Fileupload - Endpoint and OpenAI Generation for the Service

题意：文件上传 - 服务的端点和OpenAI生成

问题背景：

My Endpoint is a RestConroller with a Post-Method looking like this:

我的端点是一个带有 Post 方法的 RestController，如下所示

@PostMapping(path = "/xetra", consumes =  {MediaType.APPLICATION_JSON_VALUE,MediaType.MULTIPART_FORM_DATA_VALUE})public @ResponseBody void importXetra(@RequestParam("file") MultipartFile file) {

After OpenAI Generator i get the following signature for the endpoint:

使用 OpenAI 生成器后，我得到的端点签名如下

public importXetra(importXetraRequest?: ImportXetraRequest, observe?: 'body', reportProgress?: boolean, options?: {httpHeaderAccept?: undefined, context?: HttpContext}): Observable<any>;
public importXetra(importXetraRequest?: ImportXetraRequest, observe?: 'response', reportProgress?: boolean, options?: {httpHeaderAccept?: undefined, context?: HttpContext}): Observable<HttpResponse<any>>;
public importXetra(importXetraRequest?: ImportXetraRequest, observe?: 'events', reportProgress?: boolean, options?: {httpHeaderAccept?: undefined, context?: HttpContext}): Observable<HttpEvent<any>>;
public importXetra(importXetraRequest?: ImportXetraRequest, observe: any = 'body', reportProgress: boolean = false, options?: {httpHeaderAccept?: undefined, context?: HttpContext}): Observable<any> {

with

export interface ImportXetraRequest { 
file: Blob;
}

My formular looks like:        我的表单如下：

<p-fileUpload name="myfile[]" [customUpload]="true" (uploadHandler)="upload($event)">
<ng-template pTemplate="toolbar"><div class="py-1">Upload 1 Files</div>
</ng-template>
<ng-template let-file pTemplate="file"><div>Custom UI to display a file</div>
</ng-template>

my upload implementation:        我的上传实现

upload (event : {files: Blob[]}) : void {
let file  = event.files[0] as File;
let request: ImportXetraRequest = ({} as any) as ImportXetraRequest;
request.file = file;
this.importEndpoint.importXetra(request).subscribe({next : (res : void) => console.log("imported"),error: (e: ErrorEvent) => console.error("error = " + e),
});
}

I don't know how exactly i can do the call to the backend, the backend says it is not a valid request. I get a 500-error. It also seems that the payload is not set/empty.

我不确定如何正确地调用后端，后端提示请求无效。我收到一个500错误。似乎负载没有设置或为空

问题解决：

The problem was, that the endpoint didn't have the correct MediaType Consumer:

问题在于，该端点没有正确的MediaType Consumer

@PostMapping(path = "/xetra", consumes =  {MediaType.MULTIPART_FORM_DATA_VALUE,
})

solved the problem.        解决了问题
