# 黄金价格查询

实时黄金价格聚合查询，一次返回三大维度：

• 国际贵金属（4 项）：国际金价、国际铂金、国际银价、国际钯金，含最新价 / 涨跌额 / 涨跌幅 / 最高价 / 最低价 / 报价时间

• 国内金价（4 项）：国内金价（黄金延期）、投资金条、黄金回收价格、国内银价

• 品牌金店牌价：内地/香港周大福、周生生、六福珠宝、老凤祥等门店当日牌价

参数 type：all=全部（默认）/ international=国际 / domestic=国内 / brand=品牌金店

国际/国内来自官网实时 jin.js，约 2 分钟缓存；品牌金店来自页面牌价（按日更新）。实时价以接口返回的 update_time / quote_time 为准。

## 5. 请求示例

Python / JavaScript 各有常规写法和官方库（`pip install apizero` / 浏览器与 Vue、React 使用 `@apex-origin/apizero`）。成功后先判断 `code == 0` 再读 `data`。

### cURL

```bash
curl -sS -H "Authorization: Bearer YOUR_API_KEY" "https://v1.apizero.cn/api/gold?type=all"
```

### Python

```python
# 服务端常规写法：标准库 urllib，不用 pip
import json
import ssl
import urllib.error
import urllib.parse
import urllib.request

key = "YOUR_API_KEY"

url = "https://v1.apizero.cn/api/gold"
params = {
    "type": "all",
}
query = urllib.parse.urlencode({k: "" if v is None else str(v) for k, v in params.items()})
req = urllib.request.Request(
    url + ("?" + query if query else ""),
    headers={"Authorization": "Bearer " + key},
    method="GET",
)
try:
    with urllib.request.urlopen(
        req, timeout=20, context=ssl.create_default_context()
    ) as resp:
        raw = resp.read().decode("utf-8")
except urllib.error.HTTPError as e:
    raw = e.read().decode("utf-8", "replace")
body = json.loads(raw)
print(json.dumps(body, ensure_ascii=False, indent=2))
if body.get("code") == 0:
    print(body.get("data"))
```

### Python 官方库

```python
# 官方库（服务端）：先执行一次 pip install apizero
import apizero

key = "YOUR_API_KEY"
client = apizero.key(key)
r = client.gold(
    type="all",
)
if not r.ok:
    raise RuntimeError(r.msg)
print(r.ok, r.code)
print(r.json)
```

### JavaScript

```javascript
// 服务端 Node 18+ fetch
const key = "YOUR_API_KEY";
const url = "https://v1.apizero.cn/api/gold?type=all";
const res = await fetch(url, {
  headers: { Authorization: `Bearer ${key}` },
});
const body = await res.json();
console.log(body);
if (body.code === 0) console.log(body.data);
```

### JavaScript 官方库（Node）

```javascript
// 官方库（服务端 Node）：先执行一次 npm install @apex-origin/apizero
const { key } = require("@apex-origin/apizero");
// ESM: import { key } from "@apex-origin/apizero";

const apiKey = "YOUR_API_KEY";
const client = key(apiKey);
const r = await client.gold({
  "type": "all",
});
if (!r.ok) throw new Error(r.msg);
console.log(r.ok, r.code);
console.log(r.json);
```

### Go

```go
// 服务端常规写法：net/http
package main

import (

## 8. 错误码

先看业务 code。HTTP 也可能不是 200。

| 业务码 | HTTP | 说明 |
| --- | --- | --- |
| 0 | 200 | 成功 |
| 4000 | 400 | 参数错误 |
| 4011 | 401 | API Key 无效 |
| 4013 | 403 | API Key 已暂停 |
| 4014 | 403 | 当前 IP 不在 Key 白名单 |
| 4015 | 401 | 此接口需要 API Key |
| 4022 | 402 | 余额不足 |
| 4029 | 429 | 调用过快（QPS） |
| 4030 | 429 | 今日免费额度已用完 |
| 4040 | 503 | 接口已下线 |
| 4041 | 404 | 接口不存在 |
| 5000 | 500 | 服务器内部错误 |
| 5020 | 502 | 上游暂时不可用 |
| 5021 | 502 | 上游返回格式异常 |

## 9. 变更日志

- **1.0.0** (2026-05-06): 首次上线，聚合国际黄金/国内黄金/十大品牌金店三类金价数据
修复源码 GBK 编码 bug（源码用 <?xml encoding="utf-8" ?> 强制 UTF-8 解析 GBK 内容会导致中文乱码）
缓存改用 Redis（10 分钟），不再依赖文件系统
解析失败容错（三个表都空时返回 5021 而非空 200）
支持 type 参数按需返回单类数据（节省带宽）
