OKhttpを使用して、Android=
OkHttp Recipes page から、このコードは画像をImgurにアップロードします。
private static final String IMGUR_CLIENT_ID = "...";
private static final MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png");
private final OkHttpClient client = new OkHttpClient();
public void run() throws Exception {
// Use the imgur image upload API as documented at https://api.imgur.com/endpoints/image
RequestBody requestBody = new MultipartBuilder()
.type(MultipartBuilder.FORM)
.addPart(
Headers.of("Content-Disposition", "form-data; name=\"title\""),
RequestBody.create(null, "Square Logo"))
.addPart(
Headers.of("Content-Disposition", "form-data; name=\"image\""),
RequestBody.create(MEDIA_TYPE_PNG, new File("website/static/logo-square.png")))
.build();
Request request = new Request.Builder()
.header("Authorization", "Client-ID " + IMGUR_CLIENT_ID)
.url("https://api.imgur.com/3/image")
.post(requestBody)
.build();
Response response = client.newCall(request).execute();
if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
System.out.println(response.body().string());
}
これをS3に適合させる必要がありますが、必要なクラスは同じでなければなりません。
OkHttp 2.1を取得し、MultipartBuilder.addFormDataPart()
を使用します。これは、ファイル名をパラメーターとして使用します。
/**
* Upload Image
*
* @param memberId
* @param sourceImageFile
* @return
*/
public static JSONObject uploadImage(String memberId, String sourceImageFile) {
try {
File sourceFile = new File(sourceImageFile);
Log.d(TAG, "File...::::" + sourceFile + " : " + sourceFile.exists());
final MediaType MEDIA_TYPE = sourceImageFile.endsWith("png") ?
MediaType.parse("image/png") : MediaType.parse("image/jpeg");
RequestBody requestBody = new MultipartBuilder()
.type(MultipartBuilder.FORM)
.addFormDataPart("member_id", memberId)
.addFormDataPart("file", "profile.png", RequestBody.create(MEDIA_TYPE_PNG, sourceFile))
.build();
Request request = new Request.Builder()
.url(URL_UPLOAD_IMAGE)
.post(requestBody)
.build();
OkHttpClient client = new OkHttpClient();
Response response = client.newCall(request).execute();
return new JSONObject(response.body().string());
} catch (UnknownHostException | UnsupportedEncodingException e) {
Log.e(TAG, "Error: " + e.getLocalizedMessage());
} catch (Exception e) {
Log.e(TAG, "Other Error: " + e.getLocalizedMessage());
}
return null;
}
compile 'com.squareup.okhttp3:okhttp:3.4.1'
RequestBodyで置き換え:
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("uploaded_file", filename, RequestBody.create(MEDIA_TYPE_PNG, sourceFile))
.addFormDataPart("result", "my_image")
.build();
okhttp 2.6.0の場合{
try {
File file = new File(Environment.getExternalStorageDirectory().getPath()+"/xxx/share/" + "ic_launcher.png");
String contentType = file.toURL().openConnection().getContentType();
RequestBody fileBody = RequestBody.create(MediaType.parse(contentType), file);
RequestBody requestBody = new MultipartBuilder()
.type(MultipartBuilder.FORM)
.addFormDataPart("fileUploadType","1")
.addFormDataPart("miniType",contentType)
.addFormDataPart("ext",file.getAbsolutePath().substring(file.getAbsolutePath().lastIndexOf(".")))
.addFormDataPart("fileTypeName","img")
.addFormDataPart("Filedata","ss.png",fileBody)
.build();
Request request = new Request.Builder()
.url(Contains.MULTIPARTY_POST)
.post(requestBody)
.build();
okHttpClient.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Request request, IOException e) {
runOnUiThread(new Runnable() {
@Override
public void run() {
tvGetNews.setText("upload fail");
}
});
}
@Override
public void onResponse(Response response) throws IOException {
runOnUiThread(new Runnable() {
@Override
public void run() {
tvGetNews.setText("upload success");
}
});
}
});
} catch (IOException e) {
e.printStackTrace();
}
}
Okhttp 4. *の場合は、MultipartBody.Builder
:
fun postMultipart(url: String, text: String, imagePath: String, imageFileName: String): okhttp3.Response? {
val file = File(imagePath)
val fileRequestBody = file.asRequestBody("image/jpeg".toMediaType())
val requestBody = MultipartBody.Builder()
.addFormDataPart("text", text)
.addFormDataPart("image", imageFileName, fileRequestBody)
.build()
val request = getRequestBuilder(url)
.post(requestBody)
.build()
val client = OkHttpClient()
client.newCall(request).execute().use { response ->
return response
}
}
