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？我尝试使用 tx 而不是“tx”发布，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，我得到了错误：

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。任何帮助将非常感激！

全面披露：BlockCypher 的开发者倡导者在这里。首先，Per Greg在评论中的建议，在第一种情况下，使用我们期望TX Skeleton/txs/send的端点。这在文档的创建事务部分中有更清楚的概述。

/txs/push尽管我也遇到了错误，但使用应该适用于您的情况。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。你可以在这里阅读更多关于它的信息。

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，返回已解码（但未推送！）事务：

这里的一切看起来都很好。所以我尝试使用/txs/push，这一次，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，该交易已经存在于我们的内部测试网上，如下所示：

https://live.blockcypher.com/bcy/tx/4e6dfb1415b4fba5bd257c1298​​47c70fbd4e45e41828079c4a282680528f3a50/

我认为您试图推动已经推动的原始交易。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向这些地址发送一些硬币：

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

然后按照“创建事务”中概述的步骤进行操作：

希望有帮助！
