编辑： 在我的情况下，它没有返回正确信息的原因是我试图使用 JSONP 连接到 CORS 数据设置，而服务器没有为我的特定计算机访问设置它。我需要与某人交谈并调整服务器配置文件的权限。这就是真正发生的事情，我无法弄清楚，因为我认为 CORS 和 JSONP 是同义词，但实际上它们的执行方式不同，并且需要设置某些服务器权限。

简介：我有一个 $.ajax 请求，它对服务器查找数据进行 ping 操作。它失败了，但数据显示成功。

进入网络，它显示响应。我要它。它就在我的掌握之外。

错误：说它失败，但返回是：

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

所以，这意味着在客户端的某个地方，它被标记了。回应是：

["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"]

回应是：

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

那不是JSONP 脚本，而是纯 JSON（缺少“填充”，即回调函数）。由于请求是跨域的，因此您不能访问它 - 即使资源加载200 OK状态时，将其作为脚本执行也会失败。
