Question

我正在编写一个Angular项目，并从我写了球衣的服务器上获取HTTP请求。

我已经准备了一个管理页面，可以通过该页面执行CRED操作。

当我执行一个动作时，我得到一个错误（好像操作失败了），并报告一条消息，说明操作成功。我写的服务器上的某些内容可能导致了这种情况。

Angular服务器上的功能：

  public addCompany(newCompanyName:String, newCompanyPassword:String, newCompanyEmail:String ){
    let newP:any ={
      "name": newCompanyName,
      "password": newCompanyPassword,
      "email": newCompanyEmail,
      "coupons": []
      };

     this.myHttpClient.post<any>("http://localhost:8080/CouponSystemJersey/couponsystem/admin/insertCompany",newP).subscribe(
       (res)=>{console.log("new company")},
       (err)=>{console.log(err)}
       ); 
  }

服务器功能：

@POST
    @Path("insertCompany")
    @Consumes(MediaType.APPLICATION_JSON)
    public Response insertCompany(Company company) {
        try {
            getFacaed().insertCompany(company);
        } catch (CompanyAlreadyExistsException | SystemMalfunctionException e) {
            return Response.status(Response.Status.INTERNAL_SERVER_ERROR).entity(e.getMessage()).build();
        }
        return Response.ok("A new customer was inserted").build();
    }

错误消息：

HttpErrorResponse {headers: HttpHeaders, status: 200, statusText: "OK", url: "http://localhost:8080/CouponSystemJersey/couponsystem/admin/insertCompany", ok: false, …}

尽管操作成功，但在执行CRED操作后出现错误
