spring boot @RequestBody数据传递及解析

@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

//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"]]}
