我在Scala上尝试了mklink .htaccess C:\path\outside\.htaccess
mklink /D .upload C:\path\outside\upload
，但收到了错误GET https://api.twitter.com/1.1/statuses/user_timeline.json?count=1&user_id=XXX。
这是我的规格：
401 Authorization required：
build.sbt name := "hoge"
version := "1.0"
libraryDependencies ++= Seq(
"com.typesafe.play" %% "play-ws" % "2.4.0-M2",
"commons-codec" % "commons-codec" % "1.3.0"
)

}
，timestamp，nonce和sign
oauthHeader我做了timestamp = 1482542041
nonce = 214129951907166
sign = YWQ2Y2VjNzJkOTQwY2JhYjEzYzgxZDM2YTg3ZGNlNjQ3ZjIzMDQ4Yw==
oauthHeader = OAuth oauth_consumer_key="AAA", oauth_nonce="214129951907166", oauth_signature="YWQ2Y2VjNzJkOTQwY2JhYjEzYzgxZDM2YTg3ZGNlNjQ3ZjIzMDQ4Yw%3D%3D", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1482542041", oauth_token="CCC", oauth_version="1.0"
然后sbt compile，得到了回复sbt run。
我认为401 Authorization required和val ws = NingWSClient()之间没有问题：当我发送不需要OAuth 1.0的GET / POST请求（例如Google API）时，我成功了。
我还认为消费者密钥，消费者秘密，令牌，令牌秘密是正确的：当我在Ruby上运行类似的过程时，一切都很好。
我认为签名的过程是正确的，因为我一遍又一遍地在文档中检查过它。
所以，我认为编码或加密它们是错误的。 我不想使用Twitter4J库，因为我只是在研究Scala。
请告诉我这是什么问题。
答案 0 :(得分：0)
URLEncoder.encode为＆＃39; +＆＃39;不是＆＃39;％20＆＃39;，所以放replace("+", "%20")。
加密变为：
val hmacShai = "HmacSHA1"
val keyStr = new SecretKeySpec(bytes(key), hmacShai)
val sig = {
val mac = Mac.getInstance(hmacShai)
mac.init(keyStr)
new String(base64encode(mac.doFinal(bytes(data))))
}
