具有字节数组文件的Spring Rest Controller

Question

我正在尝试将文件内容的字节数组从angular发送到其余的api。但我禁止使用Http 403。我没有启用任何安全性。我不确定我做错了什么。我尝试了几种不同的MIME类型。以下是来自angular js的http帖子，$ scope.encoded_file具有字节数组中的文件。

$http({
  method:'POST',
  url:'http://localhost:9200/docupload',
  data:{'content':$scope.encoded_file,'name':'test','type':'pdf'},
  headers:{'Content-Type':'application/octet-stream'}
  }).success(function(){}); 
 };

DocUploadService

  @RestController
  public class DocUploadService {

  @RequestMapping(value="/docupload",method={RequestMethod.GET,RequestMethod.POST},consumes="application/octet-stream")
  public String UploadDocuments(@RequestParam(value="content")byte[] content,@RequestParam(value="type") String type,@RequestParam(value="name") String name) throws IOException
    {
        System.out.println("****Inside DocUpload*****");}}

请求当然没有达到服务，我不知道为什么我会收到403.有什么想法吗？

请求标题：

在服务方法之前添加了@CrossOrigin，但仍然没有运气

下面是否将CrossOrigin添加到控制器方法中。

public class DocUploadService {
@CrossOrigin(origins = "http://localhost:9200")
@RequestMapping(value="/docupload",method={RequestMethod.GET,RequestMethod.POST,RequestMethod.OPTIONS,RequestMethod.PUT},consumes="application/octet-stream")

此外，添加了全球CORS注册表。

 @EnableWebMvc
 public class WebMVCconfig extends WebMvcConfigurerAdapter {

 @Override
 public void addCorsMappings(CorsRegistry registry) {
    // TODO Auto-generated method stub
    registry.addMapping("/docupload")
    .allowedOrigins("http://localhost:9200")
    .allowedMethods("POST", "GET","OPTION","PUT");
    super.addCorsMappings(registry);

}

Answer 1

尝试添加过滤器以避免CORS：

   @Component
public class SimpleCORSFilter implements Filter {

    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE, PATCH");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
        response.setHeader("Access-Control-Expose-Headers", "Location");
        chain.doFilter(req, res);
    }

    public void init(FilterConfig filterConfig) {}

    public void destroy() {}

}

或者你也可以使用@CrossOrigin注释：

@CrossOrigin(origins = "http://localhost:9200")
