如何发送只有一个json字段的分块请求？

import requests

def send_chunked_request(json_data):
    # 将JSON数据转换为字符串
    json_str = json.dumps(json_data)

    # 设置每个块的大小
    chunk_size = 100

    # 分割字符串为多个块
    chunks = [json_str[i:i+chunk_size] for i in range(0, len(json_str), chunk_size)]

    # 发送每个块的请求
    for i, chunk in enumerate(chunks):
        # 创建HTTP请求
        headers = {'Content-Type': 'application/json'}
        data = { 'chunk': chunk }
        response = requests.post('https://example.com/api', headers=headers, json=data)

        # 处理响应
        if response.status_code == 200:
            print(f'Successfully sent chunk {i+1}/{len(chunks)}')
        else:
            print(f'Failed to send chunk {i+1}/{len(chunks)}')

# 示例数据
json_data = { 'field': 'value' }

# 发送分块请求
send_chunked_request(json_data)
