如何使用PHP从cURL获取json [英] How to get json from cURL with PHP

问题描述

我正在尝试使用php将cURL解码的json解码为:

I'm trying to decode a json obtening by cURL with php like this :

$url = 'https://www.toto.com/api/v1/ads/?apikey=titi&code_postal='.$code_postal.'&type_de_bois='.$type_bois;
$cURL = curl_init();
curl_setopt($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);

var_dump(json_decode($result, true));
echo json_decode($result);

那让我回想起，似乎是json:

That returns me that, something which seems to be json :

[{"id":"6918"，"nom":"X"，"code_postal":"88120"，"ville":"town"，"description":"test"，"logo":"test.png，" url:" test，"电话:true}， [{{id:" 6919，" nom:" Y，" code_postal:" 88121，" ville:" town1，" description:" test，" logo:" test.png ，" url:" test，"电话:true}， [{{"id":"6920"，"nom":"Z"，"code_postal":"88122"，"ville":"town2"，"description":"test"，"logo":"test.png ，" url:" test，"电话:true}]

[{"id":"6918","nom":"X","code_postal":"88120","ville":"town","description":"test","logo":"test.png","url":"test","telephone":true}, [{"id":"6919","nom":"Y","code_postal":"88121","ville":"town1","description":"test","logo":"test.png","url":"test","telephone":true}, [{"id":"6920","nom":"Z","code_postal":"88122","ville":"town2","description":"test","logo":"test.png","url":"test","telephone":true}]

int(1)1

我的问题是: -为什么在没有回显或打印的情况下打印数组? -为什么json_decode无法正常工作，或者为什么它只是一个值("1")?

My question are : - Why, without echo or print, the array is printed? - Why json_decode doesn't work propely or why it is only one value ("1")?

非常感谢您的回答.

推荐答案

您忘记了使用CURLOPT_RETURNTRANSFER选项.因此，curl_exec()会打印响应，而不是将其返回到$result中，并且$result仅包含TRUE所返回的值TRUE，以指示该响应已成功.添加:

You forgot to use the CURLOPT_RETURNTRANSFER option. So curl_exec() printed the response instead of returning it into $result, and $result just contains the value TRUE that was returned by curl_exec to indicate that it was successful. Add:

curl_setopt($cURL, CURLOPT_RETURNTRANSFER, true);
