签名密钥（sw）为https://api.dropbox.com/1/shares/dropbox/a.jpg?oauth_consumer_key=2f2y1dyuqhp58ek

我对http没有太多经验。。

因为httpPost=新的httpPost（sw）；工作正常，这是否意味着基本字符串签名正确？

还是我错过了什么？

这似乎与OAuth错误无关。根据以下日志语句，您似乎没有在超文本传输协议post url中设置主机。

Caused by: java.lang.IllegalStateException: Target host must not be null, or set in parameters.
