以下示例说明如何通过 适用于 Python (Boto3) 的 AWS SDK发送 API 请求。如果您尚未将 API 密钥设置为 AWS_BEARER_TOKEN_BEDROCK 环境变量，请在以下代码 $ { api-key} 中将其替换为：

import os
import boto3
# If you already set the API key as an environment variable, you can comment this line out                        
os.environ['AWS_BEARER_TOKEN_BEDROCK'] = "${api-key}"
# Create an Amazon Bedrock client
client = boto3.client(
    service_name="bedrock-runtime",
    region_name="us-east-1" # If you've configured a default region, you can omit this line
# Define the model and message
model_id = "us.anthropic.claude-sonnet-4-6"
messages = [{"role": "user", "content": [{"text": "Hello"}]}]
response = client.converse(
    modelId=model_id,
    messages=messages,
            
HTTP Client (requests package in Python)

                    
先决条件：通过打开终端并运行以下命令来安装 requests 软件包：
                    
python3 -m pip install requests
                    
以下示例说明如何通过 HTTP 客户端直接发送 API 请求。在标题${api-key}中指定。
                    
import requests
url = "https://bedrock-runtime.us-east-1.amazonaws.com/model/us.anthropic.claude-sonnet-4-6/converse"
payload = {
    "messages": [
            "role": "user",
            "content": [{"text": "Hello"}]
headers = {
    "Content-Type": "application/json",
    "Authorization": "Bearer ${api-key}"
response = requests.request("POST", url, json=payload, headers=headers)
print(response.text)
            
HTTP request using cURL

                    
以下示例说明如何使用 cURL 直接发送 API 请求。如果您没有将 API 密钥设置为  AWS_BEARER_TOKEN _BEDROCK 环境变量，则必须将示例$AWS_BEARER_TOKEN_BEDROCK中的密钥替换为密钥的字面值。
                    
curl -X POST "https://bedrock-runtime.us-east-1.amazonaws.com/model/us.anthropic.claude-sonnet-4-6/converse" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AWS_BEARER_TOKEN_BEDROCK" \
  -d '{
    "messages": [
            "role": "user",
            "content": [{"text": "Hello"}]
