导读:有没有办法将大型 JSON对象直接流式传输到HttpResponseMessage流? 这是我现有的代码: Dictionarystring,string hugeObject = new Dictionarystring,string(); // fill with 100,000 key/values. Each string is 32 chars. HttpResponseMessage response =
有没有办法将大型
JSON对象直接流式传输到HttpResponseMessage流?
这是我现有的代码: Dictionary<string,string> hugeObject = new Dictionary<string,string>(); // fill with 100,000 key/values. Each string is 32 chars. HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK); response.Content = new StringContent( content: JsonConvert.SerializeObject(hugeObject),encoding: Encoding.UTF8,mediaType: "application/json"); 哪个适用于较小的物体.但是,调用JsonConvert.SerializeObject()将对象转换为字符串的过程会导致大对象出现有问题的内存峰值. 我想做相当于what’s described here for deserialization. 解决方法
您可以尝试使用
PushStreamContent 并使用
JsonTextWriter 写入:
HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK); response.Content = new PushStreamContent((stream,content,context) => { using (StreamWriter sw = new StreamWriter(stream,Encoding.UTF8)) using (JsonTextWriter jtw = new JsonTextWriter(sw)) { JsonSerializer ser = new JsonSerializer(); ser.Serialize(jtw,hugeObject); } },"application/json"); (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
