Question

我正在尝试向服务器发送帖子请求，但我似乎不断收到此错误：

XMLHttpRequest cannot load https://nim-rd.nuance.mobi:9443/nina-webapi/TTS/. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

这是我的javascript函数：

function play(){
    var request = new XMLHttpRequest();

    request.open("POST", http_url, true);
    request.setRequestHeader("Content-type", "application/json");
    request.setRequestHeader("nmaid", nmaid);
    request.setRequestHeader("nmaidkey", nmaidKey);
    request.responseType = "arraybuffer";

    request.send(JSON.stringify({
        text: "Hi my name is Ted",
        tts_type: "text"
    }));

    request.onreadystatechange = function(event) {
        console.log("Entered");
        if (request.readyState === 4 && request.status === 200) {
            console.log("Entered2");
        }
    }
}

以下是响应标题：

OPTIONS /nina-webapi/TTS/ HTTP/1.1
Host: nim-rd.nuance.mobi:9443
Connection: keep-alive
Access-Control-Request-Method: POST
Origin: null
User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36
Access-Control-Request-Headers: content-type, nmaid, nmaidkey
Accept: */*
Accept-Encoding: gzip, deflate, sdch, br
Accept-Language: en-US,en;q=0.8

这是请求标题：

HTTP/1.1 200 OK
Allow: POST, TRACE, OPTIONS
Content-Length: 0
Server: Jetty(9.3.11.v20160721)

我在网上进行了一些研究，看起来帖子不被视为预检请求，为什么我一直收到这个错误？我也尝试将以下内容添加到我的代码中，但没有运气......

    request.setRequestHeader("Access-Control-Allow-Origin", "*");
    request.setRequestHeader("Access-Control-Allow-Headers", "*");
    request.setRequestHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS");

对于post命令，请求的资源错误上没有“Access-Control-Allow-Origin”标头
