我有一个数据库调用，提供有效负载，如下所述。我如何使用dataweave以示例表下面提供的格式将该有效负载转换为json？

|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|    company    |status|    license_id    |acct status|   last_inv_date   |  acctnum |      owner      | entlmt |            roles          |subscribed|attr_type|        attr_key       |attr_value|
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| company name 1|Active|02iq0000000xlBBAAY|   Active  |2016-02-25 22:50:04|A100001135|myemail@email.com|Standard|Admin;wcl_admin;wcl_support|     1    |  cloud  |cloud_num_247_t_streams|     1    |
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| company name 1|Active|02iq0000000xlBBAAY|   Active  |2016-02-25 22:50:04|A100001135|myemail@email.com|Standard|Admin;wcl_admin;wcl_support|     1    |  cloud  |      api_access       |     1    |
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| company name 1|Active|02iq0000000xlBBAAY|   Active  |2016-02-25 22:50:04|A100001135|myemail@email.com|Standard|Admin;wcl_admin;wcl_support|     1    |  cloud  |cloud_num_247_p_streams|     1    |
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| company name 2|Active|02iq0000000xlBBBBZ|   Active  |2016-02-25 22:50:04|A100001166|myblah1@email.com|Standard|           Admin           |     1    |  cloud  |cloud_num_247_p_streams|     0    |
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| company name 2|Active|02iq0000000xlBBBBZ|   Active  |2016-02-25 22:50:04|A100001166|myblah1@email.com|Standard|           Admin           |     1    |  cloud  |       api_access      |     1    |
|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

json中所需的最终输出：

{
  "records": [
    {
      "company": "company name 1",
      "has_active_subscriptions": true,
      "license_status": "Active",
      "license_id": "02iq0000000xlBBAAY",
      "account_status": "Prospect",
      "last_invoice_date": "2016-02-25 22:50:04",
      "cloud_owner_email": "myemail@email.com",
      "role": [
        "Admin",
        "wcl_admin",
        "wcl_support"
      ],
      "account_number": "A100001135",
      "attributes": {
        "cloud": {
          "api_access": 1,
          "cloud_num_247_t_streams": 1,
          "cloud_num_247_p_streams": 1
        }
      },
      "entitlement_plan": "Standard"
    },
    {
      "company": "company name 2",
      "has_active_subscriptions": true,
      "license_status": "Active",
      "license_id": "02iq0000000xlBBBBZ",
      "account_status": "Active",
      "last_invoice_date": "2016-02-25 22:50:04",
      "cloud_owner_email": "myblah@email.com",
      "role": [
        "Admin"
      ],
      "account_number": "A100001166",
      "attributes": {
        "cloud": {
          "cloud_num_247_p_streams": 0,
          "api_access": 1
        }
      },
      "entitlement_plan": "Standard"
    }
  ]
}

Answer 1

假设dataweave组件就在数据库组件之后，并且查询结果仍然在有效负载上：有效负载是CaseInsensitiveHashMap的ArrayList - 类似于JSON上的记录对象。

所以我会尝试类似的事情：

%dw 1.0
%output application/json

records: payload

如果您只想将结果集转换为JSON，则不需要DataWeave。您可以使用ObjectToJson转换器来执行此操作。
