我有一个原始的比特币交易,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);
});
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POST有什么问题吗?我尝试用tx而不是“ tx”发布信息,但仍然无法正常工作。在文档上,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
因此,我认为使用axios更容易,因为我至少得到了Blockcypher的回应。任何帮助将非常感激!
最佳答案
完整披露:此处是BlockCypher的开发人员倡导者。首先,在第一种情况下,使用/txs/send
端点在注释中使用Greg's建议,我们希望使用TX Skeleton。在文档的Creating Transactions section中对此进行了更清晰的概述。
使用/txs/push
应该适合您的情况,尽管我也遇到了错误。为了进行调查,我首先检查了/txs/decode
端点,这是调试的一个很好的第一步,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,返回已解码(但未推送!)的事务:

这里的一切看起来都很好。因此,这次我尝试使用
/txs/push
,通过cURL收集返回的错误消息:curl -d '{"tx":"01000000011935b41d12936df99d322ac8972b74ecff7b79408bbccaf1b2eb8015228beac8000000006b483045022100921fc36b911094

{"error": "Error validating transaction: Transaction with hash 4e6dfb1415b4fba5bd257c129847c70fbd4e45e41828079c4a282680528f3a50 already exists.."}
当然,根据该错误消息,该事务已经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动已经进行的原始交易。如果您想测试交易的创建,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硬币:
http://dev.blockcypher.com/#testing
(或通过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!
