使用带有模式的PHPAPI在BigQuery中创建表

我正在尝试使用PHPAPI在bigquery中创建一个表

我可以创建一个没有模式的表，但是当我提供一个模式时，会出现错误。看起来我使用了错误的语法，但是我尝试了我能想到的任何格式，却找不到一个我试图实现的示例

我使用字符串文字作为fields参数进行测试。我的代码如下所示：

    $bigQuery = new BigQueryClient([
        'keyFilePath' => [keyfilepath],
        'projectId' => [projectid],
        'location' => [location]
    ]);

    /** @var Dataset $dataSet */
    $dataSet = $bigQuery->dataset('my-data-set');

    $fieldString = '{"name": "myfield","type": "STRING","mode": "REQUIRED"}' . "\n" . '{"name": "anotherfield", "type": "STRING", "mode": "REQUIRED"}';
    $options = [
        'fields' => $fieldString
    ];
    $dataSet->createTable('mytable', $options);

$fieldString = '[{"name": "myfield","type": "STRING","mode": "REQUIRED"}, {"name": "anotherfield", "type": "STRING", "mode": "REQUIRED"}]';

    $fields = [
        ['name'=> 'myfield', 'type' => 'INTEGER', 'mode' => 'REQUIRED'],
        ['name'=> 'anotherfield', 'type' => 'INTEGER', 'mode' => 'REQUIRED']
    ];
    $options = [
        'fields' => $fields
    ];
    $dataSet->createTable('mytable', $options);

 $fields = [
    [
        'name' => 'field1',
        'type' => 'string',
        'mode' => 'required'
    ],
    [
        'name' => 'field2',
        'type' => 'integer'
    ],
];

这就产生了错误：

无效的字段选择{\'name\：\'myfield\'

或者，当我格式化“$fieldString”时，如下所示：

    $bigQuery = new BigQueryClient([
        'keyFilePath' => [keyfilepath],
        'projectId' => [projectid],
        'location' => [location]
    ]);

    /** @var Dataset $dataSet */
    $dataSet = $bigQuery->dataset('my-data-set');

    $fieldString = '{"name": "myfield","type": "STRING","mode": "REQUIRED"}' . "\n" . '{"name": "anotherfield", "type": "STRING", "mode": "REQUIRED"}';
    $options = [
        'fields' => $fieldString
    ];
    $dataSet->createTable('mytable', $options);

$fieldString = '[{"name": "myfield","type": "STRING","mode": "REQUIRED"}, {"name": "anotherfield", "type": "STRING", "mode": "REQUIRED"}]';

    $fields = [
        ['name'=> 'myfield', 'type' => 'INTEGER', 'mode' => 'REQUIRED'],
        ['name'=> 'anotherfield', 'type' => 'INTEGER', 'mode' => 'REQUIRED']
    ];
    $options = [
        'fields' => $fields
    ];
    $dataSet->createTable('mytable', $options);

 $fields = [
    [
        'name' => 'field1',
        'type' => 'string',
        'mode' => 'required'
    ],
    [
        'name' => 'field2',
        'type' => 'integer'
    ],
];

我得到一个错误：

无效的字段掩码“[{name\”：“myfield\”，“type\”：“STRING\”，“mode\”：“REQUIRED\”，{\“name\”：“anotherfield\”，“type\”：“STRING\”，“mode\”：“REQUIRED\”）。映射键应表示为[\“some\ u key\”]

我还尝试先创建表，然后像这样更新它：

$table = $dataSet->createTable('mytable');
$table->update($options);

但是我得到了同样的错误，即使我使用json表示法，问题仍然存在

我做错了什么

更新：

实际上，在我切换到字段的字符串文字之前，我首先尝试了这一点：

    $fields = [
        ['name'=> 'myfield', 'type' => 'INTEGER', 'mode' => 'REQUIRED'],
        ['name'=> 'anotherfield', 'type' => 'INTEGER', 'mode' => 'REQUIRED']
    ];
    $options = [
        'schema' => $fields
    ];
    $dataSet->createTable('mytable', $options);

这将产生以下错误：

接收到无效的JSON负载。“表”中的未知名称“架构”：Proto字段未重复，无法启动列表

然后我将代码编辑成如下所示：

    $bigQuery = new BigQueryClient([
        'keyFilePath' => [keyfilepath],
        'projectId' => [projectid],
        'location' => [location]
    ]);

    /** @var Dataset $dataSet */
    $dataSet = $bigQuery->dataset('my-data-set');

    $fieldString = '{"name": "myfield","type": "STRING","mode": "REQUIRED"}' . "\n" . '{"name": "anotherfield", "type": "STRING", "mode": "REQUIRED"}';
    $options = [
        'fields' => $fieldString
    ];
    $dataSet->createTable('mytable', $options);

$fieldString = '[{"name": "myfield","type": "STRING","mode": "REQUIRED"}, {"name": "anotherfield", "type": "STRING", "mode": "REQUIRED"}]';

    $fields = [
        ['name'=> 'myfield', 'type' => 'INTEGER', 'mode' => 'REQUIRED'],
        ['name'=> 'anotherfield', 'type' => 'INTEGER', 'mode' => 'REQUIRED']
    ];
    $options = [
        'fields' => $fields
    ];
    $dataSet->createTable('mytable', $options);

 $fields = [
    [
        'name' => 'field1',
        'type' => 'string',
        'mode' => 'required'
    ],
    [
        'name' => 'field2',
        'type' => 'integer'
    ],
];

警告：rawurlencode（）要求参数1为字符串，数组给定

我以前在问题中没有提到这一点，因为我认为它不相关。事后看来可能是这样，但我的问题仍然存在。没有

$fieldString

这类东西，即

$fields

数组

像这样：

    $bigQuery = new BigQueryClient([
        'keyFilePath' => [keyfilepath],
        'projectId' => [projectid],
        'location' => [location]
    ]);

    /** @var Dataset $dataSet */
    $dataSet = $bigQuery->dataset('my-data-set');

    $fieldString = '{"name": "myfield","type": "STRING","mode": "REQUIRED"}' . "\n" . '{"name": "anotherfield", "type": "STRING", "mode": "REQUIRED"}';
    $options = [
        'fields' => $fieldString
    ];
    $dataSet->createTable('mytable', $options);

$fieldString = '[{"name": "myfield","type": "STRING","mode": "REQUIRED"}, {"name": "anotherfield", "type": "STRING", "mode": "REQUIRED"}]';

    $fields = [
        ['name'=> 'myfield', 'type' => 'INTEGER', 'mode' => 'REQUIRED'],
        ['name'=> 'anotherfield', 'type' => 'INTEGER', 'mode' => 'REQUIRED']
    ];
    $options = [
        'fields' => $fields
    ];
    $dataSet->createTable('mytable', $options);

 $fields = [
    [
        'name' => 'field1',
        'type' => 'string',
        'mode' => 'required'
    ],
    [
        'name' => 'field2',
        'type' => 'integer'
    ],
];

然后

参见示例。

谢谢你的回答。这实际上是我尝试的第一件事，但我收到的错误似乎很明显，我没有提及。我已经用添加的示例更新了我的问题，你介意看一下吗？再次检查模式->字段->你的数组符号。你没有设置“模式”键的行。就是这样。Tha这个问题很好地说明了为什么异常应该有有用的消息。它开始于我在“table”中阅读“Unknown name\”schema\“并认为“这个键显然有错误的名称”。
