Synchronous operations are disallowed. Call ReadAsync or set AllowSynchronousIO to true instead.

#事故现场

在asp.net core web api项目中，读取Request.body的stream流时，报如下错误：

Synchronous operations are disallowed. Call ReadAsync or set AllowSynchronousIO to true instead.

代码如下：

var request = context.HttpContext.Request;
if (request.Method == "POST")
{request.Body.Seek(0, SeekOrigin.Begin);using (var reader = new StreamReader(request.Body, Encoding.UTF8)){var data = reader.ReadToEnd();}
}

#解决方法

同步读取body的方式需要ConfigureServices中配置允许同步读取IO流，否则可能会抛出异常 Synchronous operations are disallowed. Call ReadAsync or set AllowSynchronousIO to true instead.
根据使用的托管的服务进行配置或直接使用异步读取方式。

public void ConfigureServices(IServiceCollection services)
{//其他services.Configure<KestrelServerOptions>(x => x.AllowSynchronousIO = true).Configure<IISServerOptions>(x=>x.AllowSynchronousIO = true);
}
