requests 发送文件

使用 requests 库发送文件

files = {'upload_file': open('file.txt','rb')}

r = requests.post(url, files=files)

requests will send a multi-part form POST body with the upload_file field set to the contents of the file.txt file. The filename will be included in the mime header for the specific field

• mime header 中的文件名自动设置为 file.txt 也可以自己设置文件名，例如 filex：files = {'upload_file': ('filex', open('file.txt','rb'))}

还可以设置文件内容

files = {'upload_file': ('foobar.txt', open('file.txt','rb'), 'text/x-spam')}

发送文件的时候发送其它参数

files = {'upload_file': open('file.txt','rb')}
values = {'DB': 'photcat', 'OUT': 'csv', 'SHORT': 'short'}

r = requests.post(url, files=files, data=values)
