使用DataWeave

Question

轉換爲日期格式騾子

我的要求是將字符串轉換爲騾子使用DataWeave

輸入字符串

8/30/2015 4:00:13 PM 

輸出日期必須在日期格式MM/DD/YYYY格式即

08/30/2015 

我使用下面的邏輯

(($[1] splitBy " ")[0]) as :date{format:"[m01]/[d01]/[y0001]"} 

已經嘗試

這給

Exception while executing: 
"Order Date":(($[1] splitBy " ")[0]) as :date{format:"[m01]/[d01]/[y0001]"}, 
Cannot coerce a :string to a :date                                      ^

我使用的騾子Anypoint Studio版本錯誤：5.2.0

Answer 1

您可以使用此，

var newDate = new Date("8/30/2015 4:00:13 PM"); 
var dd = newDate.getDate(); 
var mm = newDate.getMonth()+1; //January is 0! 

var yyyy = newDate.getFullYear(); 
if(dd<10){ 
    dd='0'+dd 
} 
if(mm<10){ 
    mm='0'+mm 
} 
var formattedDate = mm+'/'+dd+'/'+yyyy; 
console.log(formattedDate); //Prints "08/30/2015"

Answer 2

首先你需要將其轉換爲localdatetime（無時區），然後轉換爲所需格式的字符串。

"8/30/2015 4:00:13 PM" 
    as :localdatetime {format: "M/dd/yyyy h:mm:ss a"} 
    as :string {format: "MM/dd/yyyy"}

在DataWeave，您可以分析一個字符串以各種Java時間類型以及它們的格式返回字符串。在DataWeave日期格式

payload.date as :localdatetime {format: "M/dd/yyyy h:mm:ss a"} as :string {format: "MM/dd/yyyy"} 

Here's some more detail：嘗試解析之後的格式，像這樣。

喜在dataweave你可以寫表達這樣

formatedDate: |2003-10-01T23:57:59| as :string {format: "MM-dd-YYYY"}
