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"]]}
