小编use*_*367的帖子

我正在尝试使用发布请求将文件发送到我的服务器,但是当它发送它时会导致错误:

$http.post($rootScope.URL, {params: arguments}, {headers: {
    "Access-Control-Allow-Origin" : "*",
    "Access-Control-Allow-Methods" : "GET,POST,PUT,DELETE,OPTIONS",
    "Access-Control-Allow-Headers": "Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With"
}

所以我用Google搜索了错误并添加了标题:

$http.post($rootScope.URL, {params: arguments}, {headers: {
    "Access-Control-Allow-Origin" : "*",
    "Access-Control-Allow-Methods" : "GET,POST,PUT,DELETE,OPTIONS",
    "Access-Control-Allow-Headers": "Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With"
}

然后我得到错误:

$http.post($rootScope.URL, {params: arguments}, {headers: {
    "Access-Control-Allow-Origin" : "*",
    "Access-Control-Allow-Methods" : "GET,POST,PUT,DELETE,OPTIONS",
    "Access-Control-Allow-Headers": "Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With"
}

所以我用谷歌搜索了那个,我能找到的唯一类似的问题提供了一个半答案然后关闭作为主题.我应该添加/删除哪些标题？

所以我试图在我的网站上获取文件上传的进度条.如果我只是上传资源

$.ajax({
    url: $rootScope.URL,  //Server script to process data
    type: 'POST',
    beforeSend: beforeSendHandler,
    success: completeHandler,
    error: errorHandler,
    data: formData,
    cache: false,
    contentType: false,
    processData: false
});

它工作得很好,但是如果我添加事件来听取进度:

$.ajax({
    url: $rootScope.URL,  //Server script to process data
    type: 'POST',
    xhr: function() {  // Custom XMLHttpRequest
        var myXhr = $.ajaxSettings.xhr();
        if(myXhr.upload){ // Check if upload property exists
            myXhr.upload.addEventListener('progress',progressHandlingFunction, false); // For handling the progress of the upload
        }
        return myXhr;
    },
    beforeSend: beforeSendHandler,
    success: completeHandler,
    error: errorHandler,
    data: formData,
    cache: false,
    contentType: false, …
