如何将IBM Watson cURL命令转换为PHP

我需要在PHP中转换这个cURL命令，以便在我的WordPress站点上使用它

curl -X POST -F "images_file=@fruitbowl.jpg" -F "parameters=@fruit.json" "https://gateway-a.watsonplatform.net/visual-recognition/api/v3/classify?api_key={api-key}&version=2016-05-20"

我正在使用的参数对象：

{
    "classifier_ids": [
        "My_Model_ID",
        "default"
    ],
    "owners": ["me"],
    "threshold": 0.6
}

这是我的尝试：

<?php
//Here is the JSON Parameters Object
$arr = array('classifier_ids' => array('My_Model_ID', 'default'), 'owners' => array('me'), 'threshold' => 0.6);

//Here is the endpoint URL
$url = 'https://gateway-a.watsonplatform.net/visual-recognition/api/v3/classify?api_key=MY_KEY&version=2016-05-20';

// IMPORTANT - Image that is uploaded on my site 
$filename = file_get_contents('@/wp-content/uploads/2018/03/raiox_img02.jpg');
$cfile = curl_file_create($filename,'image/jpeg');

//cURL
$ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url); //URL
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    //curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    curl_setopt($ch, CURLOPT_POST, 1); //POST
    curl_setopt($ch, CURLOPT_FILE, $cFile); //Try pass image
    curl_setopt($ch, CURLOPT_POSTFIELDS,  json_encode($arr)); //Try pass JSON

//Result
$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Erro: ' . curl_error($ch); //Error
}
curl_close ($ch); //Finish

echo $result;

<?php

// Code Date: March, 2018
// === Remember to see all documentation in IBM Watson ===

// Set the endpoint URL
$url = 'https://gateway-a.watsonplatform.net/visual-recognition/api/v3/classify?api_key={your_api_key}&version=2016-05-20';

// Set the image url
$image_url = '&url=http://completeURL.com/img.jpg';

// Set my custom classifier
$classifier = '&classifier_ids={your_custom_model_ID}';

// Set the Threshold, by default is 0.5 - To show all scores use Zero
$threshold = '&threshold=0';

//cURL
$ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url); //Endpoint URL
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1); //POST
    curl_setopt($ch, CURLOPT_POSTFIELDS, $image_url . $classifier . $threshold); //Parameters

// Execute the cURL command
$result = curl_exec($ch);

// Erro
if (curl_errno($ch)) {
    echo 'Error: ' . curl_error($ch);
}

// Close the command
curl_close ($ch);

// Show the JSON result
echo $result;

这是我返回的JSON：

{
 "error":
     {
       "code": 400,
       "error_id": "input_error",
       "description": "No images were specified."
     },
 "images_processed": 0
}

我想使用我的IBM Watson视觉识别自定义模型。 我留下了关于我如何使用它的评论，因为我使用的语法无法使用我需要的图像

使用WordPress

版本：9.4.4

插件：

我使用以下链接来指导我：

请记住，我没有安装任何库或使用Composer。

经过几次尝试，我能够使用IBM Watson Visual Recognition的自定义分类器模型使代码正常工作

将

{your_api_key}

更改为您的凭证，将

{your_custom_model_ID}

更改为您的自定义model ID

代码：

<?php
//Here is the JSON Parameters Object
$arr = array('classifier_ids' => array('My_Model_ID', 'default'), 'owners' => array('me'), 'threshold' => 0.6);

//Here is the endpoint URL
$url = 'https://gateway-a.watsonplatform.net/visual-recognition/api/v3/classify?api_key=MY_KEY&version=2016-05-20';

// IMPORTANT - Image that is uploaded on my site 
$filename = file_get_contents('@/wp-content/uploads/2018/03/raiox_img02.jpg');
$cfile = curl_file_create($filename,'image/jpeg');

//cURL
$ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url); //URL
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    //curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    curl_setopt($ch, CURLOPT_POST, 1); //POST
    curl_setopt($ch, CURLOPT_FILE, $cFile); //Try pass image
    curl_setopt($ch, CURLOPT_POSTFIELDS,  json_encode($arr)); //Try pass JSON

//Result
$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Erro: ' . curl_error($ch); //Error
}
curl_close ($ch); //Finish

echo $result;

<?php

// Code Date: March, 2018
// === Remember to see all documentation in IBM Watson ===

// Set the endpoint URL
$url = 'https://gateway-a.watsonplatform.net/visual-recognition/api/v3/classify?api_key={your_api_key}&version=2016-05-20';

// Set the image url
$image_url = '&url=http://completeURL.com/img.jpg';

// Set my custom classifier
$classifier = '&classifier_ids={your_custom_model_ID}';

// Set the Threshold, by default is 0.5 - To show all scores use Zero
$threshold = '&threshold=0';

//cURL
$ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url); //Endpoint URL
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1); //POST
    curl_setopt($ch, CURLOPT_POSTFIELDS, $image_url . $classifier . $threshold); //Parameters

// Execute the cURL command
$result = curl_exec($ch);

// Erro
if (curl_errno($ch)) {
    echo 'Error: ' . curl_error($ch);
}

// Close the command
curl_close ($ch);

// Show the JSON result
echo $result;

你确定
/wp content/uploads/2018/03/raiox_img02.jpg文件存在，还是你用正确的路径调用它？另外，下一个错误用法是
curl_file_create（）
函数。你的
$filename=file_get_contents（'@/wp content/uploads/2018/03/raiox_img02.jpg'）文件在哪里代码定位？这就是问题所在，我如何使用此图像？首先，回答我的问题，您的文件位于哪里（包含您提供的文档的文件）？乐意帮助。很高兴你为即将到来的人找到了解决方案，并且想让detect_faces方法发挥作用，我在这里留下了这样做的要点（受此答案启发）
