【问题描述】：

对 XMLHttpRequest 的访问已被 CORS 策略阻止：对预检请求的响应未通过访问控制检查：请求的资源上不存在“Access-Control-Allow-Origin”标头。

我的 CORS 配置：

[
{
    "AllowedHeaders": [
        "*"
    ],
    "AllowedMethods": [
        "PUT",
        "POST",
        "GET",
        "DELETE"
    ],
    "AllowedOrigins": [
        "*"
    ],
    "ExposeHeaders": [
        "ETag",
        "x-amz-server-side-encryption",
        "x-amz-request-id",
        "x-amz-id-2",
        "Content-Length",
        "Content-Type",
        "Connection",
        "Date",
        "x-amz-version-id",
        "Server"
    ],
    "MaxAgeSeconds": 10
}
]

请求标头：

Accept: */*
Accept-Encoding: gzip, deflate, br
Accept-Language: ru-RU,ru;q=0.9,en-US;q=0.8,en;q=0.7
Access-Control-Request-Headers: authorization,content-type,x-amz-content-sha256,x-amz-date,x-amz-
