问题:如何通过Restsharp使用multipart/form-data上载XML文件?
Question: How to upload an XML file using multipart/form-data with Restsharp?
问题:
我正在使用Peppol通过Codabox API发送发票.
我想将xml上传到其余服务.
其余服务本身受提供者Codabox的控制.
我提供了2种我希望做同样的方法.
I'm using Peppol for sending invoices using the Codabox API.
I want to upload an xml to the rest service.
The rest service itself is under control by the provider Codabox.
I have 2 methods provided who I expect to do the same.
首先使用Postman和httpclient,一切正常. 我想从使用restsharp方式的httpclient方法获得相同的结果.
First of all with Postman and httpclient, all the things works fine. I want to get the same from the httpclient method working using the restsharp way.
RestSharp版本:106.2.1
RestSharp version: 106.2.1
Restsharp的错误消息
response ="StatusCode:BadRequest,Content-Type:application/json, 内容长度:-1)内容=" {\文件\":[\没有文件 已提交.\]}"
response = "StatusCode: BadRequest, Content-Type: application/json, Content-Length: -1)" Content = "{\"file\":[\"No file was submitted.\"]}"
为了实现这一点,我在标头中有一个X-Software-Company密钥,提供了一个有效的xml文件,该文件是使用form-data(multipart/form-data)和身份验证凭据发送的.
For realizing this I have an X-Software-Company key in the header, providing a valid xml file that I send using form-data (multipart/form-data) and my authentication credentials.
期望的解决方案:
我想让Restsharp方法起作用,为什么现在不起作用. 因此,我提供的Restsharp方法需要执行与我提供的httpclient方法相同的操作.
I want to get the Restsharp method working and why it now doesn't work. So the Restsharp method I provided need to do the same as the httpclient method I provided.
我尝试过的事情:
Restsharp方法: ==>这是问题
public void TestUpload()
{
byte[] fileBytes = File.ReadAllBytes(@"C:\temp\test.xml");
var client = new RestClient("url for the rest call");
var request = new RestRequest(Method.POST);
request.AlwaysMultipartFormData = true;
request.Credentials = new NetworkCredential("username", "password");
request.AddHeader("X-Software-Company", "software key");
request.AddHeader("Content-Type", "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW");
request.AddFile("file", @"C:\temp\test.xml");
//request.AddHeader("content-type", "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW");
//request.AddParameter("multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW", "------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"file\"; filename=\"C:\\temp\\test.xml\"\r\nContent-Type: false\r\n\r\n\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--", ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
}
HttpClient方法: ==>正常工作
public void TestUploadHttpClient()
{
byte[] fileBytes = File.ReadAllBytes(@"C:\temp\test.xml");
using (HttpClient httpClient = new HttpClient())
{
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", "credentials");
httpClient.DefaultRequestHeaders.Add("X-Software-Company", "software key");
using (var content = new MultipartFormDataContent("boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW"))
{
content.Add(new StreamContent(new MemoryStream(fileBytes)), "file", "test.xml");
using (var message = httpClient.PostAsync("url for the rest call", content).Result)
{
var input = message.Content.ReadAsStringAsync().Result;
}
}
}
}
邮递员生成的代码:
如果我执行邮递员的请求,没有问题,如果我检查邮递员生成的Restsharp代码,它会给我:
If I do the request by Postman there is no problem, if I check the Restsharp code generated by postman it gives me:
var client = new RestClient("url for the rest call");
var request = new RestRequest(Method.POST);
request.AddHeader("Authorization", "Basic credentials");
request.AddHeader("Content-Type", "multipart/form-data");
request.AddHeader("X-Software-Company", "software key");
request.AddHeader("content-type", "multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW");
request.AddParameter("multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW", "------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"file\"; filename=\"C:\\temp\\test.xml\"\r\nContent-Type: false\r\n\r\n\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--", ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
我已经准确地测试了邮递员生成的代码,但是它不起作用.
I have exactly the code tested generated from postman but it doesn't work.
编辑2018-03-19:
RestSharp中可能存在的问题:添加的文件无法接收#1079
EDIT 2018-03-19:
Possible issue in RestSharp: Added files not being recieved #1079
临时解决方案:
我使用的是RestSharp版本v105.2.3,那么它的工作原理就像是一种魅力.
I'm using RestSharp version v105.2.3 then it works like a charm.
有人知道为什么restsharp方法不起作用以及如何解决吗?
Have anyone an idea why the restsharp method does not work and how to solve that?
推荐答案
尝试将内容类型参数放在AddFile方法中,如下所示:
Try to put the content type parameter in the AddFile method, like this:
request.AddFile("file", @"C:\temp\test.xml", "application/octet-stream");
