带有自定义标头的JayData oData请求 [英] JayData oData request with custom headers

问题描述

我需要将自定义标头发送到我的wcf oData服务，但是使用以下功能，标头不会被修改。

I need to send custom headers to my wcf oData Service but with the following function the headers dont get modified.

entities.onReady(function () {

    entities.prepareRequest = function(r) {
        r[0].headers['APIKey'] = 'ABC';
    };

    entities.DataServiceClient.toArray(function (cli) {
        cli.forEach(function (c) {
            console.log(c.Name)
        });
    });
});

标题不受影响。任何线索？

headers are not affected. any clue?

谢谢！

推荐答案

编辑

第二个想法，似乎JayData中的MERGE请求仍然存在问题。

EDIT

On second thought, it seems like there is still something broken in JayData for MERGE requests.

这不是CORS并且有与它无关！

This is NOT CORS and has nothing to do with it!

波纹管hack有效，但上述问题应该将此问题解决一个新的水平。

the bellow "hack" works, but the above question should take this problem to a new level.

没关系我找到了解决方案。

Nevermind I found a solution.

似乎 prepareRequest 是在JayData 1.3.2（ODataProvider）中断开。

It seems like prepareRequest is broken in JayData 1.3.2 (ODataProvider).

作为一个hack，我在providerConfiguration（oDataProvider.js）中添加了一个extraHeaders对象：

As a hack, I added an extraHeaders object in the providerConfiguration (oDataProvider.js):

  this.providerConfiguration = $data.typeSystem.extend({
                   //Leave content unchanged and add the following:
                    extraHeaders: {}
                }, cfg);

然后在第865行修改requestData这样：

then at line 865 modify requestData like this:

var requestData = [
                    {
                        requestUri: this.providerConfiguration.oDataServiceHost + sql.queryText,
                        method: sql.method,
                        data: sql.postData,
                        headers: _.extend({
                            MaxDataServiceVersion: this.providerConfiguration.maxDataServiceVersion
                        },this.providerConfiguration.extraHeaders)
                    },

注意：Iam使用lodash进行召集，任何js扩展应该可以解决问题。

NOTE: Iam using lodash for conveniance, any js extend should do the trick.

然后你就像这样创建你的客户：

then you just create your client like this:

 var entities = new Entities.MyEntities({
            name: 'oData',
            oDataServiceHost: 'http://myhost.com/DataService.svc',
            maxDataServiceVersion: "2.0",
            //enableJSONP: true,
            extraHeaders: {apikey:'f05d1c1e-b1b9-5a2d-2f44-da811bd50bd5', Accept:'application/json;odata=verbose'}
        }
    );
