我正在尝试上传Angular 图像。
我执行以下步骤：
在服务中，我使用以下设置：

postFormDataToServerMultiPart(action: string, formData) {
    var headerss = new HttpHeaders({
      "Content-Type": "multipart/form-data"
    });

    return this.http
      .post(HttpService.apiUrl + action, formData, { headers: headerss })
      .pipe(map((response: any) => response));
  }

标题包含： "Content-Type": "multipart/form-data" 在component.ts中：

var formData = new FormData();
          formData.append("file", this.imageForm.get("profile").value);

          if (this.Image) {
            this.httpService
              .postFormDataToServerMultiPart(
                "api/upload/driver_image?id=" + this.employeeId,
                formData
              )
              .subscribe((resp) => {
                console.log("edit", resp);
                if (resp.status == "SUCCESS") {
                  var dialogRef = this.dialog.open(DisplayPopupComponent, {
                    data: {
                      title: "Driver Updated Successfully!",
                    },

    ............

我收到这个错误：

error: "Internal Server Error"
message: "Current request is not a multipart request"
path: "/api/upload/driver_image"
status: 500
timestamp: "2021-07-09T13:45:23.443+0000"

我做错了什么？
小姐怎么了？
