问题描述
我在 .netcore 中使用 HTTPClient，但在添加自定义接受标头时遇到问题.
I'm using HTTPClient in .netcore but I'm facing an issue when I add a custom accept header.
var client = new HttpClient { Timeout = new TimeSpan(0, 5, 0)};
client.DefaultRequestHeaders.Clear();
client.DefaultRequestHeaders.TryAddWithoutValidation("Accept", "application/vnd.pagseguro.com.br.v3+json;charset=ISO-8859-1");
但在此之后，我看到的是自动添加了一个空格，导致application/vnd.pagseguro.com.br.v3+json; charset=ISO-8859-1".该空间给我带来了麻烦，因为服务器向我返回了一个错误.没有那个空间它就可以工作.
But after this, what I see is that a space has been automaticaly added, resulting in "application/vnd.pagseguro.com.br.v3+json; charset=ISO-8859-1". That space is causing me a trouble because the server return me an error. Without that space it works.
有什么方法可以删除 HttpClient 标头中的那个空格?常规方法不起作用，例如 trim，或者只是 replace 一旦它位于 DefaultRequestHeaders 中，我无法直接修改.
There is any way to remove that space in HttpClient header? Conventional ways do not work, like trim, or just a replace once it's inside a DefaultRequestHeaders and I can't modify directly.
推荐答案
我能够通过使用 .net Framework 4.5 创建一个新的微服务来解决这个问题.使用 HttpWebRequest，标头不会在字符集和接受之间自动添加空格.
I was able to turnarround this issue by making a new microservice with .net Framework 4.5. Using HttpWebRequest, the header dont add an automaticaly space between the charset and accept.
