我的代码:

$imageurl = "https://...imageurl.jpg";

$data = array(
    "language" => "ger",
    "isOverlayRequired" => false,
    "detectOrientation" => true,
    "scale" => true,
    "filetype" => 'JPG',
    "url" => $imageurl,
    // "base64Image" => "data:image/jpeg;base64,".base64_encode( file_get_contents($imageurl) ),
);

$ch = curl_init();

curl_setopt_array($ch, array(
    CURLOPT_URL => "https://api.ocr.space/parse/image",
    CURLOPT_RETURNTRANSFER => true, // receive server response
    CURLOPT_POST => 1, // do post
    CURLOPT_HTTPHEADER => array('Content-Type:application/json', 'apikey:MYAPIKEY'),
    CURLOPT_POSTFIELDS => json_encode($data),
));

$result = curl_exec($ch);

curl_close($ch);

$result_array = json_decode($result);

if(!empty($result_array->ErrorMessage))
{
    // catch errors https://docs.mathpix.com/#errors
    echo 'Problem: '.$result_array->ErrorMessage[0];
}

总是导致:

问题:没有上传文件,也没有提供URL或base64

我试过了 url 和 base64Image ,但还是同样的问题。

--

"No file uploaded or URL provided" when calling ocr.space API 表示必须读取和发布文件内容。不过,我很确定 网址

谢谢你的帮助(见评论)。

问题是:

请勿使用 json_encode()
将内容类型更改为 Content-Type:multipart/form-data
"false" 和 "true"

现在可以使用:

$imageurl = "https://...imageurl.jpg";

$data = array(
    "language" => "ger",
    "isOverlayRequired" => "false",
    "detectOrientation" => "true",
    "scale" => "true",
    "filetype" => 'JPG',
    "url" => $imageurl,
);

$ch = curl_init();

curl_setopt_array($ch, array(
    CURLOPT_URL => "https://api.ocr.space/parse/image",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => 1,
    CURLOPT_HTTPHEADER => array('Content-Type:multipart/form-data', 'apikey:apikey:MYAPIKEY'),
    CURLOPT_POSTFIELDS => $data,
));

$result = curl_exec($ch);

curl_close($ch);

$result_array = json_decode($result);

if(!empty($result_array->ErrorMessage))
{
    // catch errors https://docs.mathpix.com/#errors
    echo 'Problem: '.$result_array->ErrorMessage[0];
}
else 
{
    // recognized text
    $ocrresult = $result_array->ParsedResults[0]->ParsedText;
}
