Python可以使用`requests`库实现类似Postman的请求工具，以下是一个简单的示例代码，支持GET和POST请求： ```python import requests import json def send_get_request(url, params=None, headers=None): try: response = requests.get(url, params=params, headers=headers) response.raise_for_status() # 检查请求是否成功 return response.json() if response.headers.get('Content-Type') == 'application/json' else response.text except requests.RequestException as e: print(f"请求出错: {e}") return None def send_post_request(url, data=None, json_data=None, headers=None): try: response = requests.post(url, data=data, json=json_data, headers=headers) response.raise_for_status() # 检查请求是否成功 return response.json() if response.headers.get('Content-Type') == 'application/json' else response.text except requests.RequestException as e: print(f"请求出错: {e}") return None # 示例使用 if __name__ == "__main__": # GET请求示例 get_url = "https://httpbin.org/get" get_params = {"key": "value"} get_headers = {"User-Agent": "Python Request Tool"} get_response = send_get_request(get_url, params=get_params, headers=get_headers) print("GET请求响应:") print(get_response) # POST请求示例 post_url = "https://httpbin.org/post" post_data = {"param1": "param1", "pageNum": 2, "pageSize": 5} post_headers = {"Content-Type": "application/json"} post_response = send_post_request(post_url, json_data=post_data, headers=post_headers) print("POST请求响应:") print(post_response) ``` 在上述代码中，定义了`send_get_request`和`send_post_request`两个函数，分别用于发送GET和POST请求。在主程序中，展示了如何调用这两个函数来发送请求并处理响应。
