如何更改FLURL客户端的HTTP请求内容类型？ [英] How to change the HTTP Request Content Type for FLURL Client?

问题描述

我正在使用flurl提交HTTP请求，这非常有用。现在我需要将某些请求的 Content-Type标题更改为application / json; odata = verbose

I am using flurl to submit HTTP request and this is very useful. Now I need to change the "Content-Type" header for some of the requests to "application/json;odata=verbose"

    public async Task<Job> AddJob()
    {

        var flurlClient = GetBaseUrlForGetOperations("Jobs").WithHeader("Content-Type", "application/json;odata=verbose");
        return await flurlClient.PostJsonAsync(new
        {
            //Some parameters here which are not the problem since tested with Postman

        }).ReceiveJson<Job>();
    }

    private IFlurlClient GetBaseUrlForOperations(string resource)
    {
        var url = _azureApiUrl
            .AppendPathSegment("api")
            .AppendPathSegment(resource)
            .WithOAuthBearerToken(AzureAuthentication.AccessToken)
            .WithHeader("x-ms-version", "2.11")
            .WithHeader("Accept", "application/json");
        return url;
    }

您可以看到我是如何尝试添加上面的标题（ .WithHeader（Content-Type，application / json; odata = verbose））

You can see how I tried to add the header above (.WithHeader("Content-Type", "application/json;odata=verbose"))

不幸的是这给了我以下错误：

Unfortunately this gives me following error:

InvalidOperationException：Misused header name。确保请求
标头与HttpRequestMessage一起使用，响应标头与
一起使用HttpResponseMessage和带有HttpContent对象的内容标题。

"InvalidOperationException: Misused header name. Make sure request headers are used with HttpRequestMessage, response headers with HttpResponseMessage, and content headers with HttpContent objects."

我还尝试了flurl的ConfigureHttpClient方法，但无法找到如何/在何处设置内容类型标题。

I also tried flurl's "ConfigureHttpClient" method but could not find how/where to set the content type header.

推荐答案

我发现的评论和另一篇文章（将在我再次找到时添加参考）指出了我正确的方向。
我的问题的解决方案如下：

The comments and another post I found (will add reference when I find it again) have pointed me to the right direction. The solution for my problem looks like:

        var jobInJson = JsonConvert.SerializeObject(job);
        var json = new StringContent(jobInJson, Encoding.UTF8);
        json.Headers.ContentType = MediaTypeHeaderValue.Parse("application/json; odata=verbose");

        var flurClient = GetBaseUrlForOperations("Jobs");

        return await flurClient.PostAsync(json).ReceiveJson<Job>();
