元数据查询失败：Breeze JS

Question

我正在使用ASP.net Web Api开发Breeze JS To Dos应用程序。当我向资源请求时，我得到“元数据查询失败：odata / Todos / Metadata; NaN”。但是，当我手动请求/ odata / Todos / Metadata时，它工作正常。你对此有什么想法吗？

Answer 1

尝试：

var dataService = new breeze.DataService({
    serviceName: "http://localhost:2099/api/yourcontent/",
    hasServerMetadata: false,
});

var manager = new breeze.EntityManager({ dataService: dataService });

Answer 2

我发现datajs中的MaxDataServiceVersion标头导致404s ...

尝试

var oldClient = OData.defaultHttpClient;
var myClient = {
    request: function (request, success, error) {
        delete request.headers.MaxDataServiceVersion;
        return oldClient.request(request, success, error);
    }
};
OData.defaultHttpClient = myClient;
