Laravel中使用Guzzle请求API后JSON解析错误求助

Hey there, let's break down why you're hitting that error and how to fix it:

问题根源 #

When you use $res->getBody()->getContents(), what you're getting back is a raw JSON string, not a PHP object or array. That's why trying to access ->matches directly throws an error—strings don't have object properties to access!

修复步骤 #

You need to parse the JSON string into a usable PHP structure first using json_decode():

1. Parse the JSON string
   Pick either a PHP object or associative array based on your preference:

   • To get a PHP object:

     $data = json_decode($return_values);
     

   • To get an associative array:

     $data = json_decode($return_values, true);
     

2. Access the matches data
   Now you can retrieve the matches correctly:

   • If you went with an object:

     print_r($data->matches);
     

   • If you went with an array:

     print_r($data['matches']);
     

推荐：添加错误检查 #

To avoid unexpected issues, it's smart to verify the JSON parsed successfully and that the matches field exists:

$data = json_decode($return_values);
if (json_last_error() !== JSON_ERROR_NONE) {
    echo "JSON parsing failed: " . json_last_error_msg();
} else {
    if (isset($data->matches)) {
        print_r($data->matches);
    } else {
        echo "No 'matches' field found in the API response";
    }
}
