PostTransaction failed: Invalid api encoding

[guotie]

I use the Spend method in helper.go, I got error

{
    "reason": "Invalid api encoding"
}

The tx and post request is following:

curl -X POST "http://192.168.1.122:3013/v2/transactions" -H "accept: application/json" -H "Content-Type: application/json" -d "{ \"tx\": \"tx_77HAufwc2o474Dk39cz92mJZwWfThZYoAd3M7wka9KY7dWeeeBzxpYTwAB3iReJ5XAUKtyWS3YXdRsX3MDX1yUmck2ewFhwcVB7nWybnBtLwopyvGfh6gLxEk2oY4H2cF9Lv5ZwBVdgGjyYn4UdkeadFBv8fEbaaorFfbaqWMyD15ikQjC6jWZjk6aF4Erq57DfJT1d3s5coeck9ikD3aKHSXj3ZcHVo6ujevkRVBiwPauHPqkVBB\"}"

How to solve it

[guotie]

I change the tx encode from base58 to base64, and the error changed to:

 {"reason":"Invalid tx"}

the tx is:

tx_+K0LAfhCuECVAoKRHAA0340xaWjT794Jek19ClmfDIDUn7bZJzXqCFgc6fQQ/ryNNpw0FF/YPXU8JuHVERtCtUnZTdsbPKIKuGX4YwwBoQEZSfC6lpjA3coVQ76+43LwY86L6TBhcQFcMh3xOD2Yr6EBL4SNMItRNjNretVJr40fLGgJQOksMEqmhCFeFzAfg++IRWORgkT0AACGvv5vZyAAgi48iCg1/awAI5AAgBwMi5E=

老兄 中国人？ 就是一个加密算法用错了 encodeP里面用的是base58 然而tx需要base64

see: https://github.com/aeternity/protocol/blob/master/epoch/api/api_encoding.md

用base58时，报"Invalid api encoding"

改成base64之后报"Invalid tx"

老外的项目真tmd不靠谱

兄弟我的没毛病了 你是不是fee没调大 fee得为17000+

[wx-shi]

我们交易所都上线了，完全没毛病

[wx-shi]

只是错误返回不明显 我当初fee也是默认为1 结果也报Invalid tx

[guotie]

fee设置成17000，还是 Invalid tx

[guotie]

thank you very much. @wx-shi

It my fault, I got wrong nonce.
