倍率接口返回了无效用户倍率

Error message

倍率接口返回了无效用户倍率

What it means

The same validator then checks the optional user_rate_multiplier with the identical finite-and-nonnegative rule. It fires only when the field is present (Some) but carries an invalid value, again guarding rate computations.

Solutions

1. 在 sub2api 后台修正该用户/密钥的自定义倍率为非负有限值
2. 若不需要用户级倍率，删除该字段让 Option 为 None
3. 升级上游修复非法值的序列化问题

Example fix

// before
if let Some(value) = response.user_rate_multiplier {
    if !value.is_finite() || value < 0.0 {
        anyhow::bail!("倍率接口返回了无效用户倍率");
    }
}
// after
if let Some(value) = response.user_rate_multiplier {
    if !value.is_finite() || value < 0.0 {
        tracing::warn!("忽略无效用户倍率: {value}，回退到 effective_rate_multiplier");
    }
}

fn user_multiplier_sane(body: &serde_json::Value) -> bool {
    match body.get("user_rate_multiplier") {
        None | Some(serde_json::Value::Null) => true,
        Some(v) => v.as_f64().map(|x| x.is_finite() && x >= 0.0).unwrap_or(false),
    }
}

match fetch_sub2api_billing_info(&profile).await {
    Err(e) if e.to_string().contains("无效用户倍率") => {
        eprintln!("用户自定义倍率非法：{e}，已跳过，请修正 sub2api 用户倍率配置");
    }
    other => other?,
}

When it happens

Trigger: 上游响应中 user_rate_multiplier 存在但值为 NaN、无穷或负数。

Common situations: 用户在 sub2api 后台手动输入了非法的用户倍率；上游对 null/缺失值的序列化 bug；管理员误配负数倍率。

Understand the failure class

Background: "Must be a positive integer", "Invalid value", "Unsupported": the invalid-argument-value error family, when a library rejects the value you pass — this error's family across 35 libraries.
