这篇文章主要介绍了Spring boot @RequestBody数据传递过程详解,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

@RequestBody需要接的参数是一个string化的json

@RequestBody，要读取的数据在请求体里，所以要发post请求，还要将Content-Type设置为application/json

java的api

参数为JSONObject，获取到的参数处理

@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调用

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动画.pptx","1"],["E:/java/project/ppt/data/系统时间和实时天气.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调用

<?php
//初始化
$curl = curl_init();
//设置抓取的url
curl_setopt($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),
));
//执行命令
$data = curl_exec($curl);
//关闭URL请求
curl_close($curl);
//显示获得的数据
print_r($data);

（3）postman调用

参数

{"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动画.pptx","1"]]}
