[英]While uploading file getting error as boundary not found when content-type sent as “multipart/form-data”.How to solve this error?
[英]missing content-type boundary when uploading IFormFile with Content-Type multipart/form-data
我有這個代碼將文件上傳到aspnet core Api
[HttpPost]
[Produces(typeof(MissionBalanceWithMissionBalanceLinesModel))]
public async Task<IActionResult> UploadBalance(IFormFile upload)
{
return Ok("successfully uploaded");
}
和角度代碼
const file: File = event.target.files[0];
const upload= new FormData();
fileToUpload.append('upload', file, file.name);
const blob = fileToUpload as any
let options_ : any = {
body: blob,
observe: "response",
responseType: "blob",
headers: new HttpHeaders({
/* "Content-Type": "multipart/form-data", */
"Accept": "text/plain"
})
};
return this.http.request("post", url_, options_)...
錯誤: System.IO.InvalidDataException:缺少內容類型邊界。
注釋/* "Content-Type": "multipart/form-data", */
行有幫助,但由於這是 NswagStudio 生成的代碼,我想找到另一個解決方法。
或者如何告訴 NswagStudio 不要生成這個 Content-Type 標頭?
您應該盡量避免請求方法使用 Post 方法。 你可以在這里查看文檔
addHero (hero: Hero): Observable<Hero> {
return this.http.post<Hero>(this.heroesUrl, hero, httpOptions)
.pipe(
catchError(this.handleError('addHero', hero))
);
}
所以你的代碼應該是
const httpOptions = {
headers: new HttpHeaders({
'Content-Type': 'multipart/form-data'
})
};
return this.http.post(url, fileToUpload, httpOptions)
