how to use Post to download zip shapefile itself? about ogre HOT 5 CLOSED

Hi Wavded,

I try another way to create Post request like below, but it can not find the path of zip file,

var parameters ={
json:GeoJson,
outputName:"zippedshp.zip"
}
var options ={
url:"http://ogre.adc4gis.com/convertJson",
type: "POST",
data: parameters,
contentype:"application/zip",
success:function(data){
if(data){
console.log(data.path);
if(data.path) {
//Create an hidden iframe, with the 'src' attribute set to the created ZIP file.
var dlif = $('<iframe/>',{'src':data.path}).hide();
//Append the iFrame to the context
this.append(dlif);
}
else if (data.error){
alert (data.error);
}
else{
alert ("Somthing wrong");
}
}
}

}
$.ajax(options);

hi Waveded,

I find one solution can download the zipped shapefile through Post request , as shown below. however, the download zip file can not be used due to : Windows cannot open the folder. The compressed (zipped) Folder 'C:\Users\niuzh\Downloads\zippedshp(6).zip' is invalid.

Thanks for your comments.

var params ={
    json:GeoJson, 
    outputName:"zippedshp.zip"
}

$.ajax({
    url:'http://ogre.adc4gis.com/convertJson',
    type: "POST",
    data: params,
    success: function(response, status, xhr) {
        var filename = "zippedshp";
        var type = xhr.getResponseHeader('Content-Type');
        var blob = new Blob([response], { type: type });

        if (typeof window.navigator.msSaveBlob !== 'undefined') {
            window.navigator.msSaveBlob(blob, filename);
        }
        else {
            var URL = window.URL || window.webkitURL;
            var downloadUrl = URL.createObjectURL(blob);
            //console.log(downloadUrl);
            if (filename){
                var a = document.createElement("a");
                if (typeof a.download === 'undefined') {
                    window.location = downloadUrl;
                }
                else {
                    a.href = downloadUrl;
                    a.download = filename;
                    document.body.appendChild(a);
                    a.click();
                }
            }
            else {
                window.location = downloadUrl;
            }
            setTimeout(function () { URL.revokeObjectURL(downloadUrl); }, 100);
        }
    }
});

I am not up to speed on latest browser file handling but my current understanding is that you cannot trigger a download from an AJAX request. I believe you want to create a hidden form and submit that to get the download behavior.

Thank you so much. it is working well.

is it possible to host the similar service locally?

yes, the readme has instructions, there also is a Dockerfile included in the project if you want to build it that way.
