使用 Python 执行 Curl 命令(demo)

参考链接：https://blog.csdn.net/weixin_43420032/article/details/84646041

示例 1

Curl命令：

curl --request POST --url https://open.workec.com/auth/accesstoken --header 'cache-control: no-cache' --header 'content-type: application/json' --data '{ "appId": appId, "appSecret": "appSecret"}'

Python实现上述命令：

import requests   # requests模块需要使用 pip 命令安装

headers = {
    'cache-control': 'no-cache',
    'content-type': 'application/json',
}

data = '{	"appId": appId,	"appSecret": "appSecret"}'
response = requests.post('https://open.workec.com/auth/accesstoken', headers=headers, data=data)

示例 2

Curl命令：

curl -X POST --data '{"jsonrpc":"2.0","method":"cfx_getNextNonce","params":["0x1c13f30fa2b59d76191325b4a80032558c1b3b73"],"id":1}' -H "Content-Type: application/json" http://39.107.127.68:12537

Python实现上述命令：

import requests
import json

headers = {
    'content-type': 'application/json',
}

url = 'http://39.107.127.68:12537'

data = '{"jsonrpc":"2.0","method":"cfx_getNextNonce","params":["0x1c13f30fa2b59d76191325b4a80032558c1b3b73"],"id":1}'

response = requests.post(url, headers=headers, data=data2)
print(response)
print(response.content)
print(type(int(json.loads(response.content)["result"])))   # 取出响应内容中 "result" 字段的值
print(int(json.loads(response.content)["result"], 16))   # 16 进制字符串转成整型 int
print(type(int(json.loads(response.content)["result"], 16)))

### 注：
### 在 Linux 下需要对 response.content进行解码，将其从 bytes 类型转为 str 类型
### 具体操作：
### bytes.decode(response.content) 或者 response.content.decode()
