Question

下面代码中的错误是什么？它返回以下错误：

{ "error":"Internal server error (root cause: multipart\/form-data; boundary=----------------------------248f475465f9)",
  "code":404 }

代码：

<?php
     function testLangID($data) {
         $curl = curl_init();

         $headers_arr = array(
            "contentItems" =>  array(
                "userid" => "dummyuserid",
                "id" => "dummyid",
                "sourceid" => "freetext",
                "contenttype" => "application/json",
                "language" => "en",
                "content" => $data
            ) 
        );

         curl_setopt($curl, CURLOPT_POST, true);  
         curl_setopt($curl, CURLOPT_POSTFIELDS, $headers_arr);
         curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
         curl_setopt($curl, CURLOPT_USERPWD, "........:........");
         curl_setopt($curl, CURLOPT_URL, "https://gateway.watsonplatform.net/personality-insights/api");
         curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

         $result = curl_exec($curl); 

         curl_close($curl);

         $decoded = json_decode($result, true);

         return $result;
    }


    if ($_SERVER["REQUEST_METHOD"] == "POST") {  
        $res= testLangID( $_POST["textLID"] ); 
        echo $res;
    }

?>

Answer 1

您正在使用的url：

curl_setopt($curl, CURLOPT_URL, "https://gateway.watsonplatform.net/personality-insights/api");

应该是：

curl_setopt($curl, CURLOPT_URL, "https://gateway.watsonplatform.net/personality-insights/api/v2/profile");

我看到你用的是contentItems，你也可以把content-type: text/plain和text发送到正文中，不需要构建JSON对象。在正文中发送text的curl命令是：

curl -X POST -u USERNAME:PASSWORD \
-H "Content-Type: text/plain" \
-d "Text to analyze" \
"https://gateway.watsonplatform.net/personality-insights/api/v2/profile"

今天早上早些时候，我在dwAnswers上回答了这个问题。

您只需要在POST请求中使用"body“参数(如果不使用默认值，则需要"headers”)。正如API文档中所述，其他参数是HTTP HEADER请求的一部分。

以下是为使用Watson Personality Insights而修改的PHP代码：

     $curl = curl_init();
     $post_args = array(
          'body' => $data
     );
     $header_args = array(
         'Content-Type: text/plain',
         'Accept: application/json'
     );
     curl_setopt($curl, CURLOPT_POST, true);
     curl_setopt($curl, CURLOPT_POSTFIELDS, $post_args);
     curl_setopt($curl, CURLOPT_HTTPHEADER, $header_args);
     curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
     curl_setopt($curl, CURLOPT_USERPWD,<user id>:<password>");
     curl_setopt($curl, CURLOPT_URL, "https://gateway.watsonplatform.net/personality-insights/api/v2/profile");
     curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

     $result = curl_exec($curl);

     curl_close($curl);

     $decoded = json_decode($result, true);
