【HttpClient】调用QQ小程序安全内容检测接口

前言

QQ小程序内容安全-图片检测

调用接口的代码

此处仅贴出核心调用的代码，IFormFile对象由Controller中传递，access_token需要自己去获取，HttpClient需要自己去注入

private readonly HttpClient _client;
public async Task<string> GetQQImgSecCheck(string access_token, IFormFile file)
{
string r = string.Empty;
string url = "https://api.q.qq.com/api/json/security/ImgSecCheck?access_token=" + access_token;
using (Stream fs = file.OpenReadStream())
{
//文件生成的字节数组
byte[] fileBytes = new byte[fs.Length];
fs.Read(fileBytes, 0, fileBytes.Length);
//ByteArray内容，需要重新对Header中的ContentType和ContentDisposition赋值
var byteFileCOntent= new ByteArrayContent(fileBytes);
byteFileContent.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
byteFileContent.Headers.ContentDisposition = ContentDispositionHeaderValue.Parse($"form-data; name=\"media\"; filename=\"{file.FileName}\"");
//使用MultipartFormDataContent对象，对应为Content-Type = form-data
MultipartFormDataContent cOntent= new MultipartFormDataContent();
content.Add(byteFileContent, "media", file.FileName);
HttpResponseMessage response = await _client.PostAsync(url, content);
if (response.IsSuccessStatusCode)
r = await response.Content.ReadAsStringAsync();
}
return r;
}
