【问题描述】：
我无法使用 Text Translation API 获取语言名称。我通过这种方法获得了可用的语言：
public async Task<List<string>> GetLanguagesForTranslateAsync()
{
string requestUri = "https://api.microsofttranslator.com/v2/http.svc/GetLanguagesForTranslate";
string accessToken = await this.auth.GetTokenAsync();
string response = await this.GetAsync(requestUri, accessToken);
XDocument xml = XDocument.Parse(response);
List<string> languages = new List<string>();
foreach (XElement element in xml.Root.Descendants())
{
languages.Add(element.Value);
}
return languages;
}
private async Task<string> GetAsync(string url, string bearerToken)
{
using (HttpClient httpClient = new HttpClient())
{
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", bearerToken);
HttpResponseMessage response = await httpClient.GetAsync(url);
return await response.Content.ReadAsStringAsync();
}
}
在这种情况下，我得到一个带有“en”、“es”、“fr”或“zh-CHT”等语言代码的 XML，但我想得到“english”、“spanish”、“french”或“中国传统的）”。看着the documentation这个方法我试过了：
public async Task<List<string>> GetLanguageNamesAsync(string locale, List<string> languageCodes)
{
string requestUri = "https://api.microsofttranslator.com/v2/http.svc/GetLanguageNames";
string content = $"locale=en&languageCodes=en,es,fr,zh-CHT";
string accessToken = await this.auth.GetTokenAsync();
string response = await this.PostAsync(requestUri, accessToken, content);
XDocument xml = XDocument.Parse(response);
List<string> languages = new List<string>();
foreach (XElement element in xml.Root.Descendants())
{
languages.Add(element.Value);
}
return languages;
}
private async Task<string> PostAsync(string url, string bearerToken, string content)
{
using (HttpClient httpClient = new HttpClient())
{
httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", bearerToken);
HttpResponseMessage response = await httpClient.PostAsync(url, new StringContent(content));
return await response.Content.ReadAsStringAsync();
}
}
我收到此请求的响应：
请求错误
错误状态代码： 'InternalServerError'

真正的 XML 响应：

你知道发生了什么吗？我还需要什么其他东西才能提出请求吗？
