在 Blockcypher 上广播原始交易，在 POST 请求时出现错误
Broadcasting Raw Transaction on Blockcypher, getting a error on POST request
我有一个原始比特币交易，我想用 Blockcypher API 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);
});
我在终端中 运行 时收到错误消息：
{ data: { error: 'Couldn\'t deserialize request: json: cannot unmarshal string into Go value of type pooch.JSONTx' }
知道我的 POST 出了什么问题吗？我尝试 post 与 tx 而不是 "tx" 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，因为我至少从 Blockcypher 那里得到了回复。任何帮助将不胜感激！
全面披露：BlockCypher 的开发倡导者在这里。首先，根据文档的 Greg's advice in the comments, in the first case, using the /txs/send endpoint we expect a TX Skeleton. This is outlined more clearly in the Creating Transactions section。
使用 /txs/push 应该适用于你的情况，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，这是调试的良好开端，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 read more about it here.

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：
我认为您正在尝试推送一个已推送的原始交易。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：

您可以使用我们的水龙头将一些硬币发送到这些地址：

（或通过此处的 Web 界面：https://accounts.blockcypher.com/blockcypher-faucet）。
然后按照 "Creating Transactions" 中列出的步骤进行操作：
