Question

如何使用PHP获取JSON格式的Deeplinks？

这是我实际拥有的JSON对象

    $i=1;       
    foreach($data->webPages->value as $val){
        if($i==1){
            $part   = $val['deepLinks']->snippet;
        }   
    $i++;       
    }

这是我到目前为止所做的代码：

Fatal error: Cannot use object of type stdClass as array.

结果：@testable import YOUR_MODULE_NAME class MyViewControllerTests: XCTestCase { var myVC : MyViewController! }

如何获得该值？

Answer 1

我认为这可能与$ data有关。它不是数组。

您是否使用json_decode（）将JSON对象转换为PHP变量？如果是，那么您需要将其更改为：

 json_decode($myJSON, true);

如果设置为true，PHP将返回一个关联数组，但如果不是PHP，它将返回一个对象（stdClass）。

您可以详细了解原因here

如果你想要一个平面的深度链接数组，试试这个：

$ret = [];
foreach($data->webPages->value as $val){
    if(property_exists($val,"deepLinks")){
        $ret = array_merge($ret, $val->deepLinks);
    }
}
var_dump($ret);

我测试了它并且有效。

另一方面，如果你想把它分组：

$ret = [];
foreach($data->webPages->value as $val){
    if(property_exists($val,"deepLinks")){
        $ret[] = $val->deepLinks;
    }
}
var_dump($ret);

我使用的测试JSON：

$data = '{
    "_type": "SearchResponse",
    "webPages": {
        "webSearchUrl": "https:\/\/www.bing.com\/cr?IG=B470EF0A41D94B338002992668141CC5&CID=1B1D0110A94966F5383E0B4AA8A067DE&rd=1&h=sFk5GtkV8PxaqVq0K3GniaQOQJqKR2jqw1udftLC9QE&v=1&r=https%3a%2f%2fwww.bing.com%2fsearch%3fq%3dcontemporary%2bfurniture&p=DevEx,5336.1",
