angular - 错误：未捕获（承诺）：HttpErrorResponse: {"headers":{"normalizedNames":[],"statusText":"Bad Request"} 仅在 Safari 浏览器上

问题描述

在 Safari 浏览器上调用 PUT 方法时，Angular 应用程序出现以下错误，但在 Chrome 浏览器上也可以正常工作。

 returnData = await this.http.put(applicationUrl, formattedData).toPromise(); 

[Error] Failed to load resource: the server responded with a status of 503 (Service Unavailable) 
       (pixel, line 0)
