Question

我有一个上传的rtf文件，一旦上传，我希望它被解析并转换为json文件。我使用的主要是角度。我上传工作正常，我只是解决问题。该文件确实被清理，但它没有正确格式化为json文件。任何人都有任何关于最好的事情的建议吗？

this.parseFile=function(file, uploadUrl){

    reader.onload = function(onLoadEvent){

        $rootScope.$apply(function(){
            var dataURL = reader.result;
            setUpData(dataURL);
        });

    };
    reader.readAsText(file);
};
function saveFile(file){

    var fd = new FormData();
    fd.append('save_file', file);
    $http({
        method: 'POST',
        url: "includes/loadFile.php",
        data: fd,
        transformRequest: angular.identity,
        headers: {'Content-Type': undefined}

    })
    .success(function (data, status, headers, config) {
        msg = {
                title: "success",
                cls: "success",
                msg: data
        };
        popUp(msg);
    })
    .error(function (data, status, header, config) {
        msg = {
                title: "error",
                cls: "danger",
                msg: data
        };
        popUp(msg);
    });
};
function setUpData(data)

    text = data;

    text = text.replace('/[\p{Z}\s]{2,}/u', ' ');
    // skip over the heading stuff
    j= text.indexOf('{',1); // skip ahead to the first part of the header

    var loc = 1;
    var t ="";

我对此的期望是创建一个干净的格式良好的JSON文件，然后它可以在它们所在的页面上显示回用户。基本上使用新上传的解析数据刷新页面。

有一个JS RTF解析器可能有所帮助。然后，您需要对结果进行json编码。 https://github.com/lazygyu/RTF-parser

不确定这是否能解答您的问题，但更多信息可能有助于锁定修复程序。
