【问题描述】:
我在 AngularJs 和 SpringBoot API REST 中有一个 webbApp。
我使用 GET 调用 API REST 来检索文本数据流并尝试将其保存在字符集为 WINDOWS-1250 的文件中。
场景:
1) AngularsJs 客户端访问 API REST
2) API REST 读取数据库,准备数据并在响应正文中返回结果
3) AngularsJS 客户端将结果保存在一个字符集为 WINDOWS-1250 的文件中。
因此,在第三部分中,我使用 FileSaver.saveAs 保存文件,但文件始终采用 UTF-8 字符集。即使我尝试在 Windows-1250 中设置字符集。
有人可以帮助我吗?
Angular 测试脚本:
$http({method:'GET',
url: $scope.url + "/cmpcode/" + this.demand.company + "/pcmcode/" + this.demand.pcmcode + "/prlcode/" + this.demand.prlcode + "/user/" + this.demand.user,
responseType : "blob" ,
headers:{'X-Auth-Token': sessionService.getLogonDatas.token}})
.then(function(response) {
$scope.showErrorAlert = false;
var data = new Blob([response.data], { type: 'text/plain; charset=Windows-1250' });
FileSaver.saveAs(data, "MyFile.test");
$scope.showSuccessAlert = true;},
function(rejection) {
$scope.showSuccessAlert = false;
if (rejection.status === 406){$scope.message.code = "NO_ROWS";}
$scope.showErrorAlert = true;});
};
SpringBoot 测试 APIREST:
public void getPaymentNationalFile(HttpServletResponse response,
@PathVariable("cmpcode") @Length(max = 12) @NotNull String companyCode,
@PathVariable("pcmcode") @Length(max = 12) @NotNull String pcmcode,
@PathVariable("prlcode") @Length(max = 12) @NotNull String prlcode,
@PathVariable("user") @Length(max = 12) @NotNull String user,
{
//Without Try & Catch
PaymentNationalParam paymentNationalParam = new PaymentNationalParam(companyCode, pcmcode, prlcode, user);
paymentNationalData = paymentNationalService.GetFilePaymentNational(paymentNationalParam);
response.setContentType("text/plain;charset=" + paymentNationalData.getCharacterEncoding()); //Here "Windows-1250"
int longueur = 0 ;
byte[] buffer = null;
ServletOutputStream servletOutputStream = response.getOutputStream();
for (String string : paymentNationalData.prepareLignePaymentToWrite())
{
buffer = (string + "\n").getBytes() ;
longueur += buffer.length;
servletOutputStream.write(buffer , 0, buffer.length);
}
response.setContentLength(longueur);
servletOutputStream.flush();
}
