REST API (XML)：执行复制时400错误请求(缺少复制源)

Question

我正在尝试使用XML API和x-goog- headers复制Google Cloud Storage上的一个对象。即使存在x-goog- copy -source标头，也会收到400错误请求，并显示“缺少复制源”。

Answer 1

x-goog-copy-source中的值格式不正确。

我建议您尝试运行如下命令，以查看gsutil生成的HTTP请求：

gsutil -o GSUtil:prefer_api=xml -d cp gs://your-source-bucket/your-source-object gs://your-dest-bucket/your-dest-object

然后，您可以将它生成的标题与您使用的标题进行比较。
