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" \
-H "Authorization: Bearer Access-Token" \
-F 'input={
  "evidences": [
{
  "evidence_type": "PROOF_OF_FULFILLMENT",

  ]
};type=application/json' \
-F 'file1=@NewDoc.pdf'

C#代码及生成命令

cmd = "curl -v -X POST https://api.paypal.com/v1/customer/disputes/" + dirName + "/provide-evidence "
+ "-H \"Content-Type: multipart/related; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW\" "
+ "-H \"Authorization: Bearer " + token + "\" "
+ "-F 'input={\\\"evidences\\\": [{\\\"evidence_type\\\": \\\"PROOF_OF_FULFILLMENT\\\",\\\"evidence_info\\\": "
+ "{\\\"tracking_info\\\": [{\\\"carrier_name\\\": \\\"" + expressType + "\\\",\\\"tracking_number\\\": \\\"" + expressNo + "\\\"}]},"
+ "\\\"notes\\\": \\\"" + expressTxt + "\\\"}]};type=application/json' "
+ "-F 'file1=@\\\"" + filePng.FullName + "\\\"'";

curl -v -X POST https://api.paypal.com/v1/customer/disputes/PP-D-79024859/provide-evidence -H "Content-Type: multipart/related; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW" -H "Authorization: Bearer A21AAMsI4ZYkaJbKfvCWwaqXc98PSq71uZoVqhJOzVy-RzLIt76922GcGHmdKIK1MhCPWupKXq1C0Teny49LiCNrH7U4jIs3w" -F 'input={\"evidences\": [{\"evidence_type\": \"PROOF_OF_FULFILLMENT\",\"evidence_info\": {\"tracking_info\": [{\"carrier_name\": \"CN_CHINA_POST_EMS\",\"tracking_number\": \"LZ273548120CN\"}]},\"notes\": \"test\"}]};type=application/json' -F 'file1=@\"C:\Users\Administrator\Desktop\PP\PP-D-79024859\LZ273548120CN.png\"'

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。

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.)

引用 4 楼 亚特兰蒂斯DE 的回复:

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.

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

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

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

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。

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);
    }
}
