我遇到了這個錯誤,我知道它期待一個對象,並且已經通過論壇進行搜索,嘗試應用修復時失敗,這可能是一個簡單的修復通過幾行代碼。我欣賞是否有人有一點時間來幫助解決這個問題。php調用成員函數sentimentAnalysis()非對象
同樣,這可能是重複的,但我曾嘗試應用修復未成功
錯誤與下面的線,我會包括我的整個腳本
$response= $TwitterSentinmentAnalysis->sentimentAnalysis($twitterSearchParams);

這是它從TwitterSentimentAnalysis.php調用函數的文件
public function sentimentAnalysis($twitterSearchParams) {
$tweets=$this->getTweets($twitterSearchParams);
return $this->findSentiment($tweets);
}
