OAuthGetRequestToken：signature_invalid错误
|
我尝试使用Google数据API，并在OAuthGetRequestToken遇到困难。
我遵循指令：requestToken
我使用GET并在URL后添加查询参数。
我以这种方式创建用于签名的基本字符串：
GET＆request url＆query参数（不带oauth_signature）按字母顺序排序
当我使用HMAC-SHA1时，我使用“消费者秘密”值来创建签名。
最后，我使用url + query参数，浏览器始终返回：
signature_invalid
base_string：GET＆https％3A％2 ＊＊＊＊＊＊
我发现base_string与我的代码中的相同。
我不知道问题出在哪里并寻求帮助。
下面是我的代码：
（hmac_sha1是正确的，因为我使用来自Oauth的示例数据进行测试）
