google-api-php-client - 如何在 php 中使用 Google Fit api 计算步数？

Question

我遇到了 Google Api Php Client 和 Google Fit 的问题。

我想获取一天内完成的总步数。

我找到了 a response但它不起作用(查看要点)。

我的 php 代码:

// 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 />");
     };
 }

这里的问题是它没有进入第一个 while 循环:$listDataSources->valid() returns always false。

我的问题:为什么返回 false？我怎样才能得到步数？

我尝试使用 Oauth Playground (https://www.googleapis.com/fitness/v1/users/me/dataSources/derived:com.google.step_count.delta:com.google. android.gms:estimated_steps) 但我没有得到任何数据。

我明白了:

{
    "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"
}

首先要注意的是:您使用的设备上是否有任何数据？我犯了这个错误:尝试从根本没有 Google 健身数据的帐户中获取数据。请不要重蹈我的覆辙。

我使用了与您相同的示例，它对我有用。唯一的区别是我硬编码了我的客户端 API，如下所示:

$APIKey = '1231231231231231231231231231123123';
$client_id = '12312312312-dkoasodiajsdaosdjh12h1kjakdahs.apps.googleusercontent.com';
$client_secret = '123123123-1231231-123123123';
$redirect_uri = 'http://localhost/fit/code.php';

也许您的凭据有问题。你开始你的 session 了吗？在上述代码后添加session_start()

下面的代码对我有用。适应它，我希望它能帮助你。

<?php

 * This was modified to work with Google Fit.

// 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();

$client = new Google_Client();
$client->setApplicationName('google-fit');
$client->setAccessType('online');

$client->addScope(Google_Service_Fitness::FITNESS_ACTIVITY_READ);
$service = new Google_Service_Fitness($client);
