HTTP/1.1 415 不支持的媒体类型答案

【问题标题】：HTTP/1.1 415 Unsupported Media TypeHTTP/1.1 415 不支持的媒体类型
【发布时间】：2013-01-16 22:52:00
【问题描述】：

我想使用以下代码通过我的 android 应用程序上传视频。

HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(uri);
MultipartEntity entity = new MultipartEntity();
ContentBody input = new FileBody(file);
ContentBody name  = new StringBody("VID_20130201_162220.3gp");
ContentBody description = new StringBody("Test Description");
entity.addPart("input",input);
entity.addPart("name",name);
entity.addPart("description",description);
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost);
HttpEntity httpEntity = response.getEntity();

httpClient.execute() 方法返回响应时，显示“HTTP/1.1 415 Unsupported Media Type”

我也尝试从 HttpPost 中删除 MultipartEntry，但仍然出现相同的错误。

谁能告诉我可能是什么问题。

【问题讨论】：

问题似乎出在服务器端
一个 iphone 应用程序正在使用相同的服务，所以我不认为这可能是服务器问题...
在服务器级别检查两个请求（iphone 和 android），看看有什么不同。服务器拒绝请求是有原因的

【解决方案1】：

您需要告诉服务器允许 3gp 媒体类型。如果您使用的是 Apache，您可以通过将 AddType video/3gpp .3gp 添加到服务器的配置文件来完成此操作。（我认为这是正确的语法）。

【讨论】：

我也为 .mp4 和 .avi 文件尝试过同样的代码。它对这些文件抛出了同样的错误

【解决方案2】：

试试这个解决方案：它适用于大多数类型的文件。

private DefaultHttpClient mHttpClient;
Context context;
public String error = "";

//Contrutor para que metodos possam ser usados fora de uma activity
public HTTPconector(Context context) {
    this.context = context;

    mHttpClient = new DefaultHttpClient(params);
}

        multipartEntity.addPart("Image", new FileBody(file));
        httppost.setEntity(multipartEntity);
        mHttpClient.execute(httppost, new PhotoUploadResponseHandler());
    }
    catch (Exception e)
    {
        Log.e(HTTPconector.class.getName(), e.getLocalizedMessage(), e);
        e.getStackTrace();
        error = e.getMessage();
    }
}
