Creating an Object and Defining Fields

Scenarios

You can create a VehicleType object and define fields to store vehicle types and type IDs.

The following describes how to call the APIs for creating an object and defining fields. For details, see Calling APIs.

Creating an Object

1. Determine the request based on the actual request URI and method.

   POST https://Huawei Cloud Astro Zero domain name/u-route/baas/metadata/v1.0/object

2. Set the request header.

   Table 1 Request header

   Header Field	Description	Mandatory
   Content-Type	Parameter defined in the HTTP protocol, which identifies the format for parsing the returned content. This parameter must be set to application/json, indicating that the browser parses the returned content into a JSON object.	Yes
   access-token	When a user login request is authenticated, the backend generates a token, which is contained in the response and saved in the browser. When the user sends a request to Astro Zero, the token will be carried, indicating that the user has been authenticated.	Yes

3. Construct the message body.

   {
       "label": "VehicleType",
       "name": "VehicleType__CST",
       "description": "",
       "fields": [
           {
               "label": "Name",
               "name": "name",
               "dataType": "Name"
           }
       ],
       "view": {
           "ObjectDetailLayout": {
               "name": "__layout__VehicleType__CST__detail",
               "fields": [
                   "name"
               ]
           },
           "ObjectRecordsLayout": {
               "name": "__layout__VehicleType__CST__records",
               "fields": [
                   "name"
               ]
           }
       }
   }

   If the following response is returned, the object is created. Record the value cust000000aHYAsrPh4K of result, which is the object ID.

   {
       "resCode": "0",
       "resMsg": "Success",
       "result": "cust000000aHYAsrPh4K"
   }

Defining Fields

1. Determine the request based on the actual request URI and method. cust000000aHYAsrPh4K is the object ID.

   POST https://Huawei Cloud Astro Zero domain name/u-route/baas/metadata/v1.0/object/cust000000aHYAsrPh4K/fields

2. Set the request header.

   Table 2 Request header

   Header Field	Description	Mandatory
   Content-Type	Parameter defined in the HTTP protocol, which identifies the format for parsing the returned content. This parameter must be set to application/json, indicating that the browser parses the returned content into a JSON object.	Yes
   access-token	When a user login request is authenticated, the backend generates a token, which is contained in the response and saved in the browser. When the user sends a request to Astro Zero, the token will be carried, indicating that the user has been authenticated.	Yes

3. Construct the request body that carries the VehicleType and VehicleNumber fields.

   {
       "fields": [
           {
               "label": "VehicleType",
               "name": "VehicleType__CST",
               "dataType": "text",
               "dataLength": 255,
               "caseSensitive": false,
               "isRequired": false,
               "isUnique": false,
               "isSearchable": false
           },
           {
               "label": "VehicleNumber",
               "name": "VehicleNumber__CST",
               "dataType": "text",
               "dataLength": 255,
               "caseSensitive": true,
               "isRequired": false,
               "isUnique": true,
               "isSearchable": false
           }
       ]
   }

   If the following response is returned, the fields are created:

   {
       "resCode": "0",
       "resMsg": "Success",
       "result": [
           "cust000000aHaE6S3mim",
           "cust000000aHaE6TlNVA"
       ]
   }
