微信公众号素材管理

一,上传永久图片素材,可以用以下2种方式:

1.公众号素材管理中直接上传

2.发送POST请求

使用curl命令上传示例:

curl -F media=@pro_nlp.jpg "http://file.api.weixin.qq.com/cgi-bin/material/add_material?access_token=14_3-OW6zGI-yD1LzYlhovytEU81rqH6gDIrYimb4xb_Jriwizb_5XPiaqP7PwCPrMICJ6COq0LS5Rrjxbm0NXpd_C3vhQWrbVMT_iniCvmMwPDfdO1Ekc0pFdlf78PHTgAEAEWI"

使用Python脚步上传示例:

# -*- coding: utf-8 -*-
# filename: media.py
#from basic import Basic
import urllib2
import poster.encode
from poster.streaminghttp import register_openers

class Media(object):
    def __init__(self):
        register_openers()
    #上传图片
    def uplaod(self, accessToken, filePath, mediaType):
        openFile = open(filePath, "rb")
        param = {'media': openFile}
        postData, postHeaders = poster.encode.multipart_encode(param)

        #postUrl = "https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=" + accessToken + "&type=" + mediaType
        postUrl = "http://file.api.weixin.qq.com/cgi-bin/material/add_material?access_token=" + accessToken + "&type=" + mediaType
        request = urllib2.Request(postUrl, postData, postHeaders)
        urlResp = urllib2.urlopen(request)
        print(urlResp.read())

if __name__ == '__main__':
    myMedia = Media()
    accessToken = "14_s9rzbBYHo-eI-hM10l4PuoPp2KSW7obCG3yhFpUn6jhxJlo_d-HC37c8NqUD8Ydfy1mnhD0nNCOgMPLwMb5sIsk6PlhAGatPO6pPhr3mvfOwHH8RgFJ7zCq_iZHb-Kubt8xWqzwn2hK4rQ5pBVPiAAAHBV"
    filePath = "/home/ytkj/temp/pro_nlp.jpg"   #请安实际填写
    mediaType = "image"
    myMedia.uplaod(accessToken, filePath, mediaType)

 

二,获取素材的MediaID

1.上传时可以直接得到素材的mediaid

2.使用接口获取素材列表

# -*- coding: utf-8 -*-
# filename: material.py
import urllib2
import json
import poster.encode
from poster.streaminghttp import register_openers

class Material(object):
    def __init__(self):
        register_openers()
    #上传
    def uplaod(self, accessToken, filePath, mediaType):
        openFile = open(filePath, "rb")
        fileName = "hello"
        param = {'media': openFile, 'filename': fileName}
        #param = {'media': openFile}
        postData, postHeaders = poster.encode.multipart_encode(param)

        postUrl = "https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=%s&type=%s" % (accessToken, mediaType)
        request = urllib2.Request(postUrl, postData, postHeaders)
        urlResp = urllib2.urlopen(request)
        print urlResp.read()
    #下载
    def get(self, accessToken, mediaId):
        postUrl = "https://api.weixin.qq.com/cgi-bin/material/get_material?access_token=%s" % accessToken
        postData = "{ \"media_id\": \"%s\" }" % mediaId
        urlResp = urllib2.urlopen(postUrl, postData)
        headers = urlResp.info().__dict__['headers']
        if ('Content-Type: application/json\r\n' in headers) or ('Content-Type: text/plain\r\n' in headers):
            jsonDict = json.loads(urlResp.read())
            print jsonDict
        else:
            buffer = urlResp.read()  # 素材的二进制
            mediaFile = file("test_media.jpg", "wb")
            mediaFile.write(buffer)
            print "get successful"
    #删除
    def delete(self, accessToken, mediaId):
        postUrl = "https://api.weixin.qq.com/cgi-bin/material/del_material?access_token=%s" % accessToken
        postData = "{ \"media_id\": \"%s\" }" % mediaId
        urlResp = urllib2.urlopen(postUrl, postData)
        print urlResp.read()

    #获取素材列表
    def batch_get(self, accessToken, mediaType, offset=0, count=20):
        postUrl = ("https://api.weixin.qq.com/cgi-bin/material"
               "/batchget_material?access_token=%s" % accessToken)
        postData = ("{ \"type\": \"%s\", \"offset\": %d, \"count\": %d }"
                    % (mediaType, offset, count))
        urlResp = urllib2.urlopen(postUrl, postData)
        print urlResp.read()

if __name__ == '__main__':
    myMaterial = Material()
    accessToken = "14_-GQ-SnXSuyd-LZ0Q-iy0y4-Xlm0rGtwaRjf5C6UIjMGWqeQD1gM9lC8OL1ArLoT9fr59-ff1pZcj_5E9uUXbFY77cGiVvPYq6RoZMWeZpjEPqIW5cwaT5YVgkscaV9lTYpIcd8Ocla2MJiBfPOUaAEABAG"
    mediaType = "image"
    myMaterial.batch_get(accessToken, mediaType)

 

三,公众号回复消息格式

3.其他参考,注意微信开发者文档中有错误,回复消息格式中多了空格
