我正在尝试使用 cURL 和 PHP 从 Clarifai 图像识别中获取标签。

在他们的网站上有一个用户指南：https://developer.clarifai.com/guide/#authentication

问题更新

我成功获取了有效的响应，看起来是这样的：

    {  "status": {    "code": 10000,    "description": "Ok"  },  "outputs": [    {      "id": "ea68cac87c304b28a8046557062f34a0",      "status": {        "code": 10000,        "description": "Ok"      },      "created_at": "2016-11-22T16:50:25Z",      "model": {        "name": "general-v1.3",        "id": "aaa03c23b3724a16a56b629203edc62c",        "created_at": "2017-08-09T17:11:39Z",        "app_id": null,        "output_info": {          "message": "Show output_info with: GET /models/{model_id}/output_info",          "type": "concept"        },        "model_version": {          "id": "aa9ca48295b37401f8af92ad1af0d91d",          "created_at": "2016-07-13T01:19:12Z",          "status": {            "code": 21100,            "description": "Model trained successfully"          }        }      },      "input": {        "id": "ea68cac87c304b28a8046557062f34a0",        "data": {          "image": {            "url": "https://samples.clarifai.com/metro-north.jpg"          }        }      },      "data": {        "concepts": [          {            "id": "ai_HLmqFqBf",            "name": "train",            "app_id": null,            "value": 0.9989112          },          {            "id": "ai_fvlBqXZR",            "name": "railway",            "app_id": null,            "value": 0.9975532          },          {            "id": "ai_VSVscs9k",            "name": "terminal",            "app_id": null,            "value": 0.9230834          }        ]      }    }  ]}

现在，我尝试遍历标签：

     $response = curl_exec($curl);     $header_size = curl_getinfo($curl, CURLINFO_HEADER_SIZE);     $body = substr($response, $header_size);     $header = substr($response, 0, $header_size);     $rows = explode("\n", $header);     $err = curl_error($curl);     curl_close($curl);     $resp = json_decode( $body, true );     if ($err) {echo $err; } else {         // 遍历标签，如果标签值高于93，则显示/输出它     }

但是我无法遍历标签，无法输出任何标签，我希望只显示值高于例如93的标签名称。

回答：

尝试：

CURLOPT_CUSTOMREQUEST => “POST”
Authorization: Key f26b16808e2a440abb5f28b1c00b6nnn (无括号)

然后

CURLOPT_POSTFIELDS => “{ \”inputs\”: [ { \”data\”: { \”image\”: { \”url\”: \”https://samples.clarifai.com/metro-north.jpg\” } } } ] }

基本上需要匹配此处 cURL 列中的格式：https://developer.clarifai.com/guide/predict#predict
