如何經過getTransaction來確認交易成功

當經過sendTransaction發出交易以後，transaction並無當即上鍊，因此要先經過txpool.status.pending來看看若是大於0，說明你的結點中有pending的transaction。（或者經過eth.getBlock("pending")來查看你的交易是否在pending塊中）

固然若是沒有上鍊，這個交易是在你的結點中發出的，能夠直接經過getTransaction來獲取交易，返回的結果中blockHash爲零，blockNumber爲null：

{ blockHash: '0x0000000000000000000000000000000000000000000000000000000000000000',
  blockNumber: null,
  from: '0xdfb1b9b8693366eb9044ffd8c00058abc904558b',
  gas: 90000,
  gasPrice: ...,
  hash: '0x0b4f742149fc3018a168950b56786846da99675913dbc043971cbe25ac7792ac',
  input: '0x48656c6c6f20576f726c64',
  nonce: 2,
  to: null,
  transactionIndex: null,
  value: ...

可是他奶奶的，若是有一種狀況，交易成功了，可是out of gas，以前的邏輯都是成功了，也上鍊了，可是交易卻沒有成功，我在轉erc20幣的時候遇到很多這種狀況，這怎搞？

經過debug_traceTransaction來看看這筆交易有沒有error。

首先你的結點rpc必須是開放debug的：

geth --rpc --rpcapi "eth,net,web3,debug" console

而後調用debug_traceTransaction：

curl localhost:8545 -X POST --header 'Content-type: application/json' --data '{"jsonrpc":"2.0", "method":"debug_traceTransaction", "params":["0x3684f071b34da1116282ee88a106a8f2a266d273ef7d8964957f65128fb58d77", {}], "id":1}'

結果相似這樣：

{
  gas: 85301,
  returnValue: "",
  structLogs: [{
      depth: 1,
      error: "",
      gas: 162106,
      gasCost: 3,
      memory: null,
      op: "PUSH1",
      pc: 0,
      stack: [],
      storage: {}
  },
    /* snip */
  {
      depth: 1,
      error: "",
      gas: 100000,
      gasCost: 0,
      memory: ["0000000000000000000000000000000000000000000000000000000000000006", "0000000000000000000000000000000000000000000000000000000000000000", "0000000000000000000000000000000000000000000000000000000000000060"],
      op: "STOP",
      pc: 120,
      stack: ["00000000000000000000000000000000000000000000000000000000d67cbec9"],
      storage: {
        0000000000000000000000000000000000000000000000000000000000000004: "8241fa522772837f0d05511f20caa6da1d5a3209000000000000000400000001",
        0000000000000000000000000000000000000000000000000000000000000006: "0000000000000000000000000000000000000000000000000000000000000001",
        f652222313e28459528d920b65115c16c04f3efc82aaedc97be59f3f377c0d3f: "00000000000000000000000002e816afc1b5c0f39852131959d946eb3b07b5ad"
      }
  }]

從structLogs中一個個看是否有error非null的存在，若是有說明實際是失敗了
