python 发送http请求 api接口 输入一个字符串 返回它的长度

pip install requests

import requests

def get_string_length(input_string):
    api_url = "https://example.com/your/api/endpoint"  # 替换为实际的API地址

    # 构建请求参数
    payload = {"input_string": input_string}

    try:
        # 发送POST请求
        response = requests.post(api_url, data=payload)

        # 检查请求是否成功
        if response.status_code == 200:
            # 解析API返回的JSON数据
            result = response.json()
            length = result.get("length")
            return length

# 要测试的字符串

# 获取字符串长度
