代码:
public HttpResponseMessage GetFileContent()
{
var md = new BaseModel();
try
{
platType = "1";
md = GeneratePDF();
}
catch (Exception ex)
{
md.AppMsg = ex.Message;
}
var response = Request.CreateResponse(HttpStatusCode.OK);
var data = JsonConvert.SerializeObject(md);
response.Content = new StringContent(data, Encoding.UTF8);
LogHelper.WriteInfo("*************************************************************************************");
LogHelper.WriteInfo("GetFileContent_data:" + data);
LogHelper.WriteInfo("GetFileContent_response.Content:" + response.Content);
LogHelper.WriteInfo("GetFileContent_Headers:" + response.Headers);
LogHelper.WriteInfo("GetFileContent_IsSuccessStatusCode:" + response.IsSuccessStatusCode);
LogHelper.WriteInfo("GetFileContent_StatusCode:" + response.StatusCode);
LogHelper.WriteInfo("GetFileContent_ReasonPhrase:" + response.ReasonPhrase);
LogHelper.WriteInfo("GetFileContent_RequestMessage:" + response.RequestMessage);
LogHelper.WriteInfo("GetFileContent_Version:" + response.Version);
LogHelper.WriteInfo("*************************************************************************************");
return response;
}

不同的参数请求的返回结果:

返回结果(日志中记录的一切正常):
正常返回结果(第一次请求):
开始本次请求:20190611 06:22:31
{"AppMsg":"获取文件成功","AppCode":1,"Success":true,"Data":{"FileName":"f6faedad315a4a2c94bae52aedc7d06c.pdf","TmpPDFUrl":"http://127.0.0.1:9031/PrintService/DownloadFile?fileName=f6faedad315a4a2c94bae52aedc7d06c.pdf","TmpId":"30","TmpType":"在职证明","ECode":"R10119069658"}}
本次请求结束:20190611 06:22:40
本次请求耗时9155.8157ms
非正常返回结果(第二次请求):
开始本次请求:20190611 06:22:52

本次请求结束:20190611 06:22:54
本次请求耗时1997.5708ms

日志中记录的一切正常,但是用HttpPost请求之后,返回的结果一个正常,一个为空。其中GeneratePDF()有两种实现方式,一种是word直接转的PDF,该访问方式完全正常,另外一种,反射访问的类库,但是返回结果为空。

折磨了两天了,烦请大神给点建议,看看到底怎么回事?
