Guzzle - Elasticsearch - 批量API

Question

我試圖使用Elasticsearch Bulk API和guzzle，但我不知道正文的格式是什么。

當我用卷曲做的時候，我沒有任何問題。

curl -X POST "http://localhost:9200/hakuna/matata/_bulk" -H 'Content-Type: application/json' -d'
{"index": {}}
{"title": "Abc", "category": "Alphabet", "tags": ["premier", "alphabet"], "duration": 40}
{"index": {}}
{"title": "Def", "category": "Alphabet", "tags": ["second", "alphabet"], "duration": 50}
{"index": {}}
{"title": "Ghi", "category": "Alphabet", "tags": ["troisieme", "alphabet"], "duration": 60}
'

當我用guzzle做的時候，我總是得到這個錯誤

 Client error: `POST http://localhost:9200/hakuna/matata/_bulk` resul  
  ted in a `400 Bad Request` response:                                         
  {"error":{"root_cause":[{"type":"action_request_validation_exception","reas  
  on":"Validation Failed: 1: no requests added; (truncated...)    

這是php代碼

        $data = [
            json_encode(['index' => []]),
            json_encode(['title' => 'Abc', 'category' => 'Alphabet', 'tags' => ['premier', 'alphabet'], 'duration' => 40]),
            json_encode(['index' => []]),
            json_encode(['title' => 'Def', 'category' => 'Alphabet', 'tags' => ['second', 'alphabet'], 'duration' => 50]),
            json_encode(['index' => []]),
            json_encode(['title' => 'Ghi', 'category' => 'Alphabet', 'tags' => ['troisieme', 'alphabet'], 'duration' => 60]),
        ];

        $data = join("\n", $data);

        $response = $client->post('hakuna/matata/_bulk', [
            'headers' => ['Content-Type' => 'application/json'],
            'json' => $data,
        ]);

我嘗試過沒有json_encode且沒有字符串轉換的普通數組，但我總是得到同樣的錯誤。

編輯：最終的工作代碼

        $data = [
            json_encode(['index' => []], JSON_FORCE_OBJECT),
            json_encode(['title' => 'Abc', 'category' => 'Alphabet', 'tags' => ['premier', 'alphabet'], 'duration' => 40]),
            json_encode(['index' => []], JSON_FORCE_OBJECT),
            json_encode(['title' => 'Def', 'category' => 'Alphabet', 'tags' => ['second', 'alphabet'], 'duration' => 50]),
            json_encode(['index' => []], JSON_FORCE_OBJECT),
            json_encode(['title' => 'Ghi', 'category' => 'Alphabet', 'tags' => ['troisieme', 'alphabet'], 'duration' => 60]),
        ];

        $data = join("\n", $data);

        $response = $client->post('hakuna/matata/_bulk', [
            'headers' => ['Content-Type' => 'application/json'],
            'body' => $data."\n",
        ]);

到目前為止，你走的是正確的道路！

您現在需要做的就是在每行末尾添加換行符， 包括最后一行 ，如下所示：

    $data = [
        json_encode(['index' => []]),
        json_encode(['title' => 'Abc', 'category' => 'Alphabet', 'tags' => ['premier', 'alphabet'], 'duration' => 40]),
        json_encode(['index' => []]),
        json_encode(['title' => 'Def', 'category' => 'Alphabet', 'tags' => ['second', 'alphabet'], 'duration' => 50]),
        json_encode(['index' => []]),
        json_encode(['title' => 'Ghi', 'category' => 'Alphabet', 'tags' => ['troisieme', 'alphabet'], 'duration' => 60]),
    ];

    $data = join("\n", $data);

    $response = $client->post('hakuna/matata/_bulk', [
        'headers' => ['Content-Type' => 'application/json'],
        'body' => $data . '\n';                   <--- change this line
    ]);
