问题
I got a problem with the Google Api Php Client and Google Fit.
I want to get the sum of steps I made in a day.
I found a response but it doesn't work (look at the gist).
My php code:
// Retrive oauth data
$clientData = json_decode(file_get_contents("../Devbook-87e2bafd84e6.json"));
$client_email = $clientData->client_email;
$private_key = $clientData->private_key;
$scopes = array(Google_Service_Fitness::FITNESS_ACTIVITY_READ);
$credentials = new Google_Auth_AssertionCredentials(
$client_email,
$scopes,
$private_key
);
$client = new Google_Client();
$client->setState('offline');
$client->setRedirectUri('urn:ietf:wg:oauth:2.0:oob'); // Used in hybrid flows
$client->setAssertionCredentials($credentials);
if ($client->getAuth()->isAccessTokenExpired()) {
$client->getAuth()->refreshTokenWithAssertion();
}
$fitness_service = new Google_Service_Fitness($client);
$dataSources = $fitness_service->users_dataSources;
$dataSets = $fitness_service->users_dataSources_datasets;
$listDataSources = $dataSources->listUsersDataSources("me");
$timezone = "GMT+0100";
$today = date("Y-m-d");
$endTime = strtotime($today.' 00:00:00 '.$timezone);
$startTime = strtotime('-1 day', $endTime);
while($listDataSources->valid()) {
$dataSourceItem = $listDataSources->next();
if ($dataSourceItem['dataType']['name'] == "com.google.step_count.delta") {
$dataStreamId = $dataSourceItem['dataStreamId'];
$listDatasets = $dataSets->get("me", $dataStreamId, $startTime.'000000000'.'-'.$endTime.'000000000');
$step_count = 0;
while($listDatasets->valid()) {
$dataSet = $listDatasets->next();
$dataSetValues = $dataSet['value'];
if ($dataSetValues && is_array($dataSetValues)) {
foreach($dataSetValues as $dataSetValue) {
$step_count += $dataSetValue['intVal'];
}
}
}
print("STEP: ".$step_count."<br />");
};
}
The problem here is it didn't enter in the first while loop : $listDataSources->valid() returns always false.
My question : Why it returns false ? And how can I get steps ?
I tried to retrieve data with the Oauth Playground (https://www.googleapis.com/fitness/v1/users/me/dataSources/derived:com.google.step_count.delta:com.google.android.gms:estimated_steps) but I didn't get any data.
I got this :
{
"dataType": {
"field": [{
"name": "steps",
"format": "integer"
}],
"name": "com.google.step_count.delta"
},
"application": {
"packageName": "com.google.android.gms",
"version": ""
},
"dataStreamId": "derived:com.google.step_count.delta:com.google.android.gms:estimated_steps",
"type": "derived",
"dataStreamName": "estimated_steps"
}

First things first: Do you have any data at all on the device that you're using? I've made that mistake: try to get data from an account with no Google Fit data at all. Don't repeat my mistake, please.
I used the same example as you and it worked for me. The only difference is that I hard coded my client API, like this:
$APIKey = '1231231231231231231231231231123123';
$client_id = '12312312312-dkoasodiajsdaosdjh12h1kjakdahs.apps.googleusercontent.com';
$client_secret = '123123123-1231231-123123123';
$redirect_uri = 'http://localhost/fit/code.php';
Maybe you're having problems with your credentials.
Did you start your session? Add a session_start() after the code above.
The code below is working for me. Adapt it and I hope it helps you.
<?php
/*
* This code is an adaptation of Google API URL Shortener example from Google PHP API github.
* This was modified to work with Google Fit.
* This example will count steps from a logged in user.

// I created an Autoloader to load Google API classes
require_once(__DIR__ . '/Autoloader.php');
$APIKey = '1231231231231231231231231231123123';
$client_id = '12312312312-dkoasodiajsdaosdjh12h1kjakdahs.apps.googleusercontent.com';
$client_secret = '123123123-1231231-123123123';
$redirect_uri = 'http://localhost/fit/code.php';
//This template is nothing but some HTML. You can find it on github Google API example.
include_once "templates/base.php";
//Start your session.
session_start();
