paypal官方接口

curl -v -X POST https://api.sandbox.paypal.com/v1/customer/disputes/PP-D-27803/provide-evidence \

-H "Content-Type: multipart/related; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW" \

重点帮我看下 C# 生成调用命令有没有问题？是不是字符串没转义好或者格式不对。

一看你代码语法好还是处于很低的水平啊是不是你编辑器 IDE版本太低了还用这样的拼接方式? 高版本的C#中都是 $语法了.

用Http请求可行?



using (var httpClient = new HttpClient())
{
    using (var request = new HttpRequestMessage(new HttpMethod("POST"), "https://api.sandbox.paypal.com/v1/customer/disputes/PP-D-27803/provide-evidence"))
    {
        request.Headers.TryAddWithoutValidation("Authorization", "Bearer Access-Token"); 

        var multipartContent = new MultipartFormDataContent();
        multipartContent.Add(new StringContent("{\n  \"evidences\": [\n{\n  \"evidence_type\": \"PROOF_OF_FULFILLMENT\",\n  \"evidence_info\": {\n  \"tracking_info\": [\n    {\n    \"carrier_name\": \"FEDEX\",\n    \"tracking_number\": \"122533485\"\n    }\n  ]\n  },\n  \"notes\": \"Test\"\n}\n  ]\n}"), "input");
        multipartContent.Add(new ByteArrayContent(File.ReadAllBytes("NewDoc.pdf")), "file1", Path.GetFileName("NewDoc.pdf"));
        request.Content = multipartContent; 

        var response = await httpClient.SendAsync(request);
    }
}

提醒一下，多看一下开发文档。我经常写接口，文档和测试都好重要的。

两个问题，，第一个在内容参数外，尽量用单引号。减少转义第二个，双引号放到C#代码里直接转义，并在转义前将代码测试一遍，然后以参数的形式修改内容

我用的是2.0 只是临时小项目没讲究直接写，http请求我晚点试下谢谢

学习下Postman吧,可以导入Curl请求,并生成C#的请求代码(以及其他语言的版本.)

postman有用但生成的curl命令不对，json类型指定type=application/json ，没了
