jquery – Ajax POST和Django Tastypie

前端之家收集整理的这篇文章主要介绍了jquery – Ajax POST和Django Tastypie前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
curl --dump-header - -H "Content-Type: application/json" -X POST --data '{"latlong": "test"}' http://localhost:8000/geo/api/geolocation/

以上工作正常,但当我尝试在下面的ajax中复制POST时,我得到500错误.

$.ajax({
  type: 'POST',url: 'http://localhost:8000/geo/api/geolocation/',data: '{"latlong": "test"}',success: latlongSaved(),dataType: "application/json",processData:  false,});

错误信息是:

{"error_message": "The format indicated 'application/x-www-form-urlencoded' had no available deserialization method. Please check your ``formats`` and ``content_types`` on your Serializer." .... }

值得注意的是这是跨域的,我使用的是通过git:gist找到的django-crossdomainxhr-middleware.py

如果我向ajax调用添加内容类型,如下所示:

contentType: "application/json"

我收到此错误

XMLHttpRequest cannot load http://localhost:8000/geo/api/geolocation/. Request header field Content-Type is not allowed by Access-Control-Allow-Headers.

解决方法

您在通话中明确声明了您的内容类型,但您并未具体说明您的 jQuery.ajax()通话.

更新您的JavaScript以准确定义内容类型:

$.ajax({
  type: 'POST',contentType: "application/json"
});
