Question

如何在API Post方法C#中传递Json body？
需要将以下数据传递到 API 中：

{
"intent": "CAPTURE",
"purchase_units": [
    {
        "amount": {
            "currency_code": "USD",
            "value": "10"
        }
    }
],
"application_context": {
    "return_url": "https://example.com/return",
    "cancel_url": "https://example.com/cancel"
}

}

Answer 1

您可以使用 StringContent 将 JSON 传递到请求正文：

// Create the request body.
HttpContent content = new StringContent(jsonBody, Encoding.UTF8, "application/json");


// Send request.
HttpResponseMessage response = await httpClient.PostAsync(url, content);

变量 jsonBody 是这样定义的（记得转义字符）：

string jsonBody = @"{
       ""intent"": ""CAPTURE"",
       ""purchase_units"": [
                {
                    ""amount"": {
                        ""currency_code"": ""USD"",
                        ""value"": ""10""
                    }
                }
            ],
            ""application_context"": {
                ""return_url"": ""https://example.com/return"",
                ""cancel_url"": ""https://example.com/cancel""
            }
        }";

如果有帮助请告诉我。

那又如何

$.ajax({
    type: "POST",
    contentType: 'application/json; charset=utf-8',
    data: JSON.stringify({your_json_object}),
    url: 'PostAction',
    ... });

然后在你的控制器中

public HttpResponseMessage PostAction(..., [FromBody] your_json_objec){
}
