折腾:

[已解决]微信后台服务器如何发送图片给微信公众号的关注者用户

期间,Flask中,用代码:

respTicket = respQrcodeJson[‘ticket’]
app.logger.debug(‘respTicket=%s’, respTicket)
respQrcode = wechat.show_qrcode(respTicket)
app.logger.debug(‘type(respQrcode)=%s, respQrcode=%s’, type(respQrcode), respQrcode)
respQrcodeContent = respQrcode.content
#app.logger.debug(‘type(respQrcodeContent)=%s, respQrcodeContent=%s’, type(respQrcodeContent), respQrcodeContent)
app.logger.debug(‘type(respQrcodeContent)=%s’, type(respQrcodeContent))
# save qrcode data to tmp file
curTimestamp = time.time()
app.logger.debug(“type(curTimestamp)=%s, curTimestamp=%s”, type(curTimestamp), curTimestamp)
qrcodeFullPath = “/tmp/%.3f.jpg” % (curTimestamp)
app.logger.debug(“qrcodeFullPath=%s”, qrcodeFullPath)
with open(qrcodeFullPath, ‘wb’) as f:
    f.write(respQrcodeContent)
    f.close()
    app.logger.debug(“saved qrcode image to %s ok”, qrcodeFullPath)
with open(qrcodeFullPath, ‘rb’) as qrcodeFile:
    app.logger.debug(“type(qrcodeFile)=%s, qrcodeFile=%s”, type(qrcodeFile), qrcodeFile)
    uploadMediaResp = wechat.upload_media(media_type=”image”, media_file=qrcodeFile)
    app.logger.debug(“uploadMediaResp=%s”, uploadMediaResp)
    qrcodeFile.close()

结果出错:

去看了看代码:

可能是我自己的问题,

至少是:

我对于:

/root/Envs/SIPEvents/lib/python2.7/site-packages/wechat_sdk-0.6.4-py2.7.egg/wechat_sdk/lib/request.py

把之前的:

def request(self, method, url, access_token=None, **kwargs):

的:

        r = requests.request(
            method=method,
            url=url,
            **kwargs
        )

加了headers,变成了:

        r = requests.request(
            method=method,
            headers = {
                ‘Content-Type’ : ‘application/json; charset=UTF-8’,
                ‘Accept-Type’ : ‘application/json; charset=UTF-8’
            },
            url=url,
            **kwargs
        )

所以,先去掉之前加上的这个headers再说。

然后就可以了。。。

[总结]

此处之所以用python的微信的SDK wechat-python-sdk的调用:

wechat.upload_media

去上传文件,之所以出错:

OfficialAPIError: 41005: media data missing hint: [ScXL0536e292]

是因为之前对于:

wechat_sdk-0.6.4-py2.7.egg/wechat_sdk/lib/request.py

调试期间,把:

        r = requests.request(
            method=method,
            url=url,
            **kwargs
        )

改为了:

        r = requests.request(
            method=method,
            headers = {
                ‘Content-Type’ : ‘application/json; charset=UTF-8’,
                ‘Accept-Type’ : ‘application/json; charset=UTF-8’
            },
            url=url,
            **kwargs
        )

导致此处post上传文件时,内部数据处理异常,估计是导致找不到media项了,

所以才报此错误。

解决办法是:

去掉即可,变为原先的:

        r = requests.request(
            method=method,
            url=url,
            **kwargs
        )

即可正常上传资源文件。

另外,根据官网:

新增临时素材 – 微信公众平台开发者文档

的解释,请注意:

上传资源文件时,注意不要超过大小限制:

“注意事项

上传的临时多媒体文件有格式和大小限制,如下:

  • 图片(image): 1M,支持JPG格式
  • 语音(voice):2M,播放长度不超过60s,支持AMR\MP3格式
  • 视频(video):10MB,支持MP4格式
  • 缩略图(thumb):64KB,支持JPG格式

媒体文件在后台保存时间为3天,即3天后media_id失效。”
