问题
I have a Apps Script where I Loop trough my Google Analytics Account till I get to
a certain Profile. if (profileItems[i].getName() == "Dev Test" )
Than in another function (see bellow) I make the call to the Google Analytics API and always get the Exception thrown: Exception: Quota Error: User Rate Limit Exceeded
function getReportDataForProfile(profileId) {
var tableId = 'ga:' + profileId;
var startDate = getLastNdays(14); // 2 weeks (a fortnight) ago.
var endDate = getLastNdays(0); // Today.
var optArgs = {
'dimensions': 'ga:keyword', // Comma separated list of dimensions.
'sort': '-ga:visits,ga:keyword', // Sort by visits descending, then keyword.
'segment': 'dynamic::ga:isMobile==Yes', // Process only mobile traffic.
'filters': 'ga:source==google', // Display only google traffic.
'start-index': '1',
'max-results': '250' // Display the first 250 results.
};
//
//Exponential Backoff
//
for (var n=0; n<6; n++) {
try {
var results = Analytics.Data.Ga.get(
tableId, // Table id (format ga:xxxxxx).
startDate, // Start-date (format yyyy-MM-dd).
endDate, // End-date (format yyyy-MM-dd).
'ga:visits,ga:pageviews', // Comma seperated list of metrics.
optArgs);
} catch(e) {
if (n == 5) {
//var results = e;
//throw new Error('Quota ERROR');
throw (e)
}
Utilities.sleep((Math.pow(2,n)*1000) + (Math.round(Math.random() * 1000)));
}
}
return results;
}
- I increased the number of the Per user Limit in the API Console to 10.0
- The used Porcentage is 6%
- And I applied the Exponential Backoff
- I also believe that by just asking for the Visits and PageViews I am not exagerating my number of calls.
The full code
Any ideias what is going on?

That's indeed because you are not allowed to query more than 10 requests per seconds. I'm posting a solution here (even if that's an old question) because it may help others:
/**
* CallLimiter
* @param {Number} numberOfCalls how many calls per duration are we allowed to do
* @param {Number} duration duration in ms
*/
function CallLimiter(numberOfCalls, duration){
var lastCall = 0;
var tokens = 0;
return function limiter(f){
var now = +new Date();
if (now - lastCall > duration) {
tokens = numberOfCalls;
}
if (tokens <= 0) {
tokens = numberOfCalls;
// wait for `duration` before calling limiter(f) again
return setTimeout(limiter.bind(this, f), duration);
}
tokens--;
lastCall = now;
f();
};
}
And here is how to use it:
// Stub...
var Analytics = {Data: {Ga:{get:function(cb){
cb();
}}}};
function app(){
// Wrap the api call inside a limiter
limiter(function(){
Analytics.Data.Ga.get(function(err, data){
// do something with the data...
// ... then, loop if necessary
app();
});
});
}
// Start
app();
And here is a blocking Scala version:
class CallLimiter(rate: Throttler.Rate) {
var lastCall = 0
var duration = rate.duration.toMillis
var current_tokens = 0
def apply[A](f: () => A): A = {
val d = new Date().getTime
if (d - lastCall > duration) {
current_tokens = rate.numberOfCalls
}
if (current_tokens <= 0) {
// wait for `duration` before calling f()
Thread.sleep(duration)
current_tokens = rate.numberOfCalls
}
current_tokens = current_tokens - 1
lastCall = d
f()
}
}
Usage:
import akka.contrib.throttle.Throttler
val limiter = new CallLimiter(new Rate(10, Duration(1, TimeUnit.SECONDS)))
val accounts = limiter(() => analytics.management().accounts().list().execute().getItems)

Maybe you are exceeding the max request per profile per second. That looks like it's set to 10 (https://developers.google.com/analytics/devguides/reporting/core/v3/limits-quotas)
回答3:
You can update the "per-user rate limit" yourself in the Developers Console, in the Quotas section.
This limit is meant to protect you from accidental usage.
