利用映射集函数，可在源架构和目标架构之间转换数据。您可以使用/languages/el端点来验证表达式，并获得所有可用映射集函数的列表。

验证表达式

您可以通过向/languages/el/validate端点发出POST请求来验证当前表达式是否有效。

API格式

POST /languages/el/validate

请求

curl -X POST https://platform.adobe.io/data/foundation/conversion/languages/el/validate \
  -H 'Authorization: Bearer {ACCESS_TOKEN}' \
  -H 'Content-Type: application/json' \
  -H 'x-api-key: {API_KEY}' \
  -H 'x-gw-ims-org-id: {ORG_ID}' \
  -H 'x-sandbox-name: {SANDBOX_NAME}' \
  -d '
  {
    "expression": "concat(\"Hi\", \",\", \"there\", \"!\")"
  }'

响应

成功的响应会返回HTTP状态200以及表达式的验证状态。

{
    "validationStatus": "succeeded",
    "error": "none"
}

列表映射集函数

通过向/languages/el/functions端点发出GET请求，您可以检索所有可用的映射集函数的列表。

API格式

GET /languages/el/functions

请求

curl -X GET https://platform.adobe.io/data/foundation/conversion/languages/el/functions \
  -H 'Authorization: Bearer {ACCESS_TOKEN}' \
  -H 'x-api-key: {API_KEY}' \
  -H 'x-gw-ims-org-id: {ORG_ID}' \
  -H 'x-sandbox-name: {SANDBOX_NAME}'

响应

成功的响应会返回HTTP状态200，其中包含所有可用映射集函数的列表。

列表映射集运算符

通过向/languages/el/operators端点发出GET请求，您可以检索所有可用的映射集运算符的列表。

API格式

GET /languages/el/operators

请求
