内容图文
我正在尝试在Chrome中进行跨域JSONP调用,但我不断回复“Uncaught SyntaxError：Unexpected token：”
我试过：更改响应内容类型,设置xhr标头,JSON.stringify,这里提供的大多数解决方案,但到目前为止没有任何工作:-(
$.ajax({
type: "POST",
url: "https://www.virustotal.com/vtapi/v2/url/report",
crossDomain: true,
contentType: "application/json; charset=UTF-8",
dataType: 'jsonp',
data: {
apikey: "*",
resource: "http://www.1001freefonts.com/font/BaroqueScript.zip"
},
jsonp: false,
jsonpCallback: receive,
success: function (data, textStatus, jqXHR) {
console.log("Data retrieved: " + data);
}
}).done(function () {
console.log('I think we are done here');
})
.error(function (e) {
console.log(arguments);
console.log('something went funny here');
})
.complete(function (xhr, status) {
console.log("complete");
if (status === 'error' || !xhr.responseText) {
console.log('error');
}
else {
console.log("data found:" + xhr.responseText);
//...
}
});
});
function receive(saveData) {
if (saveData == null) {
console.log("DATA IS UNDEFINED!"); // displays every time
}
console.log("Success is " + saveData); // 'Success is undefined'
}
在调试器中,我可以看到响应

我在http://jsonlint.com/上验证了它,它表明它是一个有效的JSON.
这是响应标题
cache-control:no-cache
content-encoding:gzip
content-length:695
content-type:application/json
date:Wed, 13 Feb 2013 12:00:33 GMT
server:Google Frontend
status:200 OK
vary:Accept-Encoding
version:HTTP/1.1
任何人有任何想法/建议？
解决方法:
在彻底测试之后,很明显当ajax期望JSONP作为回报时(由于跨域限制),不可能捕获JSON对象结果.即使响应状态= 200.
我一直在测试使用jQuery AJAX调用,试图看看结果是否仍然可以捕获 – 尽管浏览器抛出了解析错误 – 但它似乎不可能.看起来响应文本在JS工作完成后到达标题.
正如@Florian F. @Likwid_T @Christoph上面所建议的那样,一定要使用服务器端脚本才能使其正常工作.其他开发人员似乎热衷于使用C#编写的代理作为解决方案.
