我想在python中执行curl命令.
通常,我只需要在终端输入命令并按回车键.但是,我不知道它在python中是如何工作的.
该命令如下所示:
curl -d @request.json --header "Content-Type: application/json" https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere

有一个request.json文件要发送以获得响应.
我经常搜索并感到困惑.我试着写一段代码,虽然我无法完全理解.它没用.
import pycurl
import StringIO
response = StringIO.StringIO()
c = pycurl.Curl()
c.setopt(c.URL, 'https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere')
c.setopt(c.WRITEFUNCTION, response.write)
c.setopt(c.HTTPHEADER, ['Content-Type: application/json','Accept-Charset: UTF-8'])
c.setopt(c.POSTFIELDS, '@request.json')
c.perform()
c.close()
print response.getvalue()
response.close()

错误信息是'Parse Error'.任何人都可以告诉我如何修复它?或者如何正确地从服务器获得响应?

为简单起见,您可以考虑使用标准库 请求.
json响应内容的示例如下:
import requests
r = requests.get('https://github.com/timeline.json')
r.json()

对于您的特定卷曲翻译:
import requests
url = 'https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere'
payload = open("request.json")
headers = {'content-type': 'application/json', 'Accept-Charset': 'UTF-8'}
r = requests.post(url, data=payload, headers=headers)

只需使用这个网站.它会将任何curl命令转换为Python,Node.js,PHP,R或Go.
例:
curl -X POST -H 'Content-type: application/json' --data '{"text":"Hello, World!"}' https://hooks.slack.com/services/asdfasdfasdf

在Python中成为现实,
import requests
headers = {
'Content-type': 'application/json',
}
data = '{"text":"Hello, World!"}'
response = requests.post('https://hooks.slack.com/services/asdfasdfasdf', headers=headers, data=data)

也许?
如果您要发送文件
files = {'request_file': open('request.json', 'rb')}
r = requests.post(url, files=files)
print r.text, print r.json

啊,谢谢@LukasGraf现在我更好地理解他原来的代码在做什么
import requests,json
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere"
my_json_data = json.load(open("request.json"))
req = requests.post(url,data=my_json_data)
print req.text
print
print req.json # maybe?

curl -d @request.json --header "Content-Type: application/json" https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere

它的python实现就像
import requests
headers = {
'Content-Type': 'application/json',
}
params = (
('key', 'mykeyhere'),
)
data = open('request.json')
response = requests.post('https://www.googleapis.com/qpxExpress/v1/trips/search', headers=headers, params=params, data=data)
#NB. Original query string below. It seems impossible to parse and
#reproduce query strings 100% accurately so the one below is given
#in case the reproduced version is not "correct".
# response = requests.post('https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere', headers=headers, data=data)

我的答案是 WRT python 2.6.2。
import commands
status, output = commands.getstatusoutput("curl -H \"Content-Type:application/json\" -k -u (few other parameters required) -X GET https://example.org -s")

我很抱歉没有提供所需的参数,因为它是机密的。

一些背景:我一直在寻找这个问题,因为我必须做一些事情来检索内容,但我所拥有的只是一个旧版本的 python,SSL 支持不足。如果您使用的是较旧的 MacBook,就会知道我在说什么。在任何情况下,curl从 shell 运行良好(我怀疑它链接了现代 SSL 支持)所以有时你想不使用requests或urllib2.
您可以使用该subprocess模块执行curl并获取检索到的内容:
import subprocess
// 'response' contains a []byte with the retrieved content.
// use '-s' to keep curl quiet while it does its job, but
// it's useful to omit that while you're still writing code
// so you know if curl is working
response = subprocess.check_output(['curl', '-s', baseURL % page_num])

Python 3 的subprocess模块还包含.run()许多有用的选项。我会把它留给实际运行 python 3 的人来提供答案。
我使用os图书馆。
import os
os.system("sh script.sh")

script.sh实际上只包含卷曲。
