如何将oauth_token和client_id发送到GraphQL客户端端点的请求体中

Question

你好，朋友们，我想在oauth_token客户端的请求体中传递GraphQL和client_id。所以我如何传递它们，因为GraphQLRequest只有三个字段(即查询、变量和OperationName)。请建议一下。

using GraphQL.Client;

var heroRequest = new GraphQLRequest{ Query = Query };
var graphQLClient = new GraphQLClient("URL");

var  graphQLResponse = await graphQLClient.PostAsync(heroRequest);

Answer 1

可以使用来自DefaultRequestHeaders的GraphQLClient.将授权(或任何其他参数)添加到标头中

var graphClient = new GraphQLClient("https://api.github.com/graphql");
graphClient.DefaultRequestHeaders.Add("Authorization", $"bearer {ApiKey}");

var request = new GraphQLRequest
{
    Query = @"query { viewer { login } }"
};

var test = await graphClient.PostAsync(request);

在这里，您可以从HttpClient：Setting Authorization Header of HttpClient找到更多关于该HttpClient：Setting Authorization Header of HttpClient的详细信息。

此外，在git上创建了一个相关的问题。

Answer 2

使用GraphQLHttpClient而不是GraphQLClient

示例：

public class DemoController : Controller
{
    private readonly GraphQLHttpClient _client;
    
    public DemoController(GraphQLHttpClient client)
    {
        _client = client;
    }

    public async Task<ActionResult> YourMethod()
    {
        _client.HttpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("JWT", yourToken);
        var query = new GraphQLRequest
        {
            Query = "query{......}"
        }
        ...
    }
}

当然，您必须在注册您的GraphQLHttpClient在Startup。

示例：

services.AddScoped(s => new GraphQLHttpClient(Configuration["YourGraphQLUri", new NewtonsoftJsonSerializer()));

Answer 3

var graphQLClient = new GraphQLHttpClient("localhost/graphql", new NewtonsoftJsonSerializer()); 
graphQLClient.HttpClient.DefaultRequestHeaders.Add("Authorization", "Bearer ????");
