Question

我正在使用javascript，我得到一个图像文件并将其编码为基础64，如此

function el(id){return document.getElementById(id);} // Get elem by ID



function readImage() {
    if ( this.files && this.files[0] ) {
        var FR= new FileReader();
        FR.onload = function(e) {
             el("img").src = e.target.result;
             el("base").innerHTML = e.target.result;
        };       
        FR.readAsDataURL( this.files[0] );
    }
}

el("asd").addEventListener("change", readImage, false);

编码文本是这样的，看起来像这样

data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/4gxYSUNDX1BST0ZJTE.........

现在我想用一个我知道怎么做的帖子发送这些数据，但是当我读到我在另一边发送的数据时，我只看到data:image/jpeg，Base64编码的起始位置和方式我可以把它作为字符串传递吗？

我像这样发帖子

var base64data;
//base64data is declared in the function readImage and I log it in this one and it has data
function callHttpReq () {

var http = new XMLHttpRequest();
var url = "/admin/website_sql/save_info.py";
var params = "website_photo=" + base64data;
http.open("POST", url, true);
console.log(base64data);
//Send the proper header information along with the request
http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.onreadystatechange = function() {//Call a function when the state changes.
    if(http.readyState == 4 && http.status == 200) {
        console.log(http.responseText);
    }
}
http.send(params);

由于

使用POST请求传递Base64
