Android Retrofit 2文件上传不起作用
Android Retrofit 2文件上传不起作用
提问于 2016-11-14 20:14:37
我想开发一个应用程序，这是上传任何类型的文件到服务器。我拿到源代码了。但它只适用于图像。并且只上传小于2MB的图像文件。我想上传所有类型的文件。请帮帮我。我的代码如下所示。
MainActivity.java
public class MainActivity extends AppCompatActivity {
Service service;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = (Button) findViewById(R.id.btn_upload);
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();
// Change base URL to your upload server URL.
service = new Retrofit.Builder().baseUrl("http://192.168.1.4/work/filesharing/").client(client).build().create(Service.class);
if (btn != null) {
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String filePath1 = "/storage/emulated/0/gt.png";
File file = new File(filePath1);
RequestBody reqFile = RequestBody.create(MediaType.parse("*/*"), file);
MultipartBody.Part body = MultipartBody.Part.createFormData("uploaded_file", file.getName(), reqFile);
RequestBody name = RequestBody.create(MediaType.parse("text/plain"), "upload_test");
retrofit2.Call<okhttp3.ResponseBody> req = service.postImage(body, name);
req.enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) { }
@Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
t.printStackTrace();
Log.d("failure", "message = " + t.getMessage());
Log.d("failure", "cause = " + t.getCause());
}
});
}
});
}
}
}上传超过2MB的zip文件时将显示错误。

我在上传大图片或视频时也遇到了同样的问题。主要的问题是你在HttpLoggingInterceptor中使用body level，而logger在logcat中打印你的文件，触发了一个java.lang.OutOfMemoryError异常。
如果您不想禁用body level loggin，可以添加此代码，以避免在打印大文件内容时使用loggin。我创建了自己的HttpLoggingInterceptor，并添加了一个if条件，以便在content-length > 10Ks的情况下跳过正文登录。
HttpLoggingInterceptor是最后一个类，所以你不能重写它。您可以复制一份HttpLoggingInterceptor文件并替换以下原始代码：
if (!logBody || !hasRequestBody) {
logger.log("--> END " + request.method());
} else if (bodyEncoded(request.headers())) {
logger.log("--> END " + request.method() + " (encoded body omitted)");
} else {
Buffer buffer = new Buffer();
requestBody.writeTo(buffer);
//[...]使用以下代码：
if (!logBody || !hasRequestBody) {
logger.log("--> END " + request.method());
} else if (bodyEncoded(request.headers())) {
logger.log("--> END " + request.method() + " (encoded body omitted)");
} else if (requestBody.contentLength()>1024 * 10) { //>10Kb
logger.log("--> END " + request.method() + " (contentLength > 10Kb --> omitted)");
} else {
Buffer buffer = new Buffer();
requestBody.writeTo(buffer);
//[...]我希望这对任何人都有帮助。对不起，我的英语;)。

请降低日志记录级别或将其全部删除
查看此链接https://github.com/square/retrofit/issues/540上的JakeWharton回复
“通过调用.setLogLevel(RestAdapter.LogLevel.FULL)，您强制Retrofit将整个请求正文缓冲到内存中，以便它可以记录日志。这就是在堆栈跟踪中调用readBodyToBytesIfNecessary所做的事情。
只应在调试时启用此类日志记录。“

它与这个问题有关，https://github.com/square/retrofit/issues/540。你可以禁用你的拦截器Level.BODY。它可以在所有类型文件中工作，你有没有尝试过其他类型文件？
