Claude 快速入门

使用 Homebrew 安装 Anthropic CLI：

brew install anthropics/tap/ant

其他安装方法请参阅 CLI 参考中的安装。

使用 Anthropic 账户登录：

ant auth login

这将打开基于浏览器的 OAuth 流程。授权后，确认凭据：

ant auth status

在没有浏览器的远程主机上，传递 --no-browser 获取可在其他设备上打开的 URL，然后将返回的代码粘贴回终端。如果环境中设置了 ANTHROPIC_API_KEY，它将优先于登录凭据。有关 CI 等非交互式环境，请参阅认证。

运行以下命令创建一个简单的网络搜索助手：

ant messages create \
  --model claude-opus-4-7 \
  --max-tokens 1000 \
  --message '{
    role: user,
    content: "What should I search for to find the latest developments in renewable energy?"
  }'

示例输出：

{
  "id": "msg_01HCDu5LRGeP2o7s2xGmxyx8",
  "type": "message",
  "role": "assistant",
  "content": [
    {
      "type": "text",
      "text": "Here are some effective search strategies to find the latest renewable energy developments:\n\n## Search Terms to Use:\n- \"renewable energy news 2024\"\n- \"clean energy breakthrough\"\n- \"solar/wind/battery technology advances\"\n- \"green energy innovations\"\n- \"climate tech developments\"\n- \"energy storage solutions\"\n\n## Best Sources to Check:\n\n**News & Industry Sites:**\n- Renewable Energy World\n- GreenTech Media (now Wood Mackenzie)\n- Energy Storage News\n- CleanTechnica\n- PV Magazine (for solar)\n- WindPower Engineering & Development..."
    }
  ],
  "model": "claude-opus-4-7",
  "stop_reason": "end_turn",
  "usage": {
    "input_tokens": 21,
    "output_tokens": 305
  }
}

从 Claude 控制台 获取 API 密钥，并将其设置为环境变量：

export ANTHROPIC_API_KEY='your-api-key-here'

要在多个 shell 会话中持久保存密钥，请将该行添加到您的 shell 配置文件（如 ~/.zshrc 或 ~/.bashrc）。

安装 Anthropic Python SDK：

pip install anthropic

将以下内容保存为 quickstart.py：

import anthropic

client = anthropic.Anthropic()

message = client.messages.create(
    model="claude-opus-4-7",
    max_tokens=1000,
    messages=[
        {
            "role": "user",
            "content": "What should I search for to find the latest developments in renewable energy?",
        }
    ],
)
print(message.content)

python quickstart.py

示例输出：

从 Claude 控制台 获取 API 密钥，并将其设置为环境变量：

export ANTHROPIC_API_KEY='your-api-key-here'

要在多个 shell 会话中持久保存密钥，请将该行添加到您的 shell 配置文件（如 ~/.zshrc 或 ~/.bashrc）。

安装 Anthropic TypeScript SDK：

npm install @anthropic-ai/sdk

将以下内容保存为 quickstart.ts：

import Anthropic from "@anthropic-ai/sdk";

async function main() {
  const anthropic = new Anthropic();

  const msg = await anthropic.messages.create({
    model: "claude-opus-4-7",
    max_tokens: 1000,
    messages: [
      {
        role: "user",
        content:
          "What should I search for to find the latest developments in renewable energy?"
      }
    ]
  });
  console.log(msg);
}

main().catch(console.error);

npx tsx quickstart.ts

从 Claude 控制台 获取 API 密钥，并将其设置为环境变量：

export ANTHROPIC_API_KEY='your-api-key-here'

要在多个 shell 会话中持久保存密钥，请将该行添加到您的 shell 配置文件（如 ~/.zshrc 或 ~/.bashrc）。

您需要 JDK（25 或更高版本）和 Gradle 或 Maven 在您的 PATH 中。为项目创建目录并包含 Java 源代码目录：

mkdir -p claude-quickstart/src/main/java && cd claude-quickstart

然后添加构建文件。在 Maven Central 上查找当前 SDK 版本。

plugins {
    application
}

repositories {
    mavenCentral()
}

java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(25)
    }
}

dependencies {
    implementation("com.anthropic:anthropic-java:2.33.0")
}

application {
    mainClass = "QuickStart"
}

<project xmlns="http://maven.apache.org/POM/4.0.0">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.example</groupId>
  <artifactId>quickstart</artifactId>
  <version>1.0-SNAPSHOT</version>
  <properties>
    <maven.compiler.release>25</maven.compiler.release>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>
  <dependencies>
    <dependency>
      <groupId>com.anthropic</groupId>
      <artifactId>anthropic-java</artifactId>
      <version>2.33.0</version>
    </dependency>
  </dependencies>
</project>

将以下内容保存为 QuickStart.java，放在项目的 Java 源代码目录中（通常是 src/main/java/）：

import com.anthropic.client.okhttp.AnthropicOkHttpClient;
import com.anthropic.models.messages.Message;
import com.anthropic.models.messages.MessageCreateParams;
import com.anthropic.models.messages.Model;

static void main() {
    var client = AnthropicOkHttpClient.fromEnv();

    var params = MessageCreateParams.builder()
        .model(Model.CLAUDE_OPUS_4_7)
        .maxTokens(1000)
        .addUserMessage(
            "What should I search for to find the latest developments in renewable energy?"
        )
        .build();

    Message message = client.messages().create(params);
    IO.println(message.content());
}

gradle run

mvn compile exec:java -Dexec.mainClass=QuickStart
