本文介绍如何在Python3中利用Requests库发送POST请求。重点讲解如何设置Headers中的Content-Type为application/json，并将字典数据通过json.dumps转换为JSON格式发送。此外，还包含获取响应文本、状态码以及将接口返回数据处理后保存至本地Excel文件的完整示例代码。

Python3发送POST请求的基本设置

直接通过代码示例进行说明。


import requests
import json

raw = {}

在请求头（headers）中增加Content-Type参数，并将其值指定为json格式。

headers = {'Content-Type': 'application/json'}

执行POST请求时，需使用json包将字典形式的参数转换为JSON字符串。

response = requests.post(url='XXXX', headers=headers, data=json.dumps(raw))

查看返回的响应内容。

print(response.text)

查看响应状态码。

print(response.status_code)

接口数据处理与Excel保存示例

补充说明：在Python3中，使用Requests发送POST请求后，对接口返回的数据进行解析处理，最终将结果存入列表并保存至本地Excel文件中。

直接通过代码示例进行说明。
