uploader上传问题，总是413，太大！压缩后还是这样

压缩成50PX 还是不行，是代码问题吗？

function uploader(path) {

var n = docompress(path);  
if (n == 0) {  
    var wt = plus.nativeUI.showWaiting();  
    var server = API_URL + 'User/uploadFace';  

    var task = plus.uploader.createUpload(server, {  
        method: 'POST'  
    }, function(t, status) {  
        if (status == 200) {  
            hu.alert('上传成功!');  
            wt.close();  
        } else if (status == 413) {  
            hu.alert('头像文件太大!');  
            wt.close();  
        } else {  
            hu.alert('上传失败!');  
            wt.close();  
        }  
    });  
    task.addData('uid', hu.getItem('uid'));  
    task.addData('username', hu.getItem('username'));  
    task.addData('token', hu.getItem('token'));  
    task.addFile(path, {  
        key: 'love'  
    });  
    task.start();  
}  
else hu.alert('图片压缩失败!');  

}
//图片压缩
function docompress(path) {
//压缩图片
plus.zip.compressImage({
src: path,
dst: path,
quality: 10,
width: "50px",
height: "50px",
overwrite: true
}, function() {},
function(error) {
return 1;
})
return 0;
}
