我有以下使用 HttpClient 的代码
/**
* This method used to upload file on server with other details.
*
* @param {FormData} formData - This parameter have data about keyId, KeyValue and docCatId
* @param {string} url - This parameter contains serverside upload file Endpoint
* @memberof DocumentUploadService
*/
uploadDocument(formData: FormData, url: string): Observable <DocumentUploadResponse> {
const headers = new HttpHeaders({'Content-Type': 'multipart/form-data','Accept':'application/json','boundary':'simple-text'});
return this.http.post<DocumentUploadResponse>(url, FormData,{headers: headers});
}
FormData 对象创建如下
const formData = new FormData();
formData.append('docContent', fileList[0]);
formData.append('documentUploadDetails', JSON.stringify(this.documentUpload));
formData.append('docName',fileList[0].name);
Rest Service 写的如下
@RequestMapping(headers = ("content-type=multipart/form-data;boundary=simple-text"),method=RequestMethod.POST,produces = MediaType.APPLICATION_JSON_VALUE, consumes=MediaType.ALL_VALUE)
public ResponseEntity<DocumentUploadResponse> uploadDocument(
@RequestParam(name = "docContent", required = true) MultipartFile multipartFile,
@RequestParam(name = "documentUploadDetails", required = true) String documentUploadDetails,
@RequestParam(name = "docName", required = true) String docName)
{
LOGGER.debug("Invoked uploadDocument method");
return new ResponseEntity<>(documentUploadHandler.handleUploadDocument(multipartFile, documentUploadDetails,docName), HttpStatus.OK);
}
所以当我上传任何文件时，我收到了下面提到的错误
org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.FileUploadException: the request was rejected because no multipart boundary was found

我尝试了许多组合来传递内容类型并删除了内容类型。还尝试添加一些字段并删除标题，但在我的情况下没有任何效果
