升级后sugarcrm文件下载错误 [英] sugarcrm fileDownload error after upgrade

问题描述

我在升级 Sugar7.8 后收到此错误，它调用了我的文件下载.

I received this error after I upgraded sugar7.8, Which calling my filedownload.

{"error":"need_login","error_message":"No valid authentication for user."}

经过一些调查发现，糖升级了 OAuth 的 API 调用.以下是我的代码:

After some Investigation found tht sugar upgraded the API calls for OAuth. Following is my CODE:

 api.fileDownload(api.buildURL("Quotes/" + model.get("id") + "/pdf/download?OAuth-Token=" + api.getOAuthToken()), {
        success: function() {
            app.alert.show("pdf_download_api_success", {
                level: "success",
                messages: SUGAR.language.get('Quotes', 'LBL_QUOTE_PDF_GENERATED'),
                autoClose: true
            });
        },});

推荐答案

经过大量研究，我想出了解决此问题的方法.

After so much research, I came up with a solution for this issue.

注意:api.fileDownload(使用OAuth-token没有支持文档.

Note: There is no supporting document for api.fileDownload( to use OAuth-token.

所以我尝试使用 XMLHttpRequest 并且效果很好.

So i tried using XMLHttpRequest and it worked fine.

解决方案

    var request = new XMLHttpRequest();
    request.open('GET', api.buildURL("YOURMODULE/" + model.get("id") + "/pdf/download"), true);
    request.setRequestHeader('OAuth-Token', api.getOAuthToken()); // UR TOKEN
    request.responseType = "blob";
    request.onload = function (e) {
        if (this.status === 200) {
            // `blob` response
            // create `objectURL` of `this.response` : `.pdf` as `Blob`
            var file = window.URL.createObjectURL(this.response);
            var a = document.createElement("a");
            a.href = file;
            /*request.onreadystatechange = function() {
              if(this.readyState == this.HEADERS_RECEIVED) {
                console.log(request.getResponseHeader("Content-Type"));
              }
            }*/

            a.download =  request.getResponseHeader("FileName");
            document.body.appendChild(a);
            a.click();
            document.body.removeChild(a);
        };
    };
    request.send();
