无法使用python请求发布文件+数据 [英] unable to post file+data using python-requests

问题描述

我可以使用curl张贴文件

I'm able to post file using curl

curl -X POST -i -F name='barca' -F country='spain' -F 
file=@/home/messi/Desktop/barca.png 'http://localhost:8080/new_org/hel/concerts'

我可以得到（文件）为

 curl -X GET -H 'Accept: image/png' 'http://localhost:8080/new_org/hel/concerts/<id or name of entity>'

但是当我使用 requests.post 尝试相同的操作时，出现了错误。有谁知道为什么会这样。 （当文件指针不在最后，但是文件指针在最后时，遇到Post Post遇到错误200，但文件没有发布）

But when I tried same thing using requests.post, I got error. Does anybody know why this happen. (Post Error encounter when file pointer is not at last, but when file pointer is at last, I got response 200 but file is not posted)

import requests
url = 'http://localhost:8080/new_org/hel/concerts'
file = dict(file=open('/home/messi/Desktop/barca.png', 'rb'))
data = dict(name='barca', country='spain')
response = requests.post(url, files=file, data=data)

错误：（来自 usergrid ），其响应代码为：400

Error: (from usergrid) with response code: 400

{u'duration': 0,
 u'error': u'illegal_argument',
 u'error_description': u'value is null',
 u'exception': u'java.lang.IllegalArgumentException',
 u'timestamp': 1448330119021}

推荐答案

我相信问题是Python没有发送您要发送的图像的内容类型字段。我使用调试器跟踪了Usergrid代码，发现curl 是发送图像的内容类型，而Python不是。

I believe the problem is that Python is not sending a content-type field for the image that you are sending. I traced through the Usergrid code using a debugger and saw that curl is sending the the content-type for the image and Python is not.

我能够获得此确切的代码以在我的本地Usergrid上运行：

I was able to get this exact code to work on my local Usergrid:

import requests
url = 'http://10.1.1.161:8080/test-organization/test-app/photos/'
files = { 'file': ('13.jpg', open('/Users/dave/Downloads/13.jpg', 'rb'), 'image/jpeg')}
data = dict(name='barca', country='spain')
response = requests.post(url, files=files, data=data)

由于文件的语法，Waken Meng的答案可能无法正常工作变量，但我不是Python专家。

It is possible that Waken Meng's answer did not work because of the syntax of the files variable, but I'm no Python expert.
