如何使用 PHP 解析 Google Fit Json 字符串

Question

Am trying to parse a response i get from GoogleFit API. Here is the snippet i wrote:

1 $result = curl_exec($ch);//execute post
2 curl_close($ch);//close connection 
3 $newResult = json_encode($result); 
4 Log::info($newResult); 
5 return $newResult;

And the response looks like this:

{ "access_token": "ya29.Il-4B1111", "token_type": "Bearer", "expires_in": 3600, "refresh_token": "1//09uJO5Lo7CFhyCg3333", "scope": "https://www.googleapis.com/auth/fitness.activity.read https://www.googleapis.com/auth/fitness.location.read" } true

Line 4 is Logging instead of the response.

true

I want to store access_token , refresh_token , and expires_in in my db . I cant access the properties of the response either. Please help

Answer 1

You can decode/parse the JSON response in the following ways:

1. object
2. PHP associative array

for the second option, use true in json_decode()

ie you can use following:

<?php
const NL = PHP_EOL;

$json = '{
    "access_token": "ya29.Il-4B1111",
    "token_type": "Bearer",
    "expires_in": 3600,
    "refresh_token": "1//09uJO5Lo7CFhyCg3333",
    "scope": "https://www.googleapis.com/auth/fitness.activity.read https://www.googleapis.com/auth/fitness.location.read"
}';

// object
$jsonObj = json_decode($json);
echo $jsonObj->access_token;
echo NL;
echo $jsonObj->refresh_token;
echo NL;
echo $jsonObj->expires_in;
echo NL;

// associative array
$jsonArr = json_decode($json, true);
echo $jsonArr['access_token'];
echo NL;
echo $jsonArr['refresh_token'];
echo NL;
echo $jsonArr['expires_in'];

Answer 2

Some APIs respond with an invalid JSON. They add an boolean expression (true or 1) after the JSON object for security reasons. You might have to prehandle the response by yourself before parsing.

Answer 3

I assume you are encoding the $result for your logging. After that, you can use json_decode($newResult, true) - which basically converts this into an array and you can get the relevant values you need.

https://www.php.net/manual/en/function.json-decode.php

Answer 4

$url = 'YOUR API URL GOES HERE';

$cURL = curl_init();

curl_setopt($cURL, CURLOPT_URL, $url);
curl_setopt($cURL, CURLOPT_HTTPGET, true);

curl_setopt($cURL, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Accept: application/json'
));

$result = curl_exec($cURL);

curl_close($cURL);   

$json = json_decode($result, true);
print_r($json);

OUTPUT

Array
(
    [access_token] => ya29.Il-4B1111
    [token_type] => Bearer
    //....
)

Now you can work with $json variable as an array:

echo $json['access_token'];
echo $json['token_type'];
