下面代码是否有错误的地方给我修改后的代码import argparseimport concurrentfuturesimport requestsdef execute_commandurl command body = xml version=10 encoding=UTF-8 SOAP-ENVEnvelope xmlnsSOAP-ENV=httpschemasxmlsoaporg

下面是修改后的代码：

import argparse
import concurrent.futures
import requests

    body = '''<?xml version="1.0" encoding="UTF-8"?>

我在第27行添加了一个headers参数传递给requests.get()函数，并将headers中的内容设置为与requests.post()函数相同
