值不会从一个控制器传递到另一个控制器

Question

Passing data between two separate controllers. I have the following in my first file:

public ActionResult Report(string sDate, string eDate)
{   
    var client = new WebClient();
    string avgRatesCos = String.Format(client.DownloadString("http://localhost/api/values/1?sBookingDate={0}&eBookingDate={1}"), sDate, eDate);
    string maxAvgRates = String.Format(client.DownloadString("http://localhost/api/values/2?sBookingDate={0}&eBookingDate={1}"), sDate, eDate);
    string minAvgRates = String.Format(client.DownloadString("http://localhost/api/values/3?sBookingDate={0}&eBookingDate={1}"), sDate, eDate);

in my second file/controller my values in 'sBookingDate' and 'eBookingDate' show up as {0} and {1} instead of values being passed from the first controller:

public QueryResponse Get(int id, string sBookingDate, string eBookingDate)
{
    Console.WriteLine(sBookingDate, eBookingDate);
}

Answer 1

You've got your String.Format and your client.DownloadString operations backwards. So you're literally just requesting the {0} as the parameter... then calling String.Format on the result of the call to the action/controller.

Instead of

string avgRatesCos = String.Format(client.DownloadString("http://localhost/api/values/1?sBookingDate={0}&eBookingDate={1}"), sDate, eDate);

it should be

string avgRatesCos = client.DownloadString(String.Format("http://localhost/api/values/1?sBookingDate={0}&eBookingDate={1}", sDate, eDate));

Answer 2

尝试

string minAvgRates = client.DownloadString("http://localhost/api/values/3?sBookingDate=" +sDate + "&eBookingDate="+eDate);
