1. 通过HTTP协议用：
|
|||
|
|
直接拼接URL参考：https://public.internetapi.cn/docs/bdcontract/doc/ContractAPI.html#id69
|
|||
|
|
|
|||
|
|
使用SDK参考test目录下的SmartContractHttpClientTest.java
|
|||
|
|
```java
|
|||
|
|
//当需要发起签名调用时，使用正确的privateKey和publicKey。
|
|||
|
|
SmartContractHttpClient client =
|
|||
|
|
new SmartContractHttpClient(
|
|||
|
|
SM2KeyPair.fromJson(
|
|||
|
|
"{\"privateKey\":\"...\",\"publicKey\":\"...\"}"),
|
|||
|
|
IP,
|
|||
|
|
port);
|
|||
|
|
System.out.println(client.executeContractAsString(contractID_or_contractName, operation,arg));
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
2.通过WebSocket调用
|
|||
|
|
使用SDK参考test目录下的SmartClientTest.java
|
|||
|
|
```java
|
|||
|
|
SmartContractClient client = new SmartContractClient("ws://ip:port/SCIDE/SCExecutor") ;
|
|||
|
|
//如果需要指定key，也可传入key参数。
|
|||
|
|
//SM2KeyPair key = SM2KeyPair.fromJson("json格式的密钥对");
|
|||
|
|
//client = new SmartContractClient("...",key);
|
|||
|
|
client.waitForConnect();
|
|||
|
|
client.login();
|
|||
|
|
ContractRequest cr = new ContractRequest();
|
|||
|
|
cr.setContractID("xxx");
|
|||
|
|
cr.setAction("xxx");
|
|||
|
|
cr.setArg("xxx");
|
|||
|
|
JsonObject result = testClient.executeContractSync(cr);
|
|||
|
|
```
