[英]How to call Web API (App Service) remotely
我需要通過uri從AppService調用API。
這是我的API:
public ApiOutputBase Test_AddStudent(string name, int age, string address)
{
return new ApiOutputBase
{
Result = new Result { Status = true, Message = "OK,Test_AddStudent Done!" },
OuputValues = new List<object>() { name, age, address }
};
}
我用這個函數來稱呼它:
public async Task<bool> TestCallApi()
{
var client = new HttpClient { BaseAddress = new Uri("http://localhost/") };
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var testJson = "{\r\n \"name\": \"MyName\",\r\n \"age\": 25,\r\n \"address\": \"MyAddress\"\r\n}";
HttpResponseMessage response = await client.PostAsync("api/services/myApp/commonLookup/Test_AddStudent", new StringContent(testJson));
// Call api success
if (response.IsSuccessStatusCode)
{
}
return true;
}
我使用Swagger成功調用了Test_AddStudent
。 該testJson
從揚鞭復制當我打電話Test_AddStudent
成功。
之后,我使用Swagger調用了TestCallApi
沒有任何錯誤,但是當我嘗試調試HttpResponseMessage
的值時,它顯示了此錯誤:
{
StatusCode: 400,
ReasonPhrase: 'Bad Request',
Version: 1.1,
Content: System.Net.Http.StreamContent,
Headers: {
Pragma: no-cache
Cache-Control: no-store, no-cache

Content-Length: 405
Content-Type: application/json; charset=utf-8

}
}
我錯過了什么嗎?
我終於找到了根本原因:我將錯誤的輸入傳遞給api:
錯誤:
var testJson = "{\r\n \"name\": \"MyName\",\r\n \"age\": 25,\r\n \"address\": \"MyAddress\"\r\n}";
HttpResponseMessage response = await client.PostAsync("api/services/myApp/commonLookup/Test_AddStudent", new StringContent(testJson));
正確:
HttpResponseMessage response = await client.PostAsync("api/services/myApp/commonLookup/Test_AddStudent?name=MyName&age=25&address=MyAdress", "");
