角度单元渲染器在init中不获取IcellRenderParams

我正在尝试制作一个单元渲染器,用于使用Angular将IP地址转换为可点击的SSH链接。渲染器组件:

import { Component, OnInit, OnDestroy } from "@angular/core";
import { DomSanitizer, SafeUrl } from "@angular/platform-browser";

import { ICellRendererAngularComp } from "ag-grid-angular";
import { ICellRendererParams } from "ag-grid-community";

const username = "me";

/**
 * SSHCellRendererComponent is an AG-Grid cell renderer that provides ssh:// links as content.
 */
@Component({
    selector: "ssh-cell-renderer",
    styleUrls: ["./ssh-cell-renderer.component.scss"],
    templateUrl: "./ssh-cell-renderer.component.html"
})
export class SSHCellRendererComponent implements ICellRendererAngularComp {

    /** The IP address or hostname to which the SSH link will point. */
    public get value(): string {
        return this.val;
    }
    private val = "";

    /** The SSH URL to use. */
    public get href(): SafeUrl {
        const url = `ssh://${username}@${this.value}`;
        return this.sanitizer.bypassSecurityTrustUrl(url);
    }

    constructor(private readonly sanitizer: DomSanitizer) {}

    /** Called by the AG-Grid API at initalization */

    public refresh(params: ICellRendererParams): boolean {
        this.val = params.value;
        return true;
    }

    /** called after ag-grid is initalized */
    public agInit(params: ICellRendererParams): void {
        console.log("has value?:", Object.prototype.hasOwnProperty.call(params, "value"));
        console.log("getval:", params.getValue());
        this.val = params.value;
    }
}

然后模板看起来像:

<a [href]="href" target="_blank">{{value}}</a>

这应该是非常基本的,我在AngularJS中基本上就是这么做的,但它不起作用。这些单元格最后都会显示如下内容:

<a href="ssh://me@" target="_blank"></a>

那两个呢 console.log 我有 agInit 告诉我原因:

16:34:38.554     has value?: false             ssh-cell-renderer.component.ts:62:10
16:34:38.555     getval: undefined             ssh-cell-renderer.component.ts:63:10

我不知道他们给了什么样的东西 阿吉尼特 (而且可能 refresh 但显然不是 ICellRendererParams -及 getValue 也帮不了我,因为不管出于什么原因,它总是会回来 undefined 1.我有权访问 data (从中我可以看出,所呈现的价值实际上不是 未定义 ),但如果我想使用“IPv4地址”列和“IPv6地址”列为SSH链接制作一个呈现程序,我需要两个几乎相同的组件,这是大量重复的代码。

那么我错过了什么?
