如何为backbone.js设置内容类型和POST？

Question

我可以设置content-type并POST在Backbone.js的？

this.save(data, {
    success: function (user) {
        callback(user.get('LoginStatus'))
    },

    error: function (user, result, xhr) {

    }
});

当我尝试进行REST服务调用时,我收到了错误请求,它在fiddler中工作.我们需要设置类型和内容类型吗？

这是我得到的错误

为骨干fetch和save方法包裹jQuery.ajax()功能,您可以通过在路过设置骨干Content-Type和请求方法jQuery.ajax() settings的对象直接到无论是fetch或save功能

例如使用fetch函数:

myModel.fetch({
    type: "POST",
    contentType: "application/json"
});

它使用的save功能相同:

myModel.save({
    type: "POST",
    contentType: "application/json"
});

另外我注意到你在save函数中提供了一个数据属性.如果要将JSON作为POSTed数据传递给URL,则需要在save函数中使用以下语法:

myModel.save({
    data: JSON.stringify(myObject),
    type: "POST",
    contentType: "application/json"
});
