问题
I have eclispe maven project based on Azure services. I want to run it on client's machine who is from another country, so have different time zone.
When I install eclipse on their machine and run all the services, those works fine. But when I added war to apache folder , after running it, it's giving error like :
Make sure the value of Authorization header is formed correctly including the signature.
at com.microsoft.azure.storage.StorageException.translateException(StorageException.java:)
I came to this link and I think I am having almost same type of error :
StorageException for azure blob with java
Please tell me how to solve this and how to make clock 'slow' as mentioned in the answer of provided link.
Here is the code : (See the code in else loop from first method. It's blob related code.)

Method to create shared access blob policy :
private final static SharedAccessBlobPolicy createSharedAccessBlobPolicy(EnumSet<SharedAccessBlobPermissions> sap,
int expireTimeInSeconds) {
Calendar cal = new GregorianCalendar(TimeZone.getTimeZone("UTC"));
cal.setTime(new Date());
cal.add(Calendar.YEAR, expireTimeInSeconds);
SharedAccessBlobPolicy policy = new SharedAccessBlobPolicy();
policy.setPermissions(sap);
policy.setSharedAccessExpiryTime(cal.getTime());
return policy;
}
What changes I should make here?
回答1:
I have faced similar problem before. What you need to do is , make your code comfortable for all the time zones like GMT,IST,EST etc. Because when you upload war in server of another country, your code must be 'clever' enough to understand time zone of that country !
So here is what you can do :
Step 1:
In third part of your code , try replaceing "UTC" by your client machine's timezone like GMT,EST etc.
If that works (and I am pretty much sure that it will work fine) , go for
Step 2:
First of all we will code something that gives you current time zone in String like "Indian Standard Time" or "European Standard Time" etc.
Then, we will pick only first letters from all words and make a String like "IST" or "EST".
At last, we will pass this String at place where you wrote "UTC" in third part of your code.
So, here is the code :
private final static SharedAccessBlobPolicy createSharedAccessBlobPolicy(EnumSet<SharedAccessBlobPermissions> sap,
int expireTimeInSeconds) {
Calendar now = Calendar.getInstance();
TimeZone timeZone = now.getTimeZone();
System.out.println("Current TimeZone is : " + timeZone.getDisplayName());
String x = timeZone.getDisplayName();
String[] myName = x.split(" ");
String s = "";
ArrayList zoneArray = new ArrayList<>();
char zone = 0;
for (int i = 0; i < myName.length; i++) {
s = myName[i];
System.out.print(s.charAt(0));
zone = s.charAt(0);
zoneArray.add(zone);
}
String timeZoneCurrent = s;
String timeZoneDynamic = zoneArray.toString().replace(",", "").replace(" ", "").replace("[", "").replace("]",
"");
System.out.println("Value of S==========" + timeZoneDynamic);
Calendar cal = new GregorianCalendar(TimeZone.getTimeZone(timeZoneDynamic));
cal.setTime(new Date());
cal.add(Calendar.YEAR, expireTimeInSeconds);
SharedAccessBlobPolicy policy = new SharedAccessBlobPolicy();
policy.setPermissions(sap);
policy.setSharedAccessExpiryTime(cal.getTime());
return policy;
}
In this, timeZoneDynamic has values like "IST" , "GMT" etc. This logic must work. If have any error, post it in edit. Hope that will work.
回答2:
Without the code it is hard to tell, however there is a chance that the times on the client or at the server are not in utc or wrongly converted.
Check the time and timezones of the machine. If they match, check your code if the utc time or local time is used.
回答3:
Per my experience, the issue was caused by the incorrect code in the method private final static SharedAccessBlobPolicy createSharedAccessBlobPolicy to get the UTC time via Calendar .
As reference, Here is my sample code to get UTC time using Calendar.
Calendar cal = Calendar.getInstance() ;
// Get the time zone offset
int zoneOffset = cal.get(Calendar.ZONE_OFFSET);
// Get the daylight-saving time offset
int dstOffset = cal.get(Calendar.DST_OFFSET);
// Reduce these offsets above from local time to get UTC time
cal.add(Calendar.MILLISECOND, -(zoneOffset + dstOffset));
System.out.println(cal.getTime());
Then, to add the expire time seconds to get the final date time.
