我尝试将数组数组和字符串插入到FormData中，但是java似乎没有接收到它，我的Java服务器中没有日志错误，但是我的JavaScript控制台中有一个500内部服务器错误。
下面是我的控制器的代码：
@RequestMapping(value = "/getReporting", method = RequestMethod.POST)
@ResponseBody
public void getReporting(@RequestParam RecommendationForm form, @RequestParam String type, HttpServletResponse response) throws ApcException {
System.out.println("prova");
Map.Entry<String, byte[]> result = this.reportingService.getReporting(form,type);
try {
response.setHeader(//
"Content-Disposition",//
"attachment; filename=" +"bobo.xlsx");
response.setContentType("Application/x");
response.getOutputStream().write(result.getValue());
response.flushBuffer();
} catch (IOException e) {
e.printStackTrace();
}
}
}这是我在Angular中的服务：
public getExcel(form: FormData): Observable<HttpResponse<Blob>> {
return this.http.post('/SV-AUD/api/reporting/getReporting', form, {observe: 'response', responseType: 'blob'});
}以及我在formData中附加信息的组件：
form: FormGroup = this._fb.group(
{
hello1: [],
hello2: [],
hello3: [],
hello4: [],
hello5: [],
hello6: [],
hello7: [],
hello8: [],
hello9: [],
}
);
exportExcel() {
const formData: FormData = new FormData();
formData.append('form', this.form.getRawValue());
if (this.detailedType) {
formData.append('type', 'detailed');
} else {
formData.append('type', 'list');
}
this.reportingService.getExcel(formData).subscribe(data => {
const ctHeader = data.headers.get('content-disposition');
if (ctHeader) {
const filename = ctHeader.split('=')[1];
saveAs(data.body, filename);
}
});
