Question

我通过ajax将八位字节流发送到我的PHP服务器。我希望将它作为八位字节流接收并解码，而不是字符串。问题是请求体是一个字符串，似乎ajax将它作为纯文本发送，即使我已经覆盖了mime类型。这是我的ajax：

    var xmlhttp;
    if (window.XMLHttpRequest) {
        xmlhttp = new XMLHttpRequest();
    } else {
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == XMLHttpRequest.DONE ) {
            if(xmlhttp.status == 200){
                console.log(xmlhttp);
            }
            else if(xmlhttp.status == 400) {
                alert('There was an error 400')
            }
            else {
                alert('something else other than 200 was returned')
            }
        }
    };
    xmlhttp.open("POST", "something.php", true);
    xmlhttp.overrideMimeType("application/octet-stream");
    xmlhttp.send(stream); // some array buffer

请求标头：

所以mime类型是octet-stream，但请求有效负载是一个字符串。怎么了？
