除都需要传入可定位删除的id或者name，前提是后端api是否支持，查看如下的调用之后，可以看到：
所以，只需要method使用delete，在传入的url中指定id或者name即可。
删除的restful调用：https://docs.konghq.com/0.13.x/admin-api/#delete-api
模版修改
html页面做如下修改
<a nz-tooltip nzTitle="Delete" (click)="handleDeleteFunc()"><i class="anticon anticon-minus-circle-o"></i></a>
添加click处理函数
添加页面定义的click处理函数handleDeleteFunc：
handleDeleteFunc(apiName) {
this._actionInformation = 'Delete';
this.isSpinning = true;
this.modalService.confirm({
nzTitle : '<i>Are you sure to delete this item selected?</i>',
nzContent: '<b>The api selected will be deleted.</b>',
nzOnOk : () => {
this.http.delete('/apis/' + apiName.toString()).subscribe(
item => {
this.isSpinning = false;
this._getApis();
}
);
}
});
}
添加&更新&查看
其他操作诸如添加/更新/查看, 这样基本上get/delete/post/put都进行了使用
