我正在尝试使用 update_with_media.json 将图像发布到 Twitter。
以下是使用 statuses/update.json 更新推文的工作代码
local url = "http://api.twitter.com/1/statuses/update.json"
local consumer_key = ""
local consumer_secret = ""
local token = ""
local token_secret = ""
local post_data =
{
oauth_consumer_key = consumer_key,
oauth_nonce = get_nonce(),
oauth_signature_method = "HMAC-SHA1",
oauth_token = token,
oauth_timestamp = get_timestamp(),
oauth_version = '1.0',
oauth_token_secret = token_secret
}
post_data["status"] = "Hello Twitter!"
post_data = oAuthSign(url, "POST", post_data, consumer_secret)
r,c,h = http.request
{
url = url,
method = "POST",
headers =
{
["Content-Type"] = "application/x-www-form-urlencoded",
["Content-Length"] = string.len(rawdata)
},
source = ltn12.source.string(post_data),
sink = ltn12.sink.table(response)
}
现在如何修改上面的代码来上传图片?url 为“http://api.twitter.com/1/statuses/update_with_media.json”,headers[“Content-Type”] 为“multipart/form-data”
但是我在哪里以及如何指定要上传的图像?
