我正在查询输出json的第三方服务。
$data = json_decode($result,true);
var_dump ($data);
$ data认为:
{"response":{"status":"OK","token":"hbapi:187089:586e655ed1f9c:nym2","dbg_info":{"instance":"53.bm-hbapi.prod.ams1","slave_hit":false,"db":"master","parent_dbg_info":{"instance":"64.bm-hbapi.prod.nym2","slave_hit":false,"db":"master","parent_dbg_info":{"instance":"45.bm-api.prod.nym2","slave_hit":false,"db":"master","time":664.07299041748,"version":"1.17","warnings":[],"slave_lag":0,"start_microtime":1483629917.8571},"awesomesauce_cache_used":false,"count_cache_used":false,"uuid":"39e1c17a-7fe4-58ac-9486-c4dd5bbf96a3","warnings":[],"time":1159.7349643707,"start_microtime":1483629917.7835,"version":"1.17.150","slave_lag":0,"output_term":"not_found"},"awesomesauce_cache_used":false,"count_cache_used":false,"uuid":"286ca4bc-6964-50ad-b241-ff9df1304278","warnings":[],"time":1347.2578525543,"start_microtime":1483629917.6534,"version":"1.17.150","slave_lag":0,"output_term":"not_found","master_instance":"64.bm-hbapi.prod.nym2","proxy":true,"master_time":1159.7349643707}}}
我正在尝试获取令牌值。
我试过
$token = $data["response"][0]["token"];
我得到了空白
我也试过
$token = $data['response'][0]['token'];
我仍然得到NULL。
我看过How can I access an array/object?和其他线索 - 无法找到问题。

$token = $data["response"]["token"];
JSON:
{
"response": {
"status": "OK",
"token": "hbapi:187089:586e655ed1f9c:nym2",
"dbg_info": {
}
}
}

$data
是一个对象(不是数组),因此您可以访问response
作为此对象的属性:$data->response
。
response
又是一个对象。等。
例如status
可以这样调用:$data->response->status
。
您可以使用以下代码查看什么是对象以及什么是数组:
print "<pre>";
var_dump($data);
所以在你的情况下,要获得token
:
$token = $data->response->token
答案 2 :(得分:0)
如果不是数组,为什么要访问pos [0]?
而不是尝试访问所需的参数,如下所示:
$token = $data["response"]["token"];
答案 3 :(得分:0)
将$data['response'][0]['token'];
更改为$data['response']['token'];
$ data ['response']是,它没有0索引。
{
"status": "OK",
"token": "hbapi:187089:586e655ed1f9c:nym2",
"dbg_info": {
}

在$ data中你仍然有json,所以你应该再次调用json_decode($ data)。
