如何将以下curl命令“转换”为有效的php curl函数?
curl -X POST
-F "images_file=@fruitbowl.jpg"
-F parameters=%7B%22classifier_ids%22%3A%5B%22testtype_205919966%22%5D%2C%22threshold%22%3A0%7D
'https://gateway-a.watsonplatform.net/visual-recognition/api/v3/classify?api_key={key}&version=2016-05-20'"
我似乎做错了,我无法弄清楚问题:
$method = 'POST'
$url = 'https://gateway-a.watsonplatform.net/visual-recognition/api/v3/classify?api_key=<myApiKey>&version=2016-05-20'
$data = array(
array(<file-information>),
array(<json-string>),
)
$header = array(
'Content-Type: application/json',
'Content-Length: ' . strlen(<json-string>),
)
)
public function send($method, $url, $data = null, $header = null)
{
$curl = curl_init();
switch ($method) {
case "POST":
curl_setopt($curl, CURLOPT_POST, 1);
if ($data) {
$postData = $this->renderPostData($data);
curl_setopt($curl, CURLOPT_POSTFIELDS, $postData);
}
break;
}
if($header) {
curl_setopt($curl, CURLOPT_HEADER, 1);
curl_setopt($curl,CURLOPT_HTTPHEADER,$header);
}
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($curl);
}
protected function renderPostData($data)
{
$postData = array();
foreach ($data as $file) {
if ($file['isFile']) {
if(pathinfo($file['path'], PATHINFO_EXTENSION) == 'zip'){
$postData[$file['name']] = new \CURLFile($file['path'], 'application/zip', $file['name']);
}
else {
$postData[$file['name']] = new \CURLFile($file['path'], 'application/octet-stream', $file['name']);
}
} else {
// this contains the json encoded string
$postData[$file['name']] = $file['path'];
}
}
return $postData;
}
我尝试了几种变体,现在出现了Watson Visual Recognition API错误:
{ “custom_classes”:0, “图片”: [ { “错误”:{ “description”:“图像数据无效。支持的格式为JPG和PNG。”, “error_id”:“input_error” } } ] “images_processed”:1 }
之前:
{ “错误”:{ “代码”:400, “description”:“收到无效的JSON内容。无法解析。”, “error_id”:“parameter_error” }, “images_processed”:0 }
感谢您的帮助!
答案 0 :(得分:0)
我的问题是这一行:
$postData[$file['name']] = new \CURLFile($file['path'], 'application/zip', $file['name']);
最后一个参数是$ postname。因此,要解决此问题,我必须将此行更改为:
$postData[$file['name']] = new \CURLFile($file['path'], mime_content_type($file['path']), basename($file['path']));
并且它有效 - 在我也完全删除了错误的$header
