嗨，我正试图通过http request.im设置自定义图标，使用https://fcm.googleapis.com/fcm/sendapi并尝试发送通知，我已经成功了，但问题是我无法定义自定义图标。要么它没有显示，要么它显示默认的android图标。此外，如果我能发送base64字符串作为图标，那就太好了。我的代码如下：
{
"to": "dSqZ9U3IA3o:APA91bHR5XRI48k9AUOYR_W3-zxGU1IIffu7amhUtzbaad1ZIoVWrURLDkAZZA49_J_zWKQz7bWbzEckHbOTmonkyNmmRHjxk-mrDw5IDzU9weLF3Wfkghz4RJRQjv8RsSWFUMlHba2w",
"notification" : {
"title": "string",
"body": "string",
"icon": "https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-camera-512.png",
"color": "string",
"sound": "string",
"image": "https://cdn4.iconfinder.com/data/icons/ionicons/512/icon-camera-512.png"
}
}
或
"icon":"data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAABEklEQVQ4T43TPyuHURjG8c+vlMUqm2xIkomMhEGieAPCIn8yKZKUyWIhYZBiUCZeALMMShayGWRRilBKp4560nkez1nPub/3ue7ruivKnQa0oQutqEUfXiol6sdRgzf0YAOXv3X/ARZwjVtMYfFvwyLAGjbxhD1M47MsYBRfOMUYbnCVkpv3g31M4Bu7mEl1D8AUoANNOEAjurGdN+wUYBDVOEEn2ssAQkF97DIU9V6gHy04i3f3eUMcQS8e4/C2ou91mMM7mrGKuywkK2EFh3hI6A2pC+k7KrKxCjsIycueIG0Sy2VsDHoHsJ55HGycxUcZQHiTDdE8zmOck07mBWkJz3jFcdHC5QHC9g3HoRYu7A9AKzMRgaU+zgAAAABJRU5ErkJggg=="
下载png文件并将文件作为notification_icon.png 放置在android/app/src/main/res/drawable中
同时显示
