The signed key(sw) is https://api.dropbox.com/1/shares/dropbox/a.jpg?oauth_consumer_key=2f2y1dyuqhp58ek&oauth_token=wz27t6thob0fbxl&oauth_nonce=1340648163&oauth_timestamp=1340648163&oauth_signature_method=HMAC-SHA1&oauth_version=1.0&oauth_signature=bo%2F5zuowvX%2Fcjy5uPP5ZPjUiP64% 3D%0A

我对http没有太多经验..

因为 httpPost = new HttpPost(sw); 工作正常，这是否意味着基本字符串签名是正确的？

还是我错过了什么？

这似乎与 OAuth 错误无关。根据以下日志声明，您似乎没有在 http post url 中设置主机。

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