Firebase

Question

我的产品使用 firebase rtdb、firestore、storage、auth 和 hosting。我没有对我的 CORS 配置进行任何更改。但是，今天我在尝试将图像上传到存储并检索它们时开始收到以下 CORS 错误：

Access to XMLHttpRequest at 'https://firebasestorage.googleapis.com/v0/b/diary-a77f6.appspot.com/o?name=images%2FJ1gU3KPfo1cTHJXhT3iopBqrvVs1%2F-M1Ah4xCQ46GvEZtwgR1%2FBalboa%20Pier%2C%20California%20-%201600x1200%20-%20ID%2027253.jpg' from origin 'https://daybook.app' has been blocked by CORS policy: Request header field x-firebase-gmpid is not allowed by Access-Control-Allow-Headers in preflight response.

我试过了, https://cloud.google.com/storage/docs/configuring-cors, and https://firebase.google.com/docs/storage/web/download-files#cors_configuration 无济于事。

我的主机配置：

{
    "target": "prod",
    "public": "build/production",
    "ignore": [
        "firebase.json",
        "src/firebase/keys.js",
        "**/.*",
        "**/node_modules/**"
    ],
    "rewrites": [
        {
            "source": "**",
            "destination": "/index.html"
        }
    ],
    "headers": [
        {
            "source": "/**",
            "headers": [
                {
                    "key": "Cache-Control",
                    "value": "no-cache, no-store, must-revalidate"
                },
                {
                    "key": "Access-Control-Allow-Headers",
                    "value": "x-firebase-gmpid, Origin, Accept, Content-Type, X-Requested-With, Access-Control-Request-Method,Access-Control-Request-Headers, Authorization"
                }
            ]
        },
        {
            "source": "**/*.@(css|js)",
            "headers": [
                {
                    "key": "Cache-Control",
                    "value": "no-cache, no-store, must-revalidate max-age=0"
                }
            ]
        },
        {
            "source": "**/*.@(eot|otf|ttf|ttc|woff|font.css)",
            "headers": [
                {
                    "key": "Access-Control-Allow-Origin",
                    "value": "*"
                }
            ]
        },
        {
            "source": "**/*.@(jpg|jpeg|gif|png|webp|webp|svg)",
            "headers": [
                {
                    "key": "Cache-Control",
                    "value": "max-age=7200"
                }
            ]
        }
    ]
}

这是我最近在尝试解决问题时添加的内容：

{
    "key": "Access-Control-Allow-Headers",
    "value": "x-firebase-gmpid, Origin, Accept, Content-Type, X-Requested-With, Access-Control-Request-Method,Access-Control-Request-Headers, Authorization"
}

Answer 1

我认为这是 Firestore JS 客户端库的问题。我将其从版本 7.9.2 回滚到版本 7.9.0，错误消失了。

编辑：7.9.3 包含修复。

Firebase - 预检响应中的 Access-Control-Allow-Headers 不允许请求 header 字段 x-firebase-gmpid
