我想使用 Watson 的 Personality Insight Service 来分析用户的推文。我正在使用 PHP 进行编码。这是我用来从 Twitter API 获取推文并将它们输入到 watson 的 PI 服务中的代码块。
//Watson PI Parameters
$pi_url = 'https://gateway.watsonplatform.net/personality-
insights/api/v3/profile?version=2016-10-20';
$pi_username = 'XXXX';
$pi_password = 'YYYY';
// auth parameters
$api_key = urlencode('API KEY'); // Consumer Key
$api_secret = urlencode('API Secret'); // Consumer Secret
$auth_url = 'https://api.twitter.com/oauth2/token';
// Twitter Data Parameters
$data_username = 'Screen Name'; // username
$data_count = 10; // number of tweets
$data_url = 'https://api.twitter.com/1.1/statuses/user_timeline.json?
tweet_mode=extended';
// get api access token
$api_credentials = base64_encode($api_key.':'.$api_secret);
$auth_headers = 'Authorization: Basic '.$api_credentials."\r\n".
'Content-Type: application/x-www-form-urlencoded;charset=UTF-
8'."\r\n";
$auth_context = stream_context_create(
array(
'http' => array(
'header' => $auth_headers,
'method' => 'POST',
'content'=> http_build_query(array('grant_type' =>
'client_credentials', )),
)
)
);
$auth_response = json_decode(file_get_contents($auth_url, 0,
$auth_context), true);
$auth_token = $auth_response['access_token'];
// get tweets
$data_context = stream_context_create( array( 'http' => array( 'header' =>
'Authorization: Bearer '.$auth_token."\r\n", ) ) );
$data = file_get_contents($data_url.'&count='.$data_count.
'&screen_name='.urlencode($data_username), 0, $data_context);
print_r($data);
// Pass $data as input to PI
$ch = curl_init();
// Sets the URL cURL will open
curl_setopt($ch, CURLOPT_URL, $pi_url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
)
);
// Here's the HTTP auth
curl_setopt($ch, CURLOPT_USERPWD, $pi_username." : ".$pi_password);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_CAINFO, getcwd() . "\CertificateLocation");
// Makes curl_exec() return server response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// And here's the result JSON
$response = curl_exec($ch);
print curl_error($ch);
curl_close($ch);
print_r($response);
我收到 { "code": 400, "sub_code": "S00005", "error": "Invalid JSON input at line 4, column 28" } 错误。
有人可以帮助我如何预先格式化我的 Twitter 响应，以便 PI 可以将其识别为 Json 输入并对其进行分析。
编辑：
添加推特结果作为答案，因为评论太长了。这是我使用 Amazon twitter 句柄得到的结果（尝试这个只是为了测试）
