为什么Spring Boot不接受我的Axios POST请求？

Question

我正在尝试使用Axios将带有JSON正文的POST请求发送到Spring引导应用程序。但是，Spring启动应用程序返回Required request body is missing:。

当我向邮递员发送相同的请求时，它确实可以正常工作。

我有一个非常简单的控制器：

@RestController
 @RequestMapping(value = "/deployments")
   public class DeploymentController {
     @PostMapping
     public ResponseEntity<Deployment> createDeployment(@RequestBody Deployment deployment) {
       //DoStuff
     }
   }

我发布的正文在两种情况下都是相同的：

{
  "name": "testdeployment2",
  "domainName": "domain.local",
  "repository": "KB",
  "branch": "master",
  "servicepack": "6.5.1"
}

当我向邮递员发送请求时，请求看起来像：

{
  "args": {}, 
  "data": "{\"name\":\"testdeployment2\",\"domainName\":\"domain.local\",\"repository\":\"KB\",\"branch\":\"master\",\"servicepack\":\"6.5.1\"}", 
  "files": {}, 
  "form": {}, 
  "headers": {
    "Accept": "*/*", 
    "Accept-Encoding": "gzip, deflate, br", 
    "Cache-Control": "no-cache", 
    "Content-Length": "129", 
    "Content-Type": "application/json", 
    "Host": "httpbin.org", 
    "Postman-Token": "238d83b0-1f14-4828-abf5-45978a80c008", 
    "User-Agent": "PostmanRuntime/7.22.0", 
    "X-Amzn-Trace-Id": "Root=1-5e6221c7-9be7dcc1163e105cd3495bf8"
  }, 
  "json": {
    "branch": "master", 
    "domainName": "domain.local", 
    "name": "testdeployment2", 
    "repository": "KB", 
    "servicepack": "6.5.1"
  }, 
  "origin": "IP", 
  "url": "http://httpbin.org/post"
}

Axios代码：

const url = 'http://httpbin.org/post';
const options = {
  headers: {
    'Content-Type' : 'application/json'
  }
};

this.$http.post(
  url,
  this.form,
  options
).then(result => {
  this.result = result;
}).catch(error => {
  alert(error);
});

并且Axios请求看起来像：

{
  "args": {},
  "data": "{\"name\":\"testdeployment2\",\"domainName\":\"domain.local\",\"repository\":\"KB\",\"branch\":\"master\",\"servicepack\":\"6.5.1\"}",
  "files": {},
  "form": {},
  "headers": {
    "Accept": "application/json, text/plain, */*",
    "Accept-Encoding": "gzip, deflate",
    "Accept-Language": "en-US,en;q=0.9,nl;q=0.8",
    "Content-Length": "129",
    "Content-Type": "application/json",
    "Dnt": "1",
    "Host": "httpbin.org",
    "Origin": "http://localhost:8080",
    "Referer": "http://localhost:8080/",
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36",
    "X-Amzn-Trace-Id": "Root=1-5e6223c7-35d5028ab672229267f65e9c"
  },
  "json": {
    "branch": "master",
    "domainName": "domain.local",
    "name": "testdeployment2",
    "repository": "KB",
    "servicepack": "6.5.1"
  },
  "origin": "IP",
  "url": "http://httpbin.org/post"
}

这里有什么我没看到的东西吗？为什么Postman可以工作，而Axios不能工作？

所以我完全忘记了在API方面检查CORS。在我的控制器方法上允许所有CORS之后，它现在可以工作了。 h！
