Conversion of curl to python Requests
提问by zalc
I'm trying to convert the following working request in curl to a python request (using the Requests http://docs.python-requests.org/en/v0.10.7/).
我正在尝试将 curl 中的以下工作请求转换为 python 请求（使用请求http://docs.python-requests.org/en/v0.10.7/）。
curl --data 'query={"tags":["test1","test2"]}' http://www.test.com/match
(please note, I've used a fake url but the command does work with the real url)
（请注意，我使用了假网址，但该命令确实适用于真实网址）
The receiving end (ran in Flask) does this:
接收端（在 Flask 中运行）执行以下操作：
@app.route("/match", methods=['POST'])
def tagmatch():
query = json.loads(request.form['query'])
tags = query.get('tags')
... does stuff ...
return json.dump(stuff)
In curl (7.30), ran on Mac OS X (10.9) the command above properly returns a json list that filtered using the tag query.
在 curl (7.30) 中，在 Mac OS X (10.9) 上运行，上面的命令正确返回使用标签查询过滤的 json 列表。
My python script is as follows, it returns a 400 bad request.
我的python脚本如下，它返回一个400错误的请求。
import requests
payload = {"tags":["test1", "test2"]}
# also tried payload = 'query={"tags":["test1","test2"]}'
url = 'http://www.test.com/match'
r = requests.post(url, data=payload)
if __name__=='__main__':
print r.text
I feel I'm missing something small and any help would be appreciated.
我觉得我错过了一些小东西，任何帮助将不胜感激。
Thank you
谢谢

Your server is expecting JSON, but you aren't sending it. Try this:
您的服务器需要 JSON，但您没有发送它。尝试这个：
import requests
import json
payload = {'query': json.dumps({"tags":["test1", "test2"]})}
url = 'http://www.test.com/match'
r = requests.post(url, data=payload)
if __name__=='__main__':
print r.text

From your code using requestsand in Flask, it seems like you don't post the right data format. The payloadshould be like this:
从您requests在 Flask 中使用和的代码来看，您似乎没有发布正确的数据格式。该有效载荷应该是这样的：
payload = {'query': {'tags': ['test1', 'test2']},}
This seems not normal as post data when using requests.post(). So if you have posted the html form here, it may have been more clear to solve the problem.
Here is another similar question: Using Python Requests to pass through a login/password
使用requests.post(). 所以如果你把html表单贴在这里，解决问题可能就更清楚了。

There is a wonderful open source cURL to Python Requests conversion helper at http://curl.trillworks.com. It isn't perfect, but helps out a lot of the time. Especially for converting Chrome "Copy as cURL" commands. There is also a node libraryif you need to do the conversions programmatically
http://curl.trillworks.com 上有一个很棒的开源 cURL 到 Python 请求转换助手。它并不完美，但在很多时候会有所帮助。特别是用于转换 Chrome 的“Copy as cURL”命令。如果您需要以编程方式进行转换，还有一个节点库

I wrote an HTTP client plugin for Sublime Text called Requester, and one of its features is to convert calls to cURL to Requests, and vice versa.
我为 Sublime Text 编写了一个 HTTP 客户端插件，名为Requester，它的功能之一是将调用 cURL转换为 Requests，反之亦然。
If you're using Sublime Text this is probably your fastest, easiest option. If not, here's the code that actually handles the conversion from cURL to Requests. It's based uncurl, but with various improvements and bug fixes.
如果您使用 Sublime Text，这可能是您最快、最简单的选择。如果没有，这里是实际处理从 cURL 到请求的转换的代码。它基于uncurl，但有各种改进和错误修复。

You could make a script with this code, e.g. curl_to_request.py, and call this script from the command line like so. It will work for both Python 2 and Python 3.
您可以使用此代码创建一个脚本，例如curl_to_request.py，并像这样从命令行调用此脚本。它适用于 Python 2 和 Python 3。
python curl_to_request.py curl -X POST -d 'key2=value2&key1=value1' 'http://httpbin.org/post'
python curl_to_request.py curl -X POST -H 'Content-Type: application/json' -d '{"key2": "value2", "key1": "value1"}' 'http://httpbin.org/post'
python curl_to_request.py curl -X POST -H 'Content-Type: application/json' -d '[1, 2, 3]' 'http://httpbin.org/post'
python curl_to_request.py curl -X POST -H 'Content-Type: application/json' -d '{"name": "Jimbo", "age": 35, "married": false, "hobbies": ["wiki", "pedia"]}' 'http://httpbin.org/post'
python curl_to_request.py curl -X GET 'http://httpbin.org/get?key2=value2&key1=value1'
python curl_to_request.py curl -X GET -H 'key1: value1' -H 'key2: value2' 'http://httpbin.org/headers'
python curl_to_request.py curl -X GET -b 'key1=value1;key2=value2' 'http://httpbin.org/cookies'

A simpler approach would be:
一个更简单的方法是：
- Open POSTMAN
- Click on the "import" tab on the upper left side.
- Select the Raw Text option and paste your cURL command.
- Hit import and you will have the command in your Postman builder!
- 打开邮递员
- 单击左上角的“导入”选项卡。
- 选择原始文本选项并粘贴您的 cURL 命令。
- 点击导入，您将在 Postman 构建器中拥有该命令！
Hope this helps!
希望这可以帮助！

Try to use uncurllibrary. It is pretty nice to do its job. I've tried it.
尝试使用uncurl库。做它的工作非常好。我试过了。
u = uncurl.parse(
"curl -X GET 'https://mytesturl.com/' -H 'accept: application/json' -H 'Authorization: 1234567890'")
print(u)
It prints,
它打印，
requests.get("https://mytesturl.com/",
headers={
"Authorization": "1234567890",
"accept": "application/json"
},
cookies={},
)
