Question

我想使用Angular-4将视频上传到azure blob存储，并且它可以在除IE之外的所有浏览器中正常工作

SCRIPT7002：XMLHttpRequest：网络错误0x80070005，访问被拒绝。

我正在使用put blob方法上传视频，这是它的代码。我搜索了此错误，发现了许多解决方案，但在这里不起作用我尝试过但未起作用的某些链接

Prevent IE11 caching GET call in Angular 2

  upload(config: UploadConfig) {
    debugger;
    var options = new RequestOptions();
    if (options == null) {
        options = new RequestOptions();
    }

    const state = this.initializeState(config);
    const reader = new FileReader();
    reader.onloadend = (evt: any) => {
        if (evt.target.readyState === 2 && !state.cancelled) {
            debugger;
            const uri = state.fileUrl + '&comp=block&blockid=' + state.blockIds[state.blockIds.length - 1];
            const requestData = evt.target.result;
            options.headers = new Headers();
            const requestData2 = new Uint8Array(evt.target.result);
            options.headers.append('x-ms-blob-type', 'BlockBlob');
            options.headers.append('Content-Type', 'application/octet-stream');

            this.http.put(uri, requestData, options).retryWhen(error => {
                return error
                    .flatMap((error: any) => {
                        if (error.status === 503) {
                            return Observable.of(error.status).delay(1000)
                        }
                        return Observable.throw({ error: 'No retry' });
                    })
                    .take(5)
                    .concat(Observable.throw({ error: 'Sorry, there was an error (after 5 retries)' }));
            })
                .subscribe(elem => {
                    state.bytesUploaded += requestData2.length;
                    const percentComplete = ((state.bytesUploaded / state.file.size) * 100).toFixed(2);
                    if (state.progress) {
                        state.progress();
                    }

                    this.uploadFileInBlocks(reader, state);
                }, err => {
                    this.messageService.showClientSideErrors('Oops something went wrong while uploading, please try again.')

                    this.loaderService.displayBar(false);
                });
        }
    };

    this.uploadFileInBlocks(reader, state);

    return {
        cancel: () => {
            state.cancelled = true;
        }
    };
}

我已经调试了这段代码，并发现下面的代码行

 this.http.put(uri, requestData, options).retryWhen(error => {
                return error
                    .flatMap((error: any) => {
                        if (error.status === 503) {
                            return Observable.of(error.status).delay(1000)
                        }
                        return Observable.throw({ error: 'No retry' });
                    })
                    .take(5)
                    .concat(Observable.throw({ error: 'Sorry, there was an error (after 5 retries)' }));
            })

我得到status = 0，并且在另一个浏览器中工作正常。有什么问题？ IE-11 Win-10版本

似乎您正在尝试自己构建HTTP请求。为什么不考虑使用Azure存储JavaScript SDK？

https://www.npmjs.com/package/@azure/storage-blob

dat %>%
  group_by(user_id, mobile_id) %>%
  arrange(created_at) %>%
  filter(difftime > -600)

将视频上传到Blob存储在Internet Explorer中不起作用
