调用HTTPClient.PostAsync时设置Authorization/Content-Type标头 [英] Set Authorization/Content-Type headers when call HTTPClient.PostAsync

问题描述

使用简单的HTTPClient时，在哪里可以将标头设置为REST服务调用?

Where can I set headers to REST service call when using simple HTTPClient?

我愿意:

HttpClient client = new HttpClient();
var values = new Dictionary<string, string>
{
    {"id", "111"},
    {"amount", "22"}
};
var content = new FormUrlEncodedContent(values);
var uri = new Uri(@"https://some.ns.restlet.uri");

var response = await client.PostAsync(uri, content);
var responseString = await response.Content.ReadAsStringAsync();

UPD

我要添加的标题:

{
    "Authorization": "NLAuth nlauth_account=5731597_SB1, nlauth_email=[e-mail], nlauth_signature=Pswd1234567, nlauth_role=3",
    "Content-Type": "application/json"
}

我应该执行以下操作吗?

Should I do the following?

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", "NLAuth nlauth_account=5731597_SB1, nlauth_email=[e-mail], nlauth_signature=Pswd1234567, nlauth_role=3","Content-Type":"application/json");

推荐答案

添加标头的方法如下:

HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", "Your Oauth token");

或者，如果您需要一些自定义标头:

Or if you want some custom header:

HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Add("HEADERNAME", "HEADERVALUE");

此答案已经有SO响应，请参见下文:

This answer has SO responses already, see below:

• 在使用httpClient.GetAsync时添加标头
• 设置HttpClient的授权标头

• Adding headers when using httpClient.GetAsync
• Setting Authorization Header of HttpClient

更新

似乎您要添加两个标题.授权和内容类型.

Seems you are adding two headerrs; authorization and content type.

string authValue = "NLAuth nlauth_account=5731597_SB1,nlauth_email=[e-mail], nlauth_signature=Pswd1234567, nlauth_role=3";
string contentTypeValue = "application/json";

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue(authValue);
client.DefaultRequestHeaders.Add("Content-Type", contentTypeValue);
