Flutter Airtable Data [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: Exception: 422
当我尝试更新 Airtable 数据库的某些数据时，出现 [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: Exception: 422。
我可以获取、删除但无法更新我的数据。

更新
- 不要把你的 id 放在 Url
- 将Content-Type放入headers
- 更改您的 body 以传递记录，并更新 id + 字段
没有用你的确切结构测试，所以告诉我...
Future<AirtableDataCandidate> updateCandidate(String id, String match) async {
final response = await http.put(
Uri.https(
"api.airtable.com", "/v0/${Config.airtableProjectBase}/candidat/", /* 1 */

headers: {
"Authorization": "Bearer ${Config.airtableApikey}",
"Content-Type": "application/json", /* 2 */
},
body: jsonEncode( /* 3 */
{
"records": [
{
"id": $id,
"fields": {
'match': match,
}
},
]
},
),
)
/// etc.
插入（供参考）
- 在POST
- 不要使用 ID...
- 列出您所有的字段...
