Question

我正在尝试将图片发送到我的API。但是在使用MultipartEntity StringBody时，由于不推荐使用StringBody（String），我会收到错误。

我不工作。我是Android sending image to Server via MultipartEntity - setting Content-type?的样本。

这是代码：

try {

    List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add(new BasicNameValuePair("api_key", api_key));
    params.add(new BasicNameValuePair("access_token", access_token));

    API api = new API(mApiKey, mApiSecret);        


    HttpClient client = new DefaultHttpClient();
    HttpPost postMethod = new HttpPost("MY API URL");
    File file = new File(imagePath);
    MultipartEntity entity = new MultipartEntity();
    FileBody contentFile = new FileBody(file);

    StringBody api_key       = new StringBody(mApiKey);
    StringBody access_token  = new StringBody(access_token);

    entity.addPart("api_key", api_key);
    entity.addPart("hash", access_token);
    entity.addPart("image", contentFile);

    postMethod.setEntity(entity);
    client.execute(postMethod);



} catch (Exception e) {
    e.printStackTrace();
}

Answer 1

不推荐使用用于创建StringBody的新实例的构造函数。

而不是

new StringBody(mApiKey);

你应该使用StringBody构造函数和第二个参数ContentType

new StringBody(mApiKey, ContentType.TEXT_PLAIN);

有关详细信息，请参阅：

和

Answer 2

StringBody：

 entity.addPart("api_key", new StringBody(mApiKey,ContentType.TEXT_PLAIN));

MultipartEntity：

检查：The type MultipartEntity is deprecated

Android StringBody（String）已弃用
