Question

我写了一个角度代码，用于从ag-grid删除多行。我通过向服务器发送请求来删除行。在删除单行时，它工作正常。但是，当我删除多行时，URL更改了（“ /”始终替换为％5C），并且出现HTTP响应错误。谁能帮我解决这个问题？这是我的代码：

DeleteFile.component.ts：

private deletePath = "http://localhost:3028/controller/removeDirectory";
  delete(){
    if(this.selectedRows.length!=0){
      for(let i=0;i<this.selectedRows.length;i++){
        this.params = new HttpParams();
        this.params = this.params.append('dir', this.selectedRows[i]);
        this.http.get(this.deletePath,{params : this.params}).subscribe( (data : any )=> {
        });
      }
      this.http.get(this.path).subscribe( // this code is to set results to an array for display ag-grid
        (data: any) => {
          this.searchResults = data;
          console.log(this.searchResults);
        },
        error => console.log(error)
      );
      this.selectedRows = [];
    }
    else{
      alert("no rows selected to delete");
    }
  }

这是控制器中的方法：

@RequestMapping(value = "/removeDirectory", method = RequestMethod.GET)
    public @ResponseBody void removeDirectory(@RequestParam("dir") String dir) {
        fileSearchProcessing.removeDirectory(dir);
    }

我得到的错误是：对于dir = C：/ Users / Acer / Desktop / Dhana / m

core.js:1633 ERROR HttpErrorResponse {headers: HttpHeaders, status: 500, statusText: "OK", url: "http://localhost:3028/controller/removeDirectory?dir=C:%5CUsers%5CAcer%5CDesktop%5CDhana%5Cm", ok: false, …}

从Ag-grid中以角度
