我无法使用fogbugz API 上传附件。我遵循了fogbugz 文档，但也许我错了。发生的错误是：Ex.Message = "字典中不存在给定的键。"

今天早上我遇到了同样的错误，但在查看 FBApi.cs 的源代码时能够修复它。

简而言之，上传文件的代码依赖于在上传文件时存在的特定密钥，而该文件在任何地方都没有明确解释。

这些键是：

  • 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，"multipart/form-data"根据FogBugz XML API 文档）
  • data（即，byte[]文件内容的实际内容）。

一旦提供了这些，异常就消失了，我的测试文件已成功上传。

出于说明目的，我在下面包含了我的工作代码示例，

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:\path\to\test.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);
