python实现requests发送/上传多个文件的示例

url = "http://httpbin.org/post" 
data = None 
files = { ... } 
r = requests.post(url, data, files=files) 

{ 
 "field1" : ("filename1", open("filePath1", "rb")), 
 "field2" : ("filename2", open("filePath2", "rb"), "image/jpeg"), 
 "field3" : ("filename3", open("filePath3", "rb"), "image/jpeg", {"refer" : "localhost"}) 
} 

("filename", "fileobject", "content-type", "headers") 

{ 
 "field1" : open("filePath1", "rb")), 
 "field2" : open("filePath2", "rb")), 
 "field3" : open("filePath3", "rb")) 
} 

{ 
 "field1" : ("filename1", open("filePath1", "rb")), 
 "field2" : ("filename2", open("filePath2", "rb")), 
 "field3" : ("filename3", open("filePath3", "rb")) 
} 

{ 
 "field1" : open("filePath1", "rb").read()) 
} 

[ 
 ("field1" : ("filename1", open("filePath1", "rb"))), 
 ["field2" : ("filename2", open("filePath2", "rb"), "image/jpeg")], 
 ("field3" : ("filename3", open("filePath3", "rb"), "image/jpeg", {"refer" : "localhost"})) 
] 

[ 
 ("field1" : open("filePath1", "rb"))), ##filename 使用的是filepath的文件名 
 ("field2" : open("filePath2", "rb").read())) ##filename 使用的是键值，即 field2 
] 

{ 
 "field1" : [ 
   ("filename1", open("filePath1", "rb")), 
   ("filename2", open("filePath2", "rb"), "image/png"), 
   open("filePath3", "rb"), 
   open("filePath4", "rb").read() 
  ] 
} 

[ 
 ("field1" , ("filename1", open("filePath1", "rb"))), 
 ("field1" , ("filename2", open("filePath2", "rb"), "image/png")), 
 ("field1" , open("filePath3", "rb")), 
 ("field1" , open("filePath4", "rb").read()) 
] 

data = {"k1" : "v1"} 
files = { 
 "field1" : open("1.png", "rb") 
} 
r = requests.post("http://httpbin.org/post", data, files=files)
