我正在嘗試顯示來(lái)自此https://pomber.github.io/covid19/timeseries.json的 JSON 數(shù)據(jù)，但出現(xiàn)錯(cuò)誤：(ErrorException(code: 0): Undefined index: confirmed我期望的是我可以顯示國(guó)家名稱(chēng)列表以及日期、確認(rèn)等。這是我的看法：@foreach($results as $json_d) {{ $json_d['date'] }} {{ $json_d['confirmed'] }} {{ $json_d['deaths'] }} {{ $json_d['recovered'] }}@endforeach這是我的控制器：$client = new Client();$request = $client->get('https://pomber.github.io/covid19/timeseries.json');$response = $request->getBody()->getContents();$results = json_decode($response, true);return view('dashboard', compact('results'));任何幫助，將不勝感激 ：）

您使用 Guzzle 獲得的結(jié)果是國(guó)家/地區(qū)列表
dd($results);
給
array:152 [▼
"Thailand" => array:57 [?]
"Japan" => array:57 [?]
"Singapore" => array:57 [?]
"Nepal" => array:57 [?]
"Malaysia" => array:57 [?]
"Canada" => array:57 [?]
"Australia" => array:57 [?]
"Cambodia" => array:57 [?]
"Sri Lanka" => array:57 [?]
"Germany" => array:57 [?]
"Finland" => array:57 [?]

這意味著您需要另一個(gè)循環(huán)
@foreach($results as $countryData)
@foreach($countryData as $data)
{{ $data['date'] }}
{{ $data['confirmed'] }}
{{ $data['deaths'] }}
{{ $data['recovered'] }}
@endforeach
@endforeach
