获取微信OpenId 先获取code 再通过code获取authtoken，从authtoken中取出openid给前台微信端一定不要忘记设定网页账号中的授权回调页面域名流程图如下主要代码页面js代码 /* 写cookie */ function setCookie(name, value) { var Days = 30; var exp = new Date(); exp/connect/oauth2/authorize?appid=") /sns/oauth2/access_token?"; StringBuffer url = new StringBuffer(uri); url.URL; public class HttpClientUtil { // 设置body体 public static void setBodyParameter(String sb, HttpURLConnection conn) throws IOException { DataOutputStream out = new DataOutputStream(conn.getOutputStream()); out.writeBytes(sb); out.flush(); out.close(); } // 添加签名header public static HttpURLConnection CreatePostHttpConnection(String uri) throws MalformedURLException, IOException, ProtocolException { URL url = new URL(uri); HttpURLConnection conn = (HttpURLConnection) url.openConnection(); conn.setUseCaches(false); conn.setDoInput(true); conn.setDoOutput(true); conn.setRequestMethod("POST"); conn.setInstanceFollowRedirects(true); conn.setConnectTimeout(30000); conn.setReadTimeout(30000); conn.setRequestProperty("Content-Type","application/json"); conn.setRequestProperty("Accept-Charset", "utf-8"); conn.setRequestProperty("contentType", "utf-8"); return conn; } public static byte[] readInputStream(InputStream inStream) throws Exception { ByteArrayOutputStream outStream = new ByteArrayOutputStream(); byte[] buffer = new byte[1024]; int len = 0; while ((len = inStream.read(buffer)) != -1) { outStream.write(buffer, 0, len); } byte[] data = outStream.toByteArray(); outStream.close(); inStream.close(); return data; } } 封装AuthToken的VO类 package com.huatek.shebao.wxpay; public class AuthToken { private String access_token; private Long expires_in; private String refresh_token; private String openid; private String scope; private String unionid; private Long errcode; private String errmsg; public String getAccess_token() { return access_token; } public void setAccess_token(String access_token) { this.access_token = access_token; } public Long getExpires_in() { return expires_in; } public void setExpires_in(Long expires_in) { this.expires_in = expires_in; } public String getRefresh_token() { return refresh_token; } public void setRefresh_token(String refresh_token) { this.refresh_token = refresh_token; } public String getOpenid() { return openid; } public void setOpenid(String openid) { this.openid = openid; } public String getScope() { return scope; } public void setScope(String scope) { this.scope = scope; } public String getUnionid() { return unionid; } public void setUnionid(String unionid) { this.unionid = unionid; } public Long getErrcode() { return errcode; } public void setErrcode(Long errcode) { this.errcode = errcode; } public String getErrmsg() { return errmsg; } public void setErrmsg(String errmsg) { this.errmsg = errmsg; } } 感谢阅读，希望能帮助到大家，谢谢大家对本站的支持！
