I'm trying to read a JSON-encoded byte from a server, which will be indented, but of an unpredictable length, and no obvious termination byte. I would like to read the entire server response into a byte. The server will close the connection. Is it possible to do this using net
?
读取直到服务器关闭连接

As a supplement to @minikomi 's answer, I would like to add that, if you are sure that the bytes returned from the server are JSON encoded, there's a nice package
encoding/json
for this.http://golang.org/pkg/encoding/json/
If you are using a decoder to decode directly from a connection, sometimes the error won't be returned. You might want to use
fmt.Printf("%v ", whateverDecodedFromTheConnection)
to see what the decoder gets for your struct when the connection is closed.For example, in my case, where the
encoding/gob
decoder is used to decode a message from a tcp connection into a struct defined as:type MessageType struct { Type uint8 }
When the connection is closed,
decoder.Decode(&buffer)
returns{0}
. This might not be a common situation, but something needed to be watched out.本回答被题主选为最佳回答 , 对您是否有帮助呢?解决 无用评论 打赏 举报
