I connect a nginx http service by socket,i use java Language：

url：api.weibo.com/2/users/show.json

GET /2/users/show.json HTTP/1.1
Host: api.weibo.com
Connection: keep-alive
Cache-Control: max-age=0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.99 Safari/537.36
Accept-Language: zh-CN,zh;q=0.8,en;q=0.6
Cookie: PHPSESSID=uc67dtcb5r3orchgv0dgdd0f57; think_template=default

but it return：

HTTP/1.1 400 Bad Request
Server: Weibo
Date: Sat, 24 Jan 2015 10:07:33 GMT
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked
Connection: keep-alive
Api-Server-IP: 10.75.0.174
Vary: Accept-Encoding

60
{"error":"source paramter(appkey) is missing","error_code":10006,"request":"/2/users/show.json"}
0

i don't know what is the '60' and '0'

if i use HTTP/1.0 instand of HTTP/1.1,it return:

HTTP/1.1 400 Bad Request
Server: Weibo
Date: Sat, 24 Jan 2015 10:22:09 GMT
Content-Type: application/json;charset=UTF-8
Connection: close
Api-Server-IP: 10.75.5.92
Vary: Accept-Encoding

{"error":"source paramter(appkey) is missing","error_code":10006,"request":"/2/users/show.json"}

if i use socket connect iis or apache,all ok to use HTTP/1.1

Anybody can tell me why,and how to Solve?

The webservice returns the content in chunks, by first sending the length of the next chunk. It is using Chunked Transfer Encoding.

You are saying you can speak HTTP/1.1 with GET /2/users/show.json HTTP/1.1 and

All HTTP/1.1 applications MUST be able to receive and decode the "chunked" transfer-coding....

You could use something like the Apache HttpClient or some other Java HTTP client library to avoid implementing HTTP on your own.

  • thanks for your answer.i just study the http protocol,use socket can let me learn more. if the socket return 0,it mean i can close socket?and if use the "chunked",where i can see?or just do it myself? – cs x Jan 24 '15 at 11:06
  • If you read 0 from the socket/stream after a chunk while using chunked transfer encoding you could close the socket. If you meant the return value of the read call on the socket that returns 0 it does just mean that there is no data to read from the socket. It would return -1 if the connection got closed. – flob Jan 24 '15 at 15:38
