[英]PostAsync with two strings using HttpClient and HttpResponseMessage
我正在嘗試使用HttpClient和HttpResponseMessage用兩個字符串執行Http POST調用。
這是我的帖子的代碼:
public async Task Convert()
{
string url = "http://localhost:5000/convert/files";
string stringValue1 = "test1";
string stringValue2 = "test2";
var x = await ConvertFiles(stringValue1, stringValue2, url);
}
public async static Task<string> ConvertFiles(string s1, string s2, string webAddress)
{
HttpClient client = new HttpClient();
StringContent sc = new StringContent("");
HttpResponseMessage response = await client.PostAsync(webAddress, sc);
string content = await response.Content.ReadAsStringAsync();
Console.WriteLine("Result: " + content);
return content;
}
我相信我必須使用StringContent,但是我不確定如何使用(這就是為什么它為空)。
這是我的HttpPost呼叫:
[HttpPost("/mshdf/import")]
public string ConvertFiles([FromBody]string s1, [FromBody]string s2)
{
Console.WriteLine("string1: " + s1);
Console.WriteLine("string2: " + s2);
return "woo";
}
我剛剛開始使用HttpClient和HttpResponseMessage。 現在,該呼叫沒有發生-我猜這是由於我沒有正確發送字符串s1和s2所致。
這不是唯一的方法,但應該起作用。 假定使用了Nuget包System.Net.Http v4.1.0,而不是可以從“引用”添加的程序集。
public async static Task<string> ConvertFiles(string s1, string s2, string webAddress)
{
using(HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Cleare();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));
List<KeyValuePair<string,string>> formFields = new List<KeyValuePair<string,string>>();
formFields.Add(new KeyValuePair<string,string>("s1", s1));
formFields.Add(new KeyValuePair<string,string>("s2", s2));
var formContent = new FormUrlEncodedContent(formFields);
HttpResponseMessage response = await client.PostAsync(webAddress, formContent);
string content = await response.Content.ReadAsStringAsync();
Console.WriteLine("Result: " + content);
return content;
}
}
[HttpPost("/mshdf/import")]
public string ConvertFiles(FormDataCollection data)
{
Console.WriteLine(data.Get("s1"));
Console.WriteLine(data.Get("s2"));
return "woo";
}
弄清楚了。 感謝CrowCoder的帖子。
我最終制作了包含我的價值觀的字典。
public async static Task<string> ConvertFiles(string s1, string s2, string webAddress)
{
Dictionary<string, string> jsonValues = new Dictionary<string, string>();
jsonValues.Add("string1", "anyStringValue1");
jsonValues.Add("string2", "anyStringValue2");
HttpClient client = new HttpClient();
StringContent sc = new StringContent(JsonConvert.SerializeObject(jsonValues), UnicodeEncoding.UTF8, "application/json");
HttpResponseMessage response = await client.PostAsync(webAddress, sc);
string content = await response.Content.ReadAsStringAsync();
Console.WriteLine("Result: " + content);
return content;
}
現在,您只需要使用動態類型來訪問string1和string2,如下所示:
[HttpPost("/mshdf/import")]
public string ConvertFiles([FromBody]dynamic jsonObject)
{
Console.WriteLine("string1: " + jsonObject.string1);
Console.WriteLine("string2: " + jsonObject.string2);
return "woo";
}
