js傳遞數組到後臺

今天一位同事碰到了這個問題,相互討論了下,記錄下備忘
方法一:
1.使用JSON.stringify 將數組對象轉化成json字符串;
var array = ["1", "2"];
$.ajax({
type : ‘POST‘,
url: path + ‘/check/testPost‘,
contentType : "application/json" ,
data : JSON.stringify(array),
success : function(data) {
}
});
2.傳輸過程中參數
3.後臺處理
@RequestMapping(value = "/testPost", method = {RequestMethod.POST})
public void testPost(@RequestBody String[] array) throws IOException {
for (String string : array) {
System.out.println(string);
}
return ;
}
方法二:
1.前端不做處理:
var array = ["1", "2"];
$.ajax({
type : ‘POST‘,
url: path + ‘/check/testPost‘,
contentType: "application/x-www-form-urlencoded",
data: {"array": array},
success : function(data) {
}
});
2.傳輸過程中參數
3.後臺處理
@RequestMapping(value = "/testPost", method = {RequestMethod.POST})
public void testPost(HttpServletRequest req) throws IOException {
String[] array = req.getParameterValues("array[]");
for (String string : array) {
System.out.println(string);
}
return ;
}
註:兩種post請求的content-type不同。
