Angular 6 无法读取 HttpClient 中的 Octet-stream 错误消息:"Http failure during parsing for..."

Angular 6 Unable to read Octet-stream in HttpClient Error message: "Http failure during parsing for..."

我想使用 angular 6 HttpClient (@angular/common/http) 向服务器发出非 json 请求以获取 Octet-stream 。下面是我的代码。

getFile(file: any) {
    let headers: new HttpHeaders({
        'Content-Type':  'application/octet-stream',
        'Accept':'application/octet-stream',
        'Authorization': 'Bearer ' + data.token
    })

    return this.http.get<any>(this.baseUrl + '/getfile/'+file, headers);
}

但这给了我 JSON 解析错误。

"HttpErrorResponse", message: "Http failure during parsing for..... ERROR {…} ​ error: {…} ​​ error: SyntaxError: "JSON.parse: unexpected character at line 1 column 1 of the JSON data"

非json怎么读?

试试这个:

let headers = new HttpHeaders({
    'Authorization': 'Bearer ' + data.token
    });
return this.http.get<any>(this.baseUrl + '/getfile/'+file, {headers:headers, responseType: 'blob'});
