如何只提取某些句子

Question

Exception: Request failed for https://test123.my.salesforce.com returned code 400. Truncated server response: [{"message":"Use one of these records?","errorCode":"UNKNOWN_EXCEPTION","fields":[]}] (use muteHttpExceptions option to examine full response)


Exception: Request failed for https://test123.my.salesforce.com returned code 400. Truncated server response: [{"message”:”myNum: value outside of valid range on numeric field: 100.0","errorCode":"NUMBER_OUTSIDE_VALID_RANGE","fields”:[“myNum”__c]}] (use muteHttpExceptions option to examine full response)

我只想從以下句子中提取消息部分。

“使用這些記錄之一？”

”myNum：數值字段的有效范圍之外的值：100.0”

我嘗試了幾種方法，但沒有成功。

我嘗試使用 split 和 slice，錯誤消息的格式已更改，並且未正確顯示。

var response_code = error.toString();
var slice = response_code.split(':')[4]
var errormessage = (slice||'').split(',')[0]

有我想要的結果，

"Use one of these records?"

部分結果被截斷。

"myNum

我應該怎么辦？

假設 JSON 鍵"message"在您的日志語句中相對唯一，您可以使用match() ，如下所示：

 var messages = ["Exception: Request failed for https://test123.my.salesforce.com returned code 400. Truncated server response: [{\"message\":\"Use one of these records?\",\"errorCode\":\"UNKNOWN_EXCEPTION\",\"fields\":[]}] (use muteHttpExceptions option to examine full response)", "Exception: Request failed for https://test123.my.salesforce.com returned code 400. Truncated server response: [{\"message\":\"myNum: value outside of valid range on numeric field: 100.0\",\"errorCode\":\"NUMBER_OUTSIDE_VALID_RANGE\",\"fields\":[\"myNum\"__c]}] (use muteHttpExceptions option to examine full response)"]; var outputs = messages.map(x => x.match(/"message":"(.*?)"/)[1]); console.log(outputs);
