Question

我正在尝试批量上传多个pdf。每个文件都以特定格式命名

02-2015 HIP BS32

日期/管道缩写/位置缩写。

我通过循环运行文件，将缩写与数据库中的列表进行比较。然后，我将这些属性分配给对象，然后再将其传递给API控制器。管道和位置表的设置完全相同。我遇到的问题是管道问题。这就是问题所在，

$scope.pip = $scope.pipeLookup[matches[1]];
$scope.loc = $scope.locationLookup[matches[2]];

locationLookup与Location Abbreviation匹配并将其放在$ scope.loc变量中。但是pipeLookup不起作用。它当然是抛出错误，因为管道属性是未定义的。我不确定我是不是只是在寻找一些东西。如果需要更多信息，请告诉我

 $scope.companies = Company.query(function () { });
$scope.locations = Location.query(function () { });
$scope.pipes = Pipe.query(function () { });
$scope.selectCompany = function () {
    var id = $scope.companyId.CompanyId
    $http.get('/api/apiCompany/' + id)
        .success(function (result) {
            $scope.CompanyName = result.CompanyName
        });
};//

$scope.pipeLookup = {};
$scope.locationLookup = {};

$scope.upload = function () {
    var files = $scope.files;
    if (files && files.length) {
        for (var i = 0; i < files.length; i++) {
            var file = files[i];

            $scope.pipes.map(function (pip) {
                $scope.pipeLookup[pip['PipeAb']] = pip;
            });
            $scope.locations.map(function (loc) {
                $scope.locationLookup[loc['LocationAb']] = loc;
            });

            var matches = file.name.match(/^\d+\D\d+\s*?(\S*)\s*(\S*?)\./i);

            $scope.pip = $scope.pipeLookup[matches[1]];
            $scope.loc = $scope.locationLookup[matches[2]];

            $upload.upload({
                url: '/api/apiBatchPipeLine',
                fields: {
                    'typeId': 1,
                    'companyId': $scope.companyId.CompanyId,
                    'documentDate': $scope.model.documentDate,
                    'pipeId': $scope.pip['PipeId'],
                    'pipeName': $scope.pip['PipeName'],
                    'locationId': $scope.loc['LocationId'],
                    'locationAb': $scope.loc['LocationAb']
                },
                file: file
            }).progress(function (evt) {
                var progressPercentage = parseInt(100.0 * evt.loaded / evt.total);
                console.log('progress: ' + progressPercentage + '% ' + evt.config.file.name);
            }).success(function (data, status, headers, config) {
                console.log('file ' + config.file.name + 'uploaded. Response: ' +
                            JSON.stringify(data));
            }).error(function (err, result) {
                console.log(err, result);
            });

        }
    }

你的正则表达式期望结尾有一个点（。）字符，但你的字符串末尾不包含一个点（。），因此它失败了。

如果我尝试使用正则表达式^\d+\D\d+\s*?(\S*)\s*(\S*?)\. here并传入02-2015 HIP BS32，那么它就不匹配，因为你的正则表达式最终期望.字面值。< / p>

更新：这是pipeLookup JSON的片段

"HIP ": {
"$id": "9",
"PipeId": 9,
"PipeAb": "HIP ",
"PipeName": "American Midstream High Point Pipeline",
"Documents": null

}

这里的关键是＆＃34; HIP＆＃34;注意HIP之后的额外空格。这就是$scope.pipeLookup[matches[1]]什么都不返回的原因。在将其存储在pipeLookup对象

中之前删除该尾随空格

更新：仔细看看，如果file.name包含此值02-2015 HIP BS32，并且您希望获得HIP值，则可以使用以下正则表达式

/^\d+\D\d+\s*(\S*\s*)(\S*)/i

以下是此正则表达式示例的jsbin live demo
