Basic usage
Sentry Of SDK Hook into your runtime environment , And automatically report errors (errors)、 abnormal (exceptions) And refuse to (rejections).
Key terms ：
- event Is to Sentry An example of sending data . Usually , The data is an error (
error) Or abnormal (exception). - issue It's a set of similar events .
- The report of the incident is called capturing. After capturing the event , It will be sent to Sentry.
The most common form of capture is capture errors (capture errors). The errors that can be caught vary from platform to platform . Usually , If you have something that looks like an exception (exception) Things that are , It can be captured . For certain SDK, You can also omit capture_exception Parameters of ,Sentry Will attempt to catch the current exception . To Sentry It's also useful to report errors or messages manually .
When capturing Events , You can also record the crumbs that caused the event （breadcrumbs）. Breadcrumbs are different from events ： They won't be Sentry Create events in , But it will be buffered before sending the next event . In our Breadcrumbs documentation Learn more about crumbs in .
Capture the error
stay JavaScript in , You can pass the error object to captureException(), To capture it as an event . You can throw a string as an error , In this case, backtracking cannot be recorded .
try {
aFunctionThatMightFail();
} catch (err) {
Sentry.captureException(err);
}
Capture naked messages
Another common operation is to capture naked messages （bare message）. The message should be sent to Sentry The text message of . Usually , The message won't go out , But they can be useful for some teams .
Sentry.captureMessage("Something went wrong");
Set the event level
level — Similar to log level — It's usually based on Integration （integration） Default added . You can also override it in an event .
To be in scope External settings level, You can call captureMessage() Every event ：
Sentry.captureMessage("this is a debug message", "debug");
To be in scope （scope） Set levels in , You can call setLevel()：
Sentry.configureScope(function(scope) {
scope.setLevel(Sentry.Severity.Warning);
});
Or every event ：
Sentry.withScope(function(scope) {
scope.setLevel("info");
Sentry.captureException("info");
});
