鉴权与通用约定

Bash / macOS / Linux；Windows 可使用 Git Bash。

# 先按“鉴权与通用约定”设置环境变量
: "${MASS_API_KEY:?请先设置 MASS_API_KEY}"
MASS_BASE_URL="${MASS_BASE_URL:-https://api.vizen.cc}"

curl --silent --show-error --fail-with-body --max-time 120 \
  -X GET "${MASS_BASE_URL%/}/v1/products" \
  -H "Authorization: Bearer $MASS_API_KEY"

Python 3.10+，仅使用标准库。保存为 example.py，运行 python example.py。

import json
import os
import urllib.error
import urllib.parse
import urllib.request

base_url = os.environ.get("MASS_BASE_URL", "https://api.vizen.cc").rstrip("/")
api_key = os.environ["MASS_API_KEY"]
path = "/v1/products"
headers = {"Authorization": "Bearer " + api_key}
body = None
request = urllib.request.Request(
    base_url + path, data=body, headers=headers, method="GET"
)
try:
    with urllib.request.urlopen(request, timeout=120) as response:
        result = json.load(response)
        print(json.dumps(result, ensure_ascii=False, indent=2))
except urllib.error.HTTPError as error:
    print("HTTP", error.code, error.read().decode("utf-8"))
    raise SystemExit(1)
except urllib.error.URLError as error:
    # 创建请求出现网络异常时，保留原幂等键；不要生成新键后盲目重试。
    print("请求未能确认:", error.reason)
    raise SystemExit(1)

JDK 17+，仅使用标准库。保存为 UTF-8 的 Example.java；执行 javac -encoding UTF-8 Example.java，再执行 java Example。

import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.nio.charset.StandardCharsets;
import java.time.Duration;

public class Example {
    static String requireEnv(String name) {
        String value = System.getenv(name);
        if (value == null || value.isBlank()) {
            throw new IllegalArgumentException("请设置环境变量 " + name);
        }
        return value;
    }

    public static void main(String[] args) throws Exception {
        String base = System.getenv().getOrDefault("MASS_BASE_URL", "https://api.vizen.cc");
        base = base.replaceAll("/+$", "");
        String path = "/v1/products";
        HttpRequest request = HttpRequest.newBuilder(URI.create(base + path))
            .timeout(Duration.ofSeconds(120))
            .header("Authorization", "Bearer " + requireEnv("MASS_API_KEY"))
            .method("GET", HttpRequest.BodyPublishers.noBody())
            .build();
        HttpClient client = HttpClient.newBuilder().connectTimeout(Duration.ofSeconds(20)).build();
        // 网络异常会抛出异常；重试创建请求时保留相同幂等键和参数。
        HttpResponse<String> response = client.send(request,
            HttpResponse.BodyHandlers.ofString(StandardCharsets.UTF_8));
        System.out.println(response.body());
        if (response.statusCode() >= 400) {
            throw new IllegalStateException("HTTP " + response.statusCode());
        }
    }
}

Go 1.20+，仅使用标准库。保存为 main.go，运行 go run main.go。

package main

import (
    "fmt"
    "io"
    "net/http"
    "os"
    "strings"
    "time"
)

    value := os.Getenv(name)
    if value == "" { panic("请设置环境变量 " + name) }
    return value
}

func main() {
    base := os.Getenv("MASS_BASE_URL")
    if base == "" { base = "https://api.vizen.cc" }
    base = strings.TrimRight(base, "/")
    path := "/v1/products"
    req, err := http.NewRequest("GET", base + path, nil)
    if err != nil { panic(err) }
    req.Header.Set("Authorization", "Bearer " + requireEnv("MASS_API_KEY"))
    client := &http.Client{Timeout: 120 * time.Second}
    resp, err := client.Do(req)
    // 网络异常不代表创建失败；重试时保留原幂等键和参数。
    if err != nil { panic(err) }
    defer resp.Body.Close()
    data, err := io.ReadAll(resp.Body)
    if err != nil { panic(err) }
    fmt.Println(string(data))
    if resp.StatusCode >= 400 { panic(fmt.Sprintf("HTTP %d", resp.StatusCode)) }
}
