Question

我正在使用angularjs尝试将多个文件上传到我的sharepoint API，所以我使用foreach语句和$ q.all等待所有内容完成上传，但不知怎的，我的代码已经被认为已经解决了第一次上传文件。

factory.UploadFilesByBatch = function（arrayBuffer，folderName）{ var promises = [];

    angular.forEach(arrayBuffer, function(item) {
        // factory.GetFormDigest().then(function(data) {
        var deferred = $q.defer();
        // promises.push(deferred);

        console.log("UploadFilesByBatch Try - " + item.fileName + "Uploading")
        $http({
            url: webUrl + "web/getfolderbyserverrelativeurl('" + folderLocation + "')/files/add(overwrite=true, url='" + item.fileName + "')",
            method: "POST",
            headers: {
                "Accept": "application/json;odata=verbose",
                "X-RequestDigest": xrequestDigest,
                "content-Type": "application/json;odata=verbose"
            },
            data: item.fileBuffer,
            transformRequest: []
        }).then(function(result) {
            console.log("UploadFilesByBatch Success - " + item.fileName + "Uploaded")
            item.sharepointFileLocation = result.data.d.ServerRelativeUrl;
            deferred.resolve(item);

        }, function(result, status) {
            console.log("UploadFilesByBatch Error - " + item.fileName + "Failed")
            console.log(JSON.stringify(result))
            deferred.reject(result);
        });
        promises.push(deferred);

        // })

    })
    return $q.all(promises);

};

You're not quite using the $q.all correctly. You want to push the actual promise into your array of promises. You'll also want to get rid of all of the deferred stuff, the $http call already is a promise so you can push that directly into your promise array.

Instead of (?<=[a-z]\\.\\s) You want to do

promises.push(deferred);

This will leave you with an array of promises. You can then use promises.push($http({ url: webUrl + "web/getfolderbyserverrelativeurl('" + folderLocation + "')/files/add(overwrite=true, url='" + item.fileName + "')", method: "POST", headers: { "Accept": "application/json;odata=verbose", "X-RequestDigest": data.d.GetContextWebInformation.FormDigestValue, "content-Type": "application/json;odata=verbose" }, data: item.fileBuffer, transformRequest: [] }) ); to iterate over the results like so:

$q.all(promises)

AngularJS Foreach不等待
