c#JSON发布

我无法解决这个问题。如果我在HTTP Post之前使用NewtonSoft将对象序列化为JSON，我将从REST服务收到400。如果我只是将JSON作为字符串发布，那么在下面的代码中，它将作为“jsonx”工作。但是，如果我比较字符串“json”和“jsonx”，它们是相同的

public async Task<String> TransferAsync(String fromAddress, Int64 amount, String toAddress, String assetId)
{
    Models.CoinPrism.TransferRequest request = new CoinPrism.TransferRequest()
    {
        fees = 1000,
        from = fromAddress,
    };

    request.to[0] = new CoinPrism.Transfer()
    {
        address = toAddress,
        amount = amount,
        asset_id = assetId
    };

    String json = Newtonsoft.Json.JsonConvert.SerializeObject(request);
    String jsonX = "{  \"fees\": 1000,  \"from\": \"1zLkEoZF7Zdoso57h9si5fKxrKopnGSDn\",  \"to\": [    {      \"address\": \"akSjSW57xhGp86K6JFXXroACfRCw7SPv637\",      \"amount\": \"10\",      \"asset_id\": \"AHthB6AQHaSS9VffkfMqTKTxVV43Dgst36\"    }  ]}";

    Uri baseAddress = new Uri("https://api.coinprism.com/");

    using (var httpClient = new HttpClient { BaseAddress = baseAddress })
    {
        using (var content = new StringContent(jsonX, System.Text.Encoding.Default, "application/json"))
        {
            using (var response = await httpClient.PostAsync("v1/sendasset?format=json", content))
            {
                string responseData = await response.Content.ReadAsStringAsync();
                return responseData;
            }
        }
    }
}

错误的原因是它们是相同的字符串，但编码不同

您发送的字符串编码错误

1-序列化后，将字符串转换为ANSI编码（例如）

---

2-

using（var content=new StringContent（jsonX，System.Text.Encoding.ANSI，“application/json”）

如果

json

等于

jsonX

，那么你会得到同样的结果。你有没有试过fiddler查看发送的原始内容？你是手动编写“jsonX”的吗？我认为它可能与“json”不同例如，amount是Int64，在“json”中有“amount”：10，而在“jsonx”中有“amount”：“10”，就像一个字符串一样

public class TransferRequest
{
    public Int64 fees { get; set; }

    public String from { get; set; }

    public Transfer[] to { get; set; }

    public TransferRequest(Int32 n = 1)
    {
        this.to = new Transfer[n];
    }

    public TransferRequest(Transfer transfer)
    {
        this.to = new Transfer[1];
        this.to[0] = transfer;
    }
}

public class Transfer
{
    public String address { get; set; }

    public Int64 amount { get; set; }

    public String asset_id { get; set; }
}
