Fogbugz API-无法上载文件(c#实现)

Question

我无法使用fogbugz API上传附件。我遵循了fogbugz文档，但也许我错了什么。出现的错误是：示例消息="字典中不存在给定的密钥。"

今天早上我遇到了同样的错误，但在查看FBApi.cs.的源代码时，我修复了它

简而言之，上传文件的代码依赖于上传文件时出现的特定密钥，而这些密钥在任何地方都没有明确解释。

这些密钥是：

• name（即File1）
• filename（要上传的磁盘上文件的路径--不言自明）
• contenttype（我使用过，根据FogBugzXMLneneneba API文档"multipart/form-data"）
• data（即文件内容的实际byte[]）

一旦提供了这些，异常就消失了，我的测试文件也成功上传了。

为了便于说明，我在下面包含了一个我的工作代码示例，

Dictionary<String, String> caseOptions = new Dictionary<String, String>();
Dictionary<String, Byte[]> PDF = new Dictionary<String,Byte[]>();
Dictionary<String, Byte[]>[] files = new Dictionary<String, Byte[]>[1];
System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
// below will log into our FogBugz URL to use the FBApi
FogBugz.Init();
string fileName = @"C:pathtotest.pdf";
// setup any necessary values
caseOptions.Add("sEvent", "Attaching PDF file");
caseOptions.Add("ixBug", "9999");
// setup required keys
PDF.Add("name", encoding.GetBytes("File1"));
PDF.Add("filename", encoding.GetBytes(fileName));
PDF.Add("contenttype", encoding.GetBytes("multipart/form-data"));
PDF.Add("data", File.ReadAllBytes(fileName));
files[0] = PDF;
FogBugz.fb.XCmd("edit", caseOptions, files);
