cURL의 JSON 응답 처리

Question

내가 사용하는 주소 확인 API에서 데이터를 가져 오려고하고 있으며 데이터를 가져 오는 데 문제가 있습니다. 나는 주소를 cURLing하고 응답을 얻는 데 아무런 문제가 없지만 응답을 처리하는 PHP에 도움이 필요하다.

JSON 구조 :

[ 
    { "input_index": 0, 
    "candidate_index": 0, 
    "addressee": "Apple Inc", 
    "delivery_line_1": "1 Infinite Loop", 
    "delivery_line_2": "PO Box 42", 
    "last_line": "Cupertino CA 95014-2083", 
    "delivery_point_barcode": "950142083017", 
    "metadata": { 
     "latitude":"48.12685", 
     "longitude":"-39.16847" 
    }, 
    } 
    { "input_index": 1, 
    "candidate_index": 0, 
    "addressee": "Google Inc", 
    "delivery_line_1": "1600 Amphitheater Pkwy", 
    "delivery_line_2": "", 
    "last_line": "Mountain View CA 94043-1351", 
    "delivery_point_barcode": "950142083017", 
    "metadata": { 
     "latitude":"48.12685", 
     "longitude":"-39.16847" 
    }, 
    } 
] 

내 코드 :

$response = curl_exec($ch); 
curl_close($ch); 
$rd = json_decode($response); 

echo $rd->metadata[0]->latitude; 

그러나 나는 Trying to get property of non-object의 오류가 발생합니다.

내가 뭘 잘못하고 있니?

편집 :

인 print_r ($의 RD); 저를 제공합니다

Answer 1

잘못된 JSON :

"metadata": { 
    "latitude":"48.12685", 
    "longitude":"-39.16847 
} ... 

가 있어야한다 :

"metadata": { 
    "latitude":"48.12685", 
    "longitude":"-39.16847" 
} ... 

마음 경도 값에 닫는 ".

또한, 두 항목은 ,으로 구분해야합니다 마지막으로

[ 
    { "input_index": 0, 
    ... 

    }, 


    { "input_index": 1, 
    ... 
    } 
] 

: 당신이 얻을 것은 객체의 배열입니다 -하지 배열로 객체 : 무엇을

$rd[0]->metadata->latitude ...
