1+# tx-signer
2+严格来说，tx-signer并不属于SDK，它是bytomd中构建交易、对交易签名两大模块的java实现版。因此，若想用tx-signer对交易进行离线签名，需要由你在本地保管好自己的私钥。
3+
4+如果你的目的是完全脱离于bytomd全节点，可能需要自己做更多额外的工作。比如，在构建交易时，需要花费若干个utxo（Unspent Transaction Output）作为交易的输入，如果没有全节点则需要自身来维护utxo。当使用tx-signer构建完成一笔交易并签名后，若没有全节点的帮助，也需要自己实现P2P网络协议将交易广播到其他节点。
5+
6+本文不会对以上技术细节进行讨论，而是利用bytomd全节点查询可用的utxo构建交易，对交易进行签名并序列化后，同样使用bytomd提交交易。
7+
8+## 准备工作
9+
10+#### 将Maven依赖引入到你的项目中
11+1. 获取SDK源码
12+
13+ ```
14+ git clone https://github.com/Bytom/bytom-java-sdk.git
15+ ```
16+
17+2. 打包成JAR包并安装到本地的Maven仓库
18+
19+ ```
20+ $ mvn clean install -DskipTests
21+ ```
22+
23+3. 在项目的POM文件中添加依赖。其中，第一个依赖是bytomd api的封装，可用于查询可用的utxo以及提交交易；第二个依赖用于构建交易以及对交易进行离线签名。
24+ ```xml
25+ <dependency>
26+ <groupId>io.bytom</groupId>
27+ <artifactId>java-sdk</artifactId>
28+ <version>1.0.0</version>
29+ </dependency>
30+
31+ <dependency>
32+ <groupId>io.bytom</groupId>
33+ <artifactId>tx-signer</artifactId>
34+ <version>1.0.0</version>
35+ </dependency>
36+ ```
37+
38+## 构建交易
39+
40+#### 普通交易
41+**1.** 查询可用的utxo
42+
43+在本文中，以下将全部使用全节点来查询可用的utxo，你也可以构建一套自己的utxo维护方案。
44+```java
45+Client client = Client.generateClient();
46+UnspentOutput.QueryBuilder builder = new UnspentOutput.QueryBuilder();
47+builder.accountAlias = "bytom";
48+List<UnspentOutput> outputs = builder.list(client);
49+```
50+利用SDK只需要四行代码就能查询可用的utxo（SDK具体文档详见[java-sdk documentation](java-sdk/README.md)）。在QueryBuilder中可以指定是否为未确认的utxo（默认false），也可以通过from和count来进行分页查询（默认查询所有）。
51+假设在当前账户下查询得到这样一个utxo：

72+**2.** 构建交易
73+
74+现在需要往`0014c832e1579b4f96dc12dcfff39e8fe69a62d3f516`这个control program转100个BTM。代码如下：
75+
76+```java
77+String btmAssetID = "ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff";
78+// 下面的字段与utxo中的字段一一对应
79+SpendInput input = new SpendInput();
80+input.setAssetId(btmAssetID);
81+input.setAmount(41250000000L);
82+input.setProgram("001437e1aec83a4e6587ca9609e4e5aa728db7007449");
83+input.setSourcePosition(0);
84+input.setSourceID("2d3a5d920833778cc7c65d7c96fe5f3c4a1a61aa086ee093f44a0522dd499a34");
85+input.setChange(false);
86+input.setControlProgramIndex(1);
87+// 选择使用BIP32还是BIP44来派生地址，默认BIP44
88+input.setBipProtocol(BIPProtocol.BIP44);
89+// 账户对应的密钥索引
90+input.setKeyIndex(1);
91+// 自身本地保管的私钥，用于对交易进行签名
92+input.setRootPrivateKey("4864bae85cf38bfbb347684abdbc01e311a24f99e2c7fe94f3c071d9c83d8a5a349722316972e382c339b79b7e1d83a565c6b3e7cf46847733a47044ae493257");
93+
94+Transaction tx = new Transaction.Builder()
95+ .addInput(input)
96+ // 加入需要转入的output
97+ .addOutput(new Output(btmAssetID, 10000000000L, "0014c832e1579b4f96dc12dcfff39e8fe69a62d3f516"))
98+ // 剩余的BTM用于找零
99+ .addOutput(new Output(btmAssetID, 31250000000L, "0014bb8a039726df1b649738e9973db14a4b4fd4becf"))
100+ .setTimeRange(0)
101+ .build();
102+
103+String rawTransaction = tx.rawTransaction();
104+
105+```
106+
107+对交易调用build方法后，自动会对交易进行本地的验证和签名操作。注意，在本地只是做简单的字段验证，本地验证通过并不代表交易合法。最后对交易调用rawTransaction方法返回交易序列化后的字符串。
108+
109+
110+**3. 提交交易**
111+
112+本文利用bytomd全节点来提交交易：
113+```java
114+HashMap<String, Object> body = new HashMap<>();
115+body.put("raw_transaction", "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");
116+Transaction.SubmitResponse response = client.request("submit-transaction", body, Transaction.SubmitResponse.class);
117+```
118+交易提交成功后，response返回交易ID。

121+#### 发行资产交易
122+**1. 查询可用的utxo**
