JSON格式的Jquery.ajax API请求导致Chrome中出现“Uncaught SyntaxError：Unexpected token：”
我试图用jquery.ajax查询http://developer.pintlabs.com/brewerydb/api-documentation 。
这是我试过的两个Jquery请求（注意“O3tmVI”是一个虚拟ID）：
$.ajax({ url:"http://api.playground.brewerydb.com/beer/" + "O3tmVI" + "?key=A1029384756B&format=json", dataType: "jsonp", jsonpCallback: "callbackfunctie", success:function(oData){ var returnData = oData; console.log(returnData); } }); 和：
$.getJSON("http://api.playground.brewerydb.com/beer/" + "O3tmVI" + "?key=A1029384756B&format=json&jsoncallback=?", function(data){ console.log(data); });
两者都会导致此错误：
未捕获的SyntaxError：意外的令牌：
现在，返回的json对象如下所示：

我已经成功地将其validation为有效的JSON
现在，问题是我需要一个JSONP对象才能请求它（跨域）。 所以它必须包装在容器函数中。 这应该可以使用请求中的参数，但到目前为止，我已经尝试了几乎所有但没有成功…
我发现这篇文章有一个关于这个bug的简短条目： http ： //www.jquery4u.com/json/ajaxjquery-getjson-simple/
未捕获的SyntaxError：意外的令牌:(在crome中）无效Lable（在firefox中）“无效标签”错误可以通过将JSON数据传递给js回调来修复
但我真的不明白他在那里说什么
我究竟做错了什么？
我的猜测是http://api.playground.brewerydb.com/beer/上的服务正在返回json但不是 jsonp。 在jsonp标签中搜索“Unexpected token”，你会发现很多解释，例如这个。 json必须包装在一个javascript函数中，即回调，但是由跨域Web服务来支持jsonp。 这是由浏览器强制执行的，jQuery无法克服它。
API不支持JSONP设计
不，我们不[支持JSONP]，因为您必须公开您的API密钥。 最好的办法是设置一个中间代理。
看到twitter 。
请注意， Open Beer数据库的人员 确实支持JSONP。
