我正在使用下面提到的来自MS的快照休息api
https://myaccount.blob.core.windows.net/mycontainer/myblob?comp=snapshot
https://docs.microsoft.com/en-us/rest/api/storageservices/snapshot-blob
授权我生成的共享密钥适用于所有其他具有GET REST API调用的操作，例如GetBlob，ListContainer，ListBlob。
我认为对于POST调用我收到错误但是生成授权共享密钥的逻辑是相同的。

直接生成Authorization SharedKey的Java代码我们可以创建类并复制粘贴此代码：
public static void main（String ... arg）抛出URISyntaxException，Exception {
{{1}}
答案 0 :(得分：0)
通常，当您收到此类错误响应时，您应该检查服务器的字符串到符号（包含在错误响应中）并与您自己进行比较，并找出存在差异的原因。< / p>
在这种情况下，您可以看到＆＃34; comp＆＃34;查询参数有一个值＆＃34; snapshot？comp = snapshot /＆＃34;这是不正确的。请检查您的代码，以确保您没有附加＆＃34;？comp = snapshot＆＃34;两次到URL。 （实际发送给服务的那个，而不是用于计算签名的那个。）
答案 1 :(得分：0)
根据Azure存储的错误响应消息，我们需要为POST和Delete操作传递Content-length。
在上面的代码中，设置
之后requestHeaders.put（＆＃34; content-length＆＃34;，＆＃34; 0＆＃34;）;
它在工作。
