在发送图像之前，请确保将图像转换为Base64，因此：

getBase64(event) {
   let file = event.target.files[0];
   let reader = new FileReader();
   reader.readAsDataURL(file);
   reader.onload = function () {
     console.log(reader.result); // This is the actual result of converting your image to base64
   };
   reader.onerror = function (error) {
     console.log('Error: ', error);
   };
}

以及您的.html
<input type="..." (change)="getBase64($event)">
