使用php和curl不斷發布“缺少內容流”錯誤，以發布XML

Question

當維基文章的內容更改時，我試圖讓php發布到solr服務器。 這是SOLR版本4.4.0，PHP 5.3.3，CURL 7.19.7。

有人有什么想法嗎？ 謝謝，皮特。

這是PHP代碼

$header = array("Content-Type: text/xml; charset=UTF-8");

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://wiki.XXXXX.com:8080/solr/update?wt=json&indent=true");        
curl_setopt($ch, CURLOPT_HEADER, $header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,  $encoded);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLINFO_HEADER_OUT, 1);
$result = curl_exec($ch);

這是錯誤

Answer 1

從帖子到Solr的“缺少內容流”意味着您向Solr發送了空文檔或根本沒有發送文檔。 在這種情況下，您似乎正在嘗試更新Solr中的某些內容-但是根據此錯誤，您沒有進行任何傳遞。 我也看不到您的代碼中包含或指向要更新的文檔的任何內容-

這些先前的討論可能會有所幫助：

SolrCore中“缺少內容流”異常的重要性是什么？

Answer 2

盡管此解決方案之前已在評論中給出，但我想在此處的單獨答案中予以強調。

Solr顯然會在沒有提交的請求上返回“缺少內容流”。 對於實際給出的內容文件，返回的錯誤令人困惑。

我正在分析使用Solarium客戶端執行extractOnly請求的類似情況。 在嘗試切換客戶端適配器並確保請求包括所選文件之后，我終於通過添加$request->setCommit( true );成功了$request->setCommit( true ); 。
