python requests 编码问题

url = host + path
headers = {...}
data = {...}
files = {...}

files两种类型: 字典和 元组

{
  "field1" : ("filename1", open("filePath1", "rb")),
  "field2" : ("filename2", open("filePath2", "rb"), "image/jpeg"),
  "field3" : ("filename3", open("filePath3", "rb"), "image/jpeg", {"refer" : "localhost"})
}
字段对应:{"字段名": ("filename","fileobject", "content-type", "headers")}

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

元组形式:

[
  ("field1" , ("filename1", open("filePath1", "rb"))),
  ("field2" , ("filename2", open("filePath2", "rb"), "image/jpeg")),
  ("field3" , ("filename3", open("filePath3", "rb"), "image/jpeg", {"refer" : "localhost"}))
]
字段对应:["字段名", ("filename","fileobject", "content-type", "headers")]

data = requests.post(url,files=files,data=data_dict,headers=headers)
print(data.content.decode("utf-8"))

注: 上述可能filename不支持中文名,可以 D:\Users\jiangbo.xu\AppData\Local\Programs\Python\Python35\Lib\site-packages\urllib3\fields.py 50行左右

    value = '%s*=%s' % (name, value) 改成 value = '%s=%s' % (name, value)
