在javascript(或其他服务端语言), 往7牛官方上传地址(http://upload.qiniu.com/), 提交上传后, 返回值大概如下:
{"hash":"Fn1Fxzactt76AaJdn9F4XQAkBkmp","key":"e12c391016.mp4","persistentId":"z0.5b5ed2c838b9f324a52d1e31","avinfo_duration":"7.170578"}
那怎么通过这返回值的值: hash/key/persistentId 取得上传的真正链接地址呢?
其实很简单, web访问地址就是: 空间域名+文件名(key值)
拿上面的例子,假如我的7牛空间域名是:https://video.xxxxx.com
最终的链接为:https://video.xxxxx.com/e12c391016.mp4
就是这么简单, 不需要通过hash/id 请求接口去取真实地址这么麻烦.
注意: key值是可以自定义的, 直接上代码(angular版本的上传), 注意key是自己提供的参数, 所以你需要自己处理唯一性. 例子直接写死了
for (let i = 0; i < files.length; i++) {
const formData = new FormData();
formData.append('file', files[i]);
formData.append('key', "12c391016.mp4");//自定义key值
formData.append('token', this.uptoken);
this.loading = true;
const request = new HttpRequest(
'POST', this.upHost , formData,
{reportProgress: true});
this.http.request(request)
.retry(3)
.subscribe(
event => {
if (event.type === HttpEventType.UploadProgress) {
this.loading = true;
this.percentDone = Math.round(100 * event.loaded / event.total);
this.progress = `File is ${this.percentDone}% uploaded.`;
} else if (event instanceof HttpResponse) {
this.progress = `${event.body['key']} is uploaded`;
}});
this.loading = false;
}
