Angular 下载zip文件并重命名文件

后端Java代码需要设置response的header，如下

response.setContentType("application/octet-stream; charset=utf8");
response.setHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_OCTET_STREAM_VALUE);
response.setHeader(HttpHeaders.CONTENT_DISPOSITION,"attachment; filename="+zipName);

Angular/Typescript需要使用File类来重命名

download() {

const token = localStorage. getItem(' token');

let headers: HttpHeaders = new HttpHeaders();

headers = headers

. set(' Authorization', ' Bearer ' + token);

const url = 'http://localhost:8764/api/v1/user/downLoadZipFile';

this. http. get( url, {headers: headers, observe: ' response', responseType: ' blob'}). subscribe( response => {

console. log( response);

console. log( response.headers. keys());

this. downloadFile( response);

}, ( error: HttpErrorResponse) => {

console. log( error. error);

});

}

downloadFile( data: HttpResponse< Blob>) {

const file = new Blob([ data.body], {type: ' application/zip'});

const a = document. createElement(' a');

a.id = ' tempId';

document.body. appendChild( a);

a. download = ' haha.zip';

a.href = URL. createObjectURL( file);

a. click();

const tempA = document. getElementById(' tempId');

if ( tempA) {

tempA.parentNode. removeChild( tempA);

}

 

}

}

 关于File类，可以参考以下文档
