Embed a Blob using PDFObject

问题

I'm using: https://pdfobject.com/

To display an embedded pdf file on my web app. However I cannot render a pdf created from a blob.

This is what I've tried:

var arrayBufferView = new Uint8Array(response.Body.data);
var file = new Blob([arrayBufferView], {
    type: response.ContentType
});
var url = window.URL.createObjectURL(file)
PDFObject.embed(url, "#my-container");

Gets me this result on html:

<div id="my-container" class="ng-scope pdfobject-container">

    <embed class="pdfobject" src="blob:http%3A//localhost%3A4000/869a8d9a-7eaa-48dd-99aa-49bf299114aa" type="application/pdf" style="overflow: auto; width: 100%; height: 100%;" internalinstanceid="88">

</div>

However the embed container displays nothing in my browser. I'm using Chrome 51.0.2704.103 m

回答1:

Try using <iframe> element, requesting resource as a Blob

html

<div id="my-container" class="ng-scope pdfobject-container">
    <iframe src="" type="application/pdf" width="100%" height="100%" style="overflow: auto;">
    </iframe>
</div>

javascript

var xhr = new XMLHttpRequest();
// load `document` from `cache`
xhr.open("GET", "/path/to/file.pdf", true); 
xhr.responseType = "blob";
xhr.onload = function (e) {
    if (this.status === 200) {
        // `blob` response
        console.log(this.response);
        var file = window.URL.createObjectURL(this.response);
        document.querySelector("iframe").src = file;

    }
};
xhr.send();

This is what l believe you were looking for.

function previewPdf(billName) {

var xhr = new XMLHttpRequest();
xhr.open('GET', 'home/download?pdfBillId=' + billName, true);
xhr.responseType = 'arraybuffer';
xhr.onload = function(e) {
    if (this.status == 200) {
        var file = new Blob([this.response], { type: 'application/pdf' });
        var fileURL = URL.createObjectURL(file);
        var viewer = $('#viewpdf');
        PDFObject.embed(fileURL, viewer);
    }
};
xhr.send(); 
}
