Question

我已经获得了以下curl命令作为API文档的一部分，我正在尝试使用请求库来实现它。

curl -v --cookie cookie.txt -X POST -H 'Accept: application/json' -F 'spot[photo]'=@rails.png -F 'spot[description]'=spot_description -F 'spot[location_id]'=9  -F 'spot[categories][]'='See the Sights' -F 'spot[categories][]'='Learn Something' http://some.server.com/api/v1/spots

我的python代码看起来像这样：

import requests
import json

_user = 'redacted'
_password = 'redacted'
_session = requests.session()
_server = 'http://some.server.com'

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

_login_payload = {
    'user': {
        'email': _user,
        'password': _password
    }
}
r = _session.post(_server + "/users/sign_in", data=json.dumps(_login_payload), headers=_hdr)
print json.loads(r.content)

_spot_payload = {
    'spot': {
        'photo': '@rails.gif',
        'description': 'asdfghjkl',
        'location_id': 9,
        'categories': ['See the Sights',]
    }
}
r = _session.post(_server + '/api/v1/spots', data=json.dumps(_spot_payload), headers=_hdr)
print json.loads(r.content)

我听说你可以使用open（'file'）。read（）来发布文件，但json编码器不太喜欢这个，我不确定是否可以解决这个问题。< / p>

C:\>cat file.txt
Some text.

发出此命令时：

C:\>curl -X POST -H "Accept:application/json" -F "spot[photo]=@file.txt"
-F "spot[description]=spot_description" http://localhost:8888

发送的内容如下：

POST / HTTP / 1.1 User-Agent：curl / 7.25.0（i386-pc-win32）libcurl / 7.25.0   OpenSSL / 0.9.8u zlib / 1.2.6 libssh2 / 1.4.0主机：localhost：8888接受：   application / json内容长度：325期望：100-continue   内容类型：multipart / form-data;   边界= ---------------------------- e71aebf115cd

------------------------------ e71aebf115cd Content-Disposition：form-data; NAME = “斑〔照片]”; filename =“file.txt”内容类型：   文本/纯

一些文字。   ------------------------------ e71aebf115cd Content-Disposition：form-data; NAME = “斑点[描述]”

spot_description   ------------------------------ e71aebf115cd -

正如您所见，curl发送请求Content-Type设置为multipart/form-data;请求support使用相同的Content-Type发送文件。你应该使用files参数。

(2.7) C:\>python

>>> requests.__version__
'0.11.1'
>>> requests.post('http://localhost:8888', files={'spot[photo]': open('file.txt', 'rb')}, data={'spot[description]': 'spot_description'})
<Response [200]>

发送的内容如下：

POST http://localhost:8888/ HTTP/1.1
Host: localhost:8888

Content-Type: multipart/form-data; boundary=192.168.1.101.1.8000.1334865122.004.1

spot_description

Some text.

使用python请求和json发布文件
