对于webRTC优惠,我收到错误“位置26的JSON中的意外令牌”。我正在使用ajax调用从数据库获取提供并将其作为纯文本返回以解析为JSON对象。当我尝试解析字符串时,我收到一个“JSON中的意外令牌”错误。
这是JSON作为普通字符串

和代码
$.ajax({
url: "./php/actions.php",
type: "post",
dataType: "text",
data: {type:'retrieve', roomid:roomid},
success: function(data){
//data is plain text from string of offer retrieved from db
$('.termp').text(data); //used to check raw text data for now
var offerSDP = JSON.parse(data); //returning error when trying to convert to json
remoteConn.setRemoteDescription(new RTCSessionDescription(offerSDP)); //needs an object
}
});
我之前在另一个应用程序中使用复制和粘贴方法取得了成功,我在其中获取原始文本数据并将其粘贴到文本区域,然后将JSON.parse(text-area.val())成功设置为sessionDescription,但这些方法看似相同但产生了不同的结果。
