无法使用http put将图像上传到Amazon s3

Question

我正在开发一个Android应用，用户可以在其中创建带有图像的帖子。 图像正在上传到Amazon S3。 因此，每个用户如何上传图像，我不使用Amazon AWS开发工具包，因为其方法需要密钥。 我尝试使用HTTP put请求上传图像。 我向后端发送了第一个请求，它向我发送了用于上传图像的签名和其他参数。 不幸的是，亚马逊的第二个回应包含错误。

这是第一个请求和响应：

所以我找到了解决方案。 是我的错，我发了

nameValuePairs.add(new BasicNameValuePair("file_type", "image/jpg"));

对于第一个请求，并且

Content-Type: image/jpeg

在第二个请求中。
