spring boot @RequestBody數據傳遞及解析

@RequestBody需要接的參數是一個string化的json

@RequestBody，要讀取的數據在請求體里，所以要發post請求，還要將Content-Type設置為application/json

java的api

  參數為JSONObject，獲取到的參數處理

    @PostMapping("/combine")
    public Result combine(@RequestBody JSONObject jsonParam) { System.out.println(jsonParam.toJSONString()); System.out.println(jsonParam.get("fileName")); ArrayList ll= (ArrayList)jsonParam.get("ops"); for(int i = 0;i < ll.size(); i ++){ ArrayList mm = (ArrayList)ll.get(i); for(int j = 0;j < mm.size(); j ++){ System.out.println(mm.get(j)); } } return ResultGenerator.genSuccessResult(); }

（1）js調用

var  dispatchesDTO = {"fileName":"E:/java/project/ppt/data/tmpTest.pptx","ops":[["E:/java/project/ppt/data/test1.pptx","1,2,9"],["E:/java/project/ppt/data/Threejs動畫.pptx","1"],["E:/java/project/ppt/data/系統時間和實時天氣.pptx","1"]]};
$.ajax({
        type: "post",  
        contentType:"application/json",  
    url: "http://localhost:8080/api/ppt/combine",  
    data: JSON.stringify(dispatchesDTO),  
    success: function(data){  
        console.log(data);  
    }
});

（2）php的curl調用

<?php
//初始化
$curl = curl_init();
//設置抓取的url
curl_setopt($curl, CURLOPT_URL, 'http://localhost:8080/api/ppt/combine');
$aa = [
    "fileName" => "E:/java/project/ppt/data/tmp.pptx",
    "ops"      => [['E:/java/project/ppt/data/test1.pptx', '1,2,9'],
        ['E:/java/project/ppt/data/test1.pptx', '2'],
    ],
];
$data_string = json_encode($aa);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($curl, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Content-Length: ' . strlen($data_string),
));
//執行命令
$data = curl_exec($curl);
//關閉URL請求
curl_close($curl);
//顯示獲得的數據
print_r($data);

（3）postman調用

參數

{"fileName":"E:/java/project/ppt/data/tmpTest.pptx","ops":[["E:/java/project/ppt/data/test1.pptx","1,2,9"],["E:/java/project/ppt/data/Threejs動畫.pptx","1"]]}
