ios - Stripe STPCustomerDeserializer 无法解析客户 Swift

Question

从 Stripe API 返回的客户 JSON 无法使用 STPCustomerDeserializer(jsonResponse: data) 进行解析，在定位“id”字段时返回 nil。记录数据显示 id 不为零。

客户对象的格式与 Stripe API 返回的格式完全相同。错误消息“来自 Stripe 的响应无法解析为有效的 JSON。”

调试解串器显示它在此处失败:

// required fields
NSString *stripeId = [dict stp_stringForKey:@"id"];
if (!stripeId) {
    return nil; <<< returning here
}

在>>>

- (nullable NSString *)stp_stringForKey:(NSString *)key {
    id value = self[key];
    if (value && [value isKindOfClass:[NSString class]]) {
        return value;
    }
    return nil; << returning here
}

我尝试以不同的格式传递客户数据，但没有成功。

我已经解决了类似的问题，这种情况下的错误似乎是找不到 key 。尝试将模型中的变量设置为可选(？)。如果它没有值，它将返回 nil 或关联的值。

您确定您提到的 id 是 NSString，请尝试使用 NSInteger 或其他数据类型。
