详解python上传文件和字符到PHP服务器

def send_str_server(self):
payload = {'key1': 'value1', 'key2': 'value2'}
r = requests.post("http://httpbin.org/post", 
data=payload)

def send_image_server(self):
data = {"k1" : "v1"} 
files = {"img" : open("test.png", "rb")} 
r = requests.post("http://httpbin.org/post", data,
files=files)

#!usr/bin/python
# image.py
# -*- coding=utf-8 -*-

from poster.encode import multipart_encode
from poster.streaminghttp import register_openers

register_openers()
f=open(“C:/Users/User/Pictures/Saved Pictures/test1.jpg”, "rb")
#f=open(sys.argv[1], "rb") 使用sys.argv[1]可调用参数 例如 运行 python image.py C:/Users/User/Pictures/Saved Pictures/test1.jpg 
#可将test1.jpg作为参数传入image.py
#"C:/Users/User/Pictures/Saved Pictures/vedio5.jpg"
# headers 包含必须的 Content-Type 和 Content-Length
# datagen 是一个生成器对象，返回编码过后的参数
datagen, headers = multipart_encode({"myFile": f})
# 创建请求对象
request = urllib2.Request("http://localhost/upload_image/upload_image.php", datagen, headers)
try:
response = urllib2.urlopen(request)
print response.read()
