如何在php中使用Google Fit api获取步骤计数? [英] How to get steps count with Google Fit api in php ?

问题描述

我遇到了 Google Api Php客户端和 Google Fit 的问题.

我想获得一天完成的步骤总数.

我找到了回应，但它不起作用(请看要点).

I found a response but it doesn't work (look at the gist).

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在第一个while循环中输入: $ listDataSources-> valid() 返回总是 false

The problem here is it didn't enter in the first while loop : $listDataSources->valid() returns always false.

我的问题:为什么它返回false?以及如何获取步骤?

我试图在Oauth游乐场( https://www.googleapis.com/fitness/v1/users/me/dataSources/derived:com.google.step_count.delta:com.google.android.gms:estimated_steps )，但我没有任何数据.

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.

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"
}

推荐答案

第一件事:您正在使用的设备上是否有任何数据?我犯了一个错误:尝试从完全没有Google Fit数据的帐户中获取数据.请不要重复我的错误.

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.

我使用了与您相同的示例，它对我有用.唯一的区别是我对客户端API进行了硬编码，如下所示:

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';

也许您的凭证有问题.您开始会议了吗?在上面的代码之后添加 session_start().

Maybe you're having problems with your credentials. Did you start your session? Add a session_start() after the code above.

以下代码对我有用.对其进行调整，希望对您有所帮助.

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();

$client = new Google_Client();
$client->setApplicationName('google-fit');
$client->setAccessType('online');
$client->setApprovalPrompt("auto");
$client->setClientId($client_id);
$client->setClientSecret($client_secret);
$client->setRedirectUri($redirect_uri);

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