通过PHP将文档添加到Apache Solr cURL

Question

我不知道我做错了什么。该记录不会被添加。

这里是我的代码：

$ch = curl_init("http://127.0.0.1:8983/solr/collection1/update/json?commit=true"); 

$data = array(
    "add" => array("doc" => array(
     "id" => "HW132", 
     "name" => "Hello World" 
    )) 
); 
$data_string = json_encode($data); 

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
curl_setopt($ch, CURLOPT_POST, TRUE); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json')); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); 

$response = curl_exec($ch); 

这里是我从Solr的得到响应：

{"responseHeader":{"status":0,"QTime":4}}

很显然，我需要问Apache Solr实现以提交文件。它不会自动提交文档，也可能我不知道如何配置它来自动提交。以下是工作示例。希望它能帮助那些有同样问题的人。

$ch = curl_init("http://127.0.0.1:8983/solr/collection1/update?wt=json"); 

$data = array(
    "add" => array( 
     "doc" => array(
      "id" => "HW2212", 
      "title" => "Hello World 2" 
     ), 
     "commitWithin" => 1000, 
    ), 
); 
$data_string = json_encode($data); 

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
curl_setopt($ch, CURLOPT_POST, TRUE); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json')); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); 

$response = curl_exec($ch);

所以不太清楚你用的是什么版本的Solr，3.X或4.X（但它们在如何处理与提交不同，但将涵盖）。无论哪种情况，这些都是您可以在solrconfig.xml文件中进行的更改

对于3.x，您可以在多个文档或毫秒数或两者中指定自动提交。打门槛后的Solr将提交更改，所以你不必在你的代码：

<!-- autocommit pending docs if certain criteria are met. Future versions may expand the available 
    criteria --> 
    <autoCommit> 
     <maxDocs>10000</maxDocs> <!-- maximum uncommited docs before autocommit triggered --> 
     <maxTime>15000</maxTime> <!-- maximum time (in MS) after adding a doc before an autocommit is triggered --> 
     <openSearcher>false</openSearcher> <!-- SOLR 4.0. Optionally don't open a searcher on hard commit. This is useful to minimize the size of transaction logs that keep track of uncommitted updates. --> 
    </autoCommit> 

对于4.X你也有SoftCommit选项。这使得同步到磁盘之前，可供搜索的变化：

<!-- SoftAutoCommit 

     Perform a 'soft' commit automatically under certain conditions. 
     This commit avoids ensuring that data is synched to disk. 

     maxDocs - Maximum number of documents to add since the last 
        soft commit before automaticly triggering a new soft commit. 

     maxTime - Maximum amount of time in ms that is allowed to pass 
        since a document was added before automaticly 
        triggering a new soft commit. 
     --> 

    <autoSoftCommit> 
     <maxTime>1000</maxTime> 
    </autoSoftCommit> 

我发现，思考和通在solrconfig.xml中实施这些设置，而不是依赖于应用程序代码级提交使得一个更可预测的结果。

我想发布一个XML，但我不知道下面的作品，为什么解决方案。该文件说，我应该使用'@'加文件路径上传文件，但它没有任何工作。所以，我没有这样：

<?php 

$url = 'http://localhost:8080/solr/update/?commit=true'; 
$file = realpath('/home/fabio/target_file.xml'); 

$header = array(
    "Content-Type: text/xml", 
); 

$post = file_get_contents($file); 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_HTTPHEADER, $header); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
curl_setopt($ch, CURLOPT_POST, TRUE); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $post); 
curl_setopt($ch, CURLOPT_VERBOSE, TRUE); 

echo curl_exec($ch); 
curl_close($ch); 

而且我得到这个确定（200）状态：

* Connected to localhost (127.0.0.1) port 8080 (#0)
