API Invoke Methods

Open Platform API is invoking by HTTP Method，API is using REST Style，developers should assemble the HTTP Request according a certain format to invoke API,you can refer to example code for details.

一，Invoke Parameters

When invoking API ,you must input the systematic and applied parameters.

1）Systematic Parameters detailed instruction:

2）Applied Paramters,please refer to the API Params Instruction.

3）sign

When calling an API to server ,need SIGN Verify to the request params.Here is the example:

accorgin params name(apart sign and image),sort all the request params by alphabetic order:key + value....key+value

Example：sort foo=1,bar=2,baz=3 to bar=2,baz=3,foo=1, splice the params name and value then get the string bar2baz3foo1 splice secretKey to the start and end of params sting.

Example：secretKey value is secret123, you will get this string :secret123bar2baz3foo1secret123 , and then upper it after md5 encryption.

JAVA Instance Code:

     //signContent   is the string to be encrypted after the splice
     String sign= "";
     try {
          MessageDigest md = MessageDigest.getInstance("MD5");
          md.update(signContent.getBytes("UTF-8"));
          byte[] byteData = md.digest();
          StringBuilder sb = new StringBuilder();
          for(int b : byteData){
              b = b&0xFF;
              if(b<16)
                  sb.append('0');
             sb.append(Integer.toHexString(b));
          }
          sign= sb.toString().toUpperCase();
      } catch (Exception e) {
        e.printStackTrace();
      }
