javascript - 在 Blockcypher 上广播原始交易，POST 请求出现错误

Question

我有一个原始比特币交易，我想使用 Blockcypher API 进行广播，我正在使用 axios 发送 POST 请求:

var axios = require('axios')

axios.post('https://api.blockcypher.com/v1/bcy/test/txs/send', {
    "tx": "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"
  })
  .then(function (response) {
    console.log(response);
  })
  .catch(function (response) {
    console.log(response);
  });

在终端中运行此命令时出现错误:

{ data: { error: 'Couldn\'t deserialize request: json: cannot unmarshal string into Go value of type pooch.JSONTx' }

知道我的帖子有什么问题吗？我尝试用 tx 而不是“tx”发帖，但它仍然不起作用。在文档中，他们建议这样做:

var pushtx = {
  tx: "01000000011935b41d12936df99d322ac8972b74ecff7b79408bbccaf1b2eb8015228beac8000000006b483045022100921fc36b911094280f07d8504a80fbab9b823a25f102e2bc69b14bcd369dfc7902200d07067d47f040e724b556e5bc3061af132d5a47bd96e901429d53c41e0f8cca012102152e2bb5b273561ece7bbe8b1df51a4c44f5ab0bc940c105045e2cc77e618044ffffffff0240420f00000000001976a9145fb1af31edd2aa5a2bbaa24f6043d6ec31f7e63288ac20da3c00000000001976a914efec6de6c253e657a9d5506a78ee48d89762fb3188ac00000000"
};

$.post('https://api.blockcypher.com/v1/bcy/test/txs/push', JSON.stringify(pushtx))
  .then(function(d) {console.log(d)});

但是当我这样做时，我收到错误:

TypeError: undefined is not a function

所以我认为使用 axios 更容易，因为我至少得到了 Blockcypher 的回复。任何帮助将不胜感激!

完整披露:BlockCypher 的开发者倡导者请点击此处。首先，每Greg's评论中的建议，在第一种情况下，使用 /txs/send 端点，我们期望 TX Skeleton 。 Creating Transactions section 中对此进行了更清晰的概述。文档。

使用 /txs/push 应该适用于您的情况，尽管我也遇到了错误。为了进行调查，我首先检查了我们的 /txs/decode 端点，这是调试的良好第一步，因为它将向您展示我们的服务器如何反序列化原始事务。您可以read more about it here .

var decodetx = {
  tx: "01000000011935b41d12936df99d322ac8972b74ecff7b79408bbccaf1b2eb8015228beac8000000006b483045022100921fc36b911094280f07d8504a80fbab9b823a25f102e2bc69b14bcd369dfc7902200d07067d47f040e724b556e5bc3061af132d5a47bd96e901429d53c41e0f8cca012102152e2bb5b273561ece7bbe8b1df51a4c44f5ab0bc940c105045e2cc77e618044ffffffff0240420f00000000001976a9145fb1af31edd2aa5a2bbaa24f6043d6ec31f7e63288ac20da3c00000000001976a914efec6de6c253e657a9d5506a78ee48d89762fb3188ac00000000"
};

$.post('https://api.blockcypher.com/v1/bcy/test/txs/decode', JSON.stringify(decode))
  .then(function(d) {console.log(d)});

这对我有用，返回解码的(但未推送!)交易:

这里一切看起来都很好。所以我尝试使用/txs/push，这次通过cURL收集返回中的错误消息:

curl -d '{"tx":"01000000011935b41d12936df99d322ac8972b74ecff7b79408bbccaf1b2eb8015228beac8000000006b483045022100921fc36b911094

{"error": "Error validating transaction: Transaction with hash 4e6dfb1415b4fba5bd257c129847c70fbd4e45e41828079c4a282680528f3a50 already exists.."}

果然，根据该错误消息，该交易已存在于我们的内部测试网上，如下所示:

https://live.blockcypher.com/bcy/tx/4e6dfb1415b4fba5bd257c129847c70fbd4e45e41828079c4a282680528f3a50/

我认为您正在尝试推送已推送的原始交易。如果您想测试交易创建，我建议您在我们的测试网上生成您自己的地址:

http://dev.blockcypher.com/#generate-address-endpoint

您可以使用我们的水龙头将一些硬币发送到这些地址:

http://dev.blockcypher.com/#testing(或通过此处的网络界面:https://accounts.blockcypher.com/blockcypher-faucet)。

然后按照“创建交易”中概述的步骤操作:

希望有帮助!
