调用示例

1、RestClient请求(form-data)

public static string GetFile(Stream stream, string title, string fileType)
        {
            Dictionary<string, string> headerParam = new Dictionary<string, string>();
            headerParam.Add("x-xx", "s");
            headerParam.Add("x-xxx", "ss");
            headerParam.Add("x-xxxx", "sss");
            Dictionary<string, object> bodyData = new Dictionary<string, object>();
            bodyData.Add("title", title);
            bodyData.Add("fileType", fileType);
            var url = "xxxxxxx";
            var redata = PostInfoData(url, headerParam, bodyData, "file", stream.CopyTo, title + "." + fileType);
            return redata;
        }

2、RestClient请求(application/json)

public static string GetCreateInfo() 
        {
            Dictionary<string, string> headerParam = new Dictionary<string, string>();
            headerParam.Add("x-x", "s");
            headerParam.Add("x-xx", "ss");
            headerParam.Add("x-xxx", "sss");
            string jsondata =  "{\"conditions\":{ \"requestname\":\"" + "" + "\",\"workflowIds\":\"xx\"},\"pageNo\":\"" + 1 + "\",\"pageSize\":\"" + 1000 + "\",\"workId\":\"xx\",\"appId\":\"ssss\"}";
            var url = "sssssssss";
            var redata = PostInfoData(url, headerParam, jsondata);
            return redata;
        }

3、RestClient请求(form-data)，返回byte[]

public static byte[] GetDownloadfile(string documentxx)
        {
            Dictionary<string, string> headerParam = new Dictionary<string, string>();
            headerParam.Add("x-x", "s");
            headerParam.Add("x-xx", "ss");
            headerParam.Add("x-xxx", "sss");
            Dictionary<string, object> bodyData = new Dictionary<string, object>();
            bodyData.Add("documentxx", documentxx);
            bodyData.Add("connet", "xxxxxx");
            var url = "sssssssss";
            var redbyte = PostInfoData(url, headerParam, bodyData, RestSharp.Method.GET);
            return redbyte;
        }
