AJAX請求返回200OK，但是盡管返回數據為JSON仍失敗

Question

編輯：就我而言，未返回正確信息的原因是我試圖使用JSONP連接到CORS數據設置，而服務器沒有為我的特定計算機訪問設置它。 我需要與某人交談並調整服務器的配置文件的權限。 那就是真正發生的事情，我無法弄清楚，因為我認為CORS和JSONP是同義詞，但是實際上它們的執行方式不同，並且需要設置某些服務器權限。

簡介：我有一個$ .ajax請求，該請求ping服務器以查找數據。 它失敗，但是數據顯示成功。

進入網絡，它將顯示響應。 我要它。 這是我無法掌握的。

錯誤：說失敗，但是返回是：

{"readyState":4,"status":200,"statusText":"success"}

因此，這意味着在客戶端某處已對其進行了標記。 響應為：

["Asset","AssetElementDefMap","AssetFile","AssetFileCategory","AssetFileCategoryObjectMap","AssetFilesFieldMap","AssetFilesReportMap","AssetTree","AssetType","BicUrl","CancelledUpload","CurrentValue","DataTypeInstanceMembers","DataTypeInstances","DataTypeMembers","DeviceDatabase","ElementDef","ElementDefEnvironment","ElementDefFormMap","ElementDefManual","ElementDefStructUnit","ElementDefStructUnitList","Field","FieldChoice","FieldFormScriptMap","FileType","FileTypeAssetFileCategoryMap","ForgotPassword","Form","FormScriptFunction","FormType","in_id","InspectionType","Inspector","MobileFormOSMap","MobileReportTypeFormMap","MobileReportTypeFormTypeMap","ProfileProperty","Report","ReportSubAssetMap","ReportType","ReportTypeAssetTypeMap","ReportTypeInspectionTypeMap","ReportValue","WorkingSet"]

編輯： AJAX請求：

var u = "myusername";
var p = "mypass";
var up = u + ":" + p;
$.ajax({
    type: "GET",
    url: "http://xx.xxx.xx.x/mas3/DataSources/inspecttech.inspecttech/Schema/Classes/",
    contentType: "application/json; charset=utf-8",
    dataType: "jsonp",
    headers: {Authorization: "Basic "+up},
    success: function (r) {
        alert("Success: " + JSON.stringify(r));
    },
    error: function (r) {
        alert("Failure: " + JSON.stringify(r));
    }
});

響應為：

 Content-Type:application/json ["Asset","AssetElementDefMap",…,"WorkingSet"] 

那不是JSONP腳本 ，而是純JSON（缺少“填充”，即回調函數）。 由於請求是跨域的，因此您無法訪問它-並且即使資源加載狀態為200 OK ，也無法將其作為腳本執行。
