使用 php 和 curl 发布 XML 时不断收到“缺少内容流”错误

Question

当 wiki 文章的内容发生变化时，我试图让 php 发布到 solr 服务器。这是 SOLR 版本 4.4.0、PHP 5.3.3、CURL 7.19.7。

有人有什么想法吗？ 谢谢， 皮特。

这是 PHP 代码

$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);

这是错误

Answer 1

虽然之前在 cmets 中已经给出了这个解决方案，但在这里我想在单独的答案中强调它。

Solr 显然会在提供文件而不提交的请求上返回“丢失的内容流”。返回的错误令人困惑，因为实际上给出了内容文件。

我正在分析使用 Solarium 客户端执行 extractOnly 请求的类似案例。在尝试切换客户端适配器并确保请求包含所选文件后，我终于成功添加了$request->setCommit( true );。

Answer 2

到 Solr 的帖子中“缺少内容流”意味着您向 Solr 发送了一个空文档或根本没有文档。在这种情况下，您似乎正在尝试更新 Solr 中的某些内容 - 但是根据此错误，您没有传递任何内容。我也没有在您的代码中看到任何包含或指向要更新的文档的内容 -

这些先前的讨论可能会有所帮助：
