新浪支付接口对接的总结

最近公司用户了新浪支付，账户托管，写的过程中发现有问题的话百度很少就记录下自己疑惑的地方

1.接口介入方式

这种接口介入的方式，各大平台都差不多的，支付宝啊，微信支付啊，融宝支付啊，银盈通啊。都是系统必要的参数，和接口需要的参数，拼一起然互加密。

新浪支付生成 sign 的方式，签名的方式可以是 RSA 的加密方式和 MD5 的加密的方式，不过新浪推荐的是MD5的加密方式，但是给的demo里面是RSA的方式，所有自己用的
也会是RSA的加密方式。

简单的例子   创建激活会员

public static SinaPayResponse createActivateMember(Map<String, Object> data) throws Exception {

SinaPayResponse response = new SinaPayResponse();

if (data == null || data.size() == 0) {
response.setCode(ResponceCodeEnum.MissingParameter.getCode());
response.setErrorMsg("传入的参数为空");
return response;

}

// 用户标识信息
if (data.get("identity_id") == null || data.get("identity_id").equals("")) {
response.setCode(ResponceCodeEnum.MissingParameter.getCode());
response.setErrorMsg("传入的参数:用户标识信息(identity_id)为空");
return response;
}

Map<String, Object> map = new HashMap<String, Object>();

map.put("identity_id", data.get("identity_id"));

// 用户标识类型,目前只支持UID
map.put("identity_type", SinaPayConfig.IDENTITY_TYPE);

// 1: 个人会员;2: 企业会员。默认是1
if (data.get("member_type") != null && !data.get("member_type").equals("")) {
map.put("member_type", data.get("member_type"));
}

// 系统参数
map.put("service", SinaPayConfig.CREATE_ACTIVATE_MEMBER);

String str = SinaUtils.createLinkString(map, true);

String res = "";

try {
res = CallServiceUtil.sendPost(SinaPayConfig.MEMBER_TSET_URL, str);
} catch (Exception e) {
response.setCode(ResponceCodeEnum.connectionTimedOut.getCode());
response.setErrorMsg("请求超时");
return response;
}

String result = URLDecoder.decode(res, SinaUtils.CHARSET);

Map<String, String> resultMap = GsonUtil.fronJson2Map(result);

if (SinaPayConfig.APPLY_SUCCESS.equals(resultMap.get("response_code"))) { // 成功
response.setCode(ResponceCodeEnum.success.getCode());
response.setErrorMsg("请求成功");
response.setResponseMap(resultMap);
return response;
} else {
response.setCode(ResponceCodeEnum.requestFails.getCode());
response.setErrorMsg(resultMap.get("response_message"));
response.setResponseMap(resultMap);
return response;
}
}

String str = SinaUtils.createLinkString(map, true); 这一步是在吧我们需要的参数，包括 系统的参数，也包括接口需要的参数，生成 待签名的 字符串

/**
* 把参数重新排序下
*
* @param map
* @param b
* @return
* @throws Exception
*/
public static String createLinkString(Map<String, Object> map, boolean encode) throws Exception {

map.put("version", SinaPayConfig.VERSION);
map.put("request_time", SinaTimeUtils.getTime());
map.put("partner_id", SinaPayConfig.PARTNER_ID);
map.put("_input_charset", SinaUtils.CHARSET);
String content = SinaUtils.getContent(map);
map.put("sign", SinaUtils.getSign(content));
map.put("sign_type", SinaPayConfig.SIGN_TYPE);

List<String> keys = new ArrayList<String>(map.keySet());
Collections.sort(keys);
String prestr = "";
String charset = (String) map.get("_input_charset");
for (int i = 0; i < keys.size(); i++) {
String key = keys.get(i);
String value = (String) map.get(key);
if (encode) {
try {
value = URLEncoder.encode(URLEncoder.encode(value, charset), charset);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
}
if (i == keys.size() - 1) {
prestr = prestr + key + "=" + value;
} else {
prestr = prestr + key + "=" + value + "&";
}
}

return prestr;
}

res = CallServiceUtil.sendPost(SinaPayConfig.MEMBER_TSET_URL, str); 这一步是在请求接口，返回结果

public static String sendPost(String url, String param) {
PrintWriter out = null;
BufferedReader in = null;
String result = "";
try {
URL realUrl = new URL(url);
URLConnection conn = realUrl.openConnection();
conn.setRequestProperty("accept", "*/*");
conn.setRequestProperty("connection", "Keep-Alive");
conn.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
conn.setDoOutput(true);
conn.setDoInput(true);
out = new PrintWriter(conn.getOutputStream());
out.print(param);
out.flush();
in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
result += line;
}
} catch (Exception e) {
System.out.println("POST请求异常:" + e);
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
if (in != null) {
in.close();
}
} catch (IOException ex) {
ex.printStackTrace();
}
}
return result;
}

这个时候返回的结果是经过URLencode的代码，所以需要 处理下

String result = URLDecoder.decode(res, SinaUtils.CHARSET);

Map<String, String> resultMap = GsonUtil.fronJson2Map(result); 这一步是在把得到的结果的传，转成Map

public static <T> T fronJson2Map(String json) {
return gson.fromJson(json, new TypeToken<Map<String, String>>() {
}.getType());
}

大部分的接口都是这样的调用的方式，有些接口需要的一些参数涉及用户的隐私，所以需要对参数进行RSA加密

/**
* 比如一些参数需要加密的话
*
* @param string 待加密的信息
* @throws Exception
* @throws
*/
public static String getRSAEncodeDoc(String data) throws Exception {
byte[] data_byte = RSA.encryptByPublicKey(data.getBytes(CHARSET), SinaPayConfig.ENCRYPT);
return Base64.encode(data_byte);
}

大概就是这么多了，可能还有些要注意的地方

1.在 请求审核企业会员资质（audit_member_infos）中需要上传 一个zip的压缩包，里面需要的内容都是定好了的，比如上传了8个文件，每个文件都以名称和后缀的形式放在一起，然后压缩成zip包，zip包的命名和 这个接口需要的传的参数 fileName 要一样，然后，用工具类，对zip包进行 MD5 摘要计算，计算的代码

public static String getFileMD5(File file) {
if (!file.isFile()){
return null;
}
MessageDigest digest = null;
FileInputStream in=null;
byte buffer[] = new byte[1024];
int len;
try {
digest = MessageDigest.getInstance("MD5");
in = new FileInputStream(file);
while ((len = in.read(buffer, 0, 1024)) != -1) {
digest.update(buffer, 0, len);
}
in.close();
} catch (Exception e) {
e.printStackTrace();
return null;
}

然后调用它给的一个上传文件的工具类，上传的代码

String file_path = data.get("file_path").toString();
File file = new File(file_path);
String filemd5 = Tools.getFileMD5(file);

System.out.println(filemd5);
System.out.println("-------------------------start------------------------------");
System.out.println("链接sftp");
sftp s = new sftp();
try {
s.upload("/upload/", file_path, s.connectSFTP());
System.out.print("sftp文件上传成功！");
s.ls("/upload/", s.connectSFTP());
} catch (SftpException e) {
e.printStackTrace();
System.out.print("sftp文件上传失败！");
response.setCode(ResponceCodeEnum.fileUploadFail.getCode());
response.setErrorMsg("sftp文件上传失败！");
return response;
}
System.out.println("sftp关闭");
System.out.println("-------------------------end------------------------------");

其他的都是接口调用了，都没啥了。
