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 'localhost:8080/new_org/hel/concerts'我可以得到(文件)为
curl -X GET -H 'Accept: image/png' '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 = '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}github/apache/usergrid
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 = '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.
