获取access token
新浪微博开放平台access token请求地址为：http://api.t.sina.com.cn/oauth/access_token
以下是请求参数列表:
oauth_consumer_key - GDdmIQH6jhtmLUypg82g
oauth_nonce - 9zWH6qe0qG7Lc1telCn7FhUbLyVdjEaL3MO5uHxn8
oauth_signature_method - HMAC-SHA1
oauth_token - 8ldIZyxQeVrFZXFOZH5tAwj6vzJYuLQpl0WUEYtWc
oauth_timestamp - 1272323047
oauth_verifier - pDNg57prOHapMbhv25RNf75lVRd6JDsni1AJJIDYoTY
oauth_version - 1.0
oauth_token_secret - x6qpRnlEmW9JbQn4PQVVeVG8ZLPEx6A0TOebgwcuA
第一步,准备base string(使用上文提到的方法)

%26oauth_verifier%3DpDNg57prOHapMbhv25RNf75lVRd6JDsni1AJJIDYoTY
%26oauth_version%3D1.0
接着将consumer_secret和oauth_token_secret连接起来，中间用&分割(这是准备密钥的方法,下面还会用到)：
MCD8BKwGdgPHvAuvgvz4EQpqDAtx89grbuNMRd7Eh98&x6qpRnlEmW9JbQn4PQVVeVG8ZLPEx6A0TOebgwcuA
生成的OAuth签名如下：
PUw/dHA4fnlJYM6RhXk5IU/0fCc=
然后向给定的url发送请求,请求头部一定要包含request token，request头部如下：
OAuth oauth_nonce="9zWH6qe0qG7Lc1telCn7FhUbLyVdjEaL3MO5uHxn8", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1272323047", oauth_consumer_key="GDdmIQH6jhtmLUypg82g", oauth_token="8ldIZyxQeVrFZXFOZH5tAwj6vzJYuLQpl0WUEYtWc", oauth_verifier="pDNg57prOHapMbhv25RNf75lVRd6JDsni1AJJIDYoTY", oauth_signature="PUw%2FdHA4fnlJYM6RhXk5IU%2F0fCc%3D", oauth_version="1.0"
新浪微博开放平台会返回应用需要的信息，包括用户名，oauth_token/oaut_token_secret(当然这里就是access token了)。 response内容如下：
oauth_token=819797-Jxq8aYUDRmykzVKrgoLhXSq67TEa5ruc4GJC2rWimw&oauth_token_secret=J6zix3FfA9LofH0awS24M3HcBYXO5nI1iYe8EfBA&user_id=819797&screen_name=openapi
现在就可以使用access token来发布信息了。
