微信接口獲取用戶信息

必須的參數：appid和appSecret

 

①獲取code

 

接口連接示例：

https://open.weixin.qq.com/connect/oauth2/authorize?appid=wxbafc7fdf3664b600&redirect_uri=http%3a%2f%2f0708.pinzhi365.com%2findex_tb.html&response_type=code&scope=snsapi_userinfo&state=STATE&connect_redirect=1#wechat_redirect

參數說明：

appid                服務號自帶的值，爲固定值

redirect_uri       回調的連接，在通過接口獲取到了code以後，頁面會跳轉到此參數對應的連接上，且域名必定要對應服務號所配置的域              名

                          且該連接必需要通過urlencode

response_type  固定值

scope                固定值：snsapi_userinfo或snsapi_base(不彈出受權頁面，只能獲取用戶openid)

state                  重定向後會帶上state參數，開發者能夠填寫a-zA-Z0-9的參數值，最多128字節

 

調用結果：

若是用戶贊成受權，頁面將跳轉至

http://0708.pinzhi365.com/index_tb.html?code=011bdbf34b5748203155ef831321b9af&state=STATE

------------------------------------------------------------------------------------------------------------

②經過code換取網頁access_token

 

接口連接示例：

https://api.weixin.qq.com/sns/oauth2/access_token?

 

appid=wxbafc7fdf3664b600&secret=81f9832f79e858b247aa6a2d09d66341&code=011bdbf34b5748203155ef831321b9af&grant_type=authorization_code

 

參數說明：

appid                 同①

secret                 服務號自帶，即appSecret，爲固定值

code                  從①獲取的值

grant_type         固定值

 

調用結果：

示例：

{

    "access_token": "OezXcEiiBSKSxW0eoylIeByO7M0QcUqqAnU8rzQAkrRdZmwxk9aQoDf5WT5aSvx6wBenI2Jmz_jBs-025_piaJ81bvZrb9Q1oEPOPZq7RMQRZT2sBN3-mk6siHEeXIN9WD1ybSIfoHaITDowh1AN8Q",

    "expires_in": 7200,

    "refresh_token": "OezXcEiiBSKSxW0eoylIeByO7M0QcUqqAnU8rzQAkrRdZmwxk9aQoDf5WT5aSvx695Vnx345AXlPPDt50Fbl0zfUI5eTGht57oMtwLx_aMyjYF3Juj4AVA_VX0hltk10WL47Z3_v6BnKCD_o9v2S5Q",

    "openid": "oAhzJs2lQRR6Dd1U95S1lrlMKjSE",

    "scope": "snsapi_userinfo",

    "unionid": "o_LdHt0WTwyrk41R2vcAs2v5XFQk"

}

------------------------------------------------------------------------------------------------------------

③經過access_token和openid獲取用戶信息

 

接口連接示例：

 

https://api.weixin.qq.com/sns/userinfo?access_token=OezXcEiiBSKSxW0eoylIeByO7M0QcUqqAnU8rzQAkrRdZmwxk9aQoDf5WT5aSvx6wBenI2Jmz_jBs-025_piaJ81bvZrb9Q1oEPOPZq7RMQRZT2sBN3-mk6siHEeXIN9WD1ybSIfoHaITDowh1AN8Q&openid=oAhzJs2lQRR6Dd1U95S1lrlMKjSE&lang=zh_CN

 

參數說明：

access_token      由②所獲取

openid                由②所獲取

lang                    語言類型，爲固定值

調用結果：

示例：

{
    "openid": "oAhzJs2lQRR6Dd1U95S1lrlMKjSE",
    "nickname": "雨天發呆",
    "sex": 1,
    "language": "zh_CN",
    "city": "",
    "province": "",
    "country": "中國",
    "headimgurl": 

"http://wx.qlogo.cn/mmopen/TTQibyKjrickytMz9ZYicsibWECY84XyItRFZMp5kYv7vVyNxGMCkl1x1L6eOzGIT2ZGhApDx3n0jDfMy3aodO8PXQ/0",

    "privilege": [],
    "unionid": "o_LdHt0WTwyrk41R2vcAs2v5XFQk"
}

JAVA發送http get請求的方法：

 

所必須的jar包：commons-httpclient-3.0.1.jar

 

 

import java.io.ByteArrayOutputStream;

import java.io.IOException;

 

import org.apache.commons.httpclient.DefaultHttpMethodRetryHandler;

import org.apache.commons.httpclient.HttpClient;

import org.apache.commons.httpclient.HttpException;

import org.apache.commons.httpclient.HttpStatus;

import org.apache.commons.httpclient.methods.GetMethod;

import org.apache.commons.httpclient.params.HttpMethodParams;

public static String sendGet(String url) {

  String newStr = "";

  // 構造HttpClient的實例

  HttpClient httpClient = new HttpClient();

  // 設置 Http 鏈接超時爲3秒

  httpClient.getHttpConnectionManager().getParams().setConnectionTimeout(3000);

  // 建立GET方法實例

  GetMethod getMethod = new GetMethod(url);

  // 設置 get 請求超時爲 3秒

  getMethod.getParams().setParameter(HttpMethodParams.SO_TIMEOUT, 3000);

  // 使用系統提供的默認的恢復策略

  getMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,

    new DefaultHttpMethodRetryHandler());

  try {

   // 執行getMethod

   int statusCode = httpClient.executeMethod(getMethod);

   if (statusCode != HttpStatus.SC_OK) {

    System.err.println("Method failed: " + getMethod.getStatusLine());

   }

   // 讀取內容

   newStr = new String(getMethod.getResponseBodyAsString().getBytes("ISO8859-1"),"UTF-8").trim();

  } catch (HttpException e) {

   e.printStackTrace();

  } catch (IOException e) {

   e.printStackTrace();

  } finally {

   // 釋放鏈接

   getMethod.releaseConnection();

  }

  ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

 

  System.out.println(newStr);

  return newStr;

  }

 

利用json-lib-2.3-jdk15.jar來解析json的方法：

String openIdJson = "

{

    "access_token": "OezXcEiiBSKSxW0eoylIeByO7M0QcUqqAnU8rzQAkrRdZmwxk9aQoDf5WT5aSvx6wBenI2Jmz_jBs-025_piaJ81bvZrb9Q1oEPOPZq7RMQRZT2sBN3-mk6siHEeXIN9WD1ybSIfoHaITDowh1AN8Q",

    "expires_in": 7200,

    "refresh_token": "OezXcEiiBSKSxW0eoylIeByO7M0QcUqqAnU8rzQAkrRdZmwxk9aQoDf5WT5aSvx695Vnx345AXlPPDt50Fbl0zfUI5eTGht57oMtwLx_aMyjYF3Juj4AVA_VX0hltk10WL47Z3_v6BnKCD_o9v2S5Q",

    "openid": "oAhzJs2lQRR6Dd1U95S1lrlMKjSE",

    "scope": "snsapi_userinfo",

    "unionid": "o_LdHt0WTwyrk41R2vcAs2v5XFQk"

}

";

 

JSONObject jo = JSONObject.fromObject(openIdJson);

String openId = jsonObjectOpenId.getString("openid");
