尝试
json从
files[0]属性创建对象，将其转换
file为
base64字符串
js
$("#image").on("change", function(e) { var name = $("#af_rpta_propertyland_filename").val() , file = e.target.files[0] , filename = name.length > 1 ? name + ".pdf" : file.name , filetype = file.type , filesize = file.size , data = { "filename":filename, "filetype":filetype, "filesize":filesize } , reader = new FileReader(); reader.onload = function(e) { data.file_base64 = e.target.result.split(/,/)[1]; $.post("fileupload.php", {file:data}, "json") .then(function(data) { // parse `json` string `data` var filedata = JSON.parse(data) // do stuff with `data` (`file`) object , results = $("<a />", { "href": "data:" + filedata.filetype + ";base64," + filedata.file_base64, "download": filedata.filename, "target": "_blank", "text": filedata.filename }); $("body").append("<br>download:", results[0]); }, function(jqxhr, textStatus, errorThrown) { console.log(textStatus, errorThrown) }) }; reader.readAsDataURL(file)});的PHP
<?php if (isset($_POST["file"])) { // do php stuff // call `json_enpre` on `file` object $file = json_enpre($_POST["file"]); // return `file` as `json` string echo $file;};jsfiddle
