我已经尝试了两天了解如何复制卷曲请求以将图像添加到我的Craftar图像识别集合中。我能够创建一个Item,但是设置multipart-data代码的方法让我失望了。 Craftar仅提供如何发布图像文件以将其附加到集合Item的cURL语句。
我已经尝试过使用RequestB.in和Postman来查看我在消息传输中可以看到的内容,但是没有okHTTP方法的组合似乎可以解决问题。我很难过。我已尝试将“image / png”和“application / octet-stream”作为我的MediaTypes。当我使用Postman向其发送测试请求时,RequestB.in显示“application / octet-stream”。以下是它显示的消息信息。
这是我试图用Java复制的cURL语句。
curl -X POST'https://my.craftar.net/api/v0/image/api_key=123456789abcdefghijk123456789abcdefghijk'-F“item = / api / v0 / item / d05924dde1784787a3d6b815e2b1cd69 /” - F“file=@back_cover.jpg”
这是我的代码:
public class OkHttpHandler extends AsyncTask<String, Void, String> {
OkHttpClient client = new OkHttpClient();
@Override
protected String doInBackground(String... params) {
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File file = new File("/storage/emulated/0/Pictures/BlissBotSenderImages/kaytiandkristoffer.jpg");
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("item", "/api/v0/item/d05924dde1784787a3d6b815e2b1cd69/")
.addFormDataPart("file","kaytiandkristoffer.jpg",
(RequestBody.create (MEDIA_TYPE_PNG, file)))
.build();
Request request = new Request.Builder()
.url(postImageUrl)
.post(requestBody)
.build();
try {
Response response = client.newCall(request).execute();
return response.body().string();
} catch (Exception e) {
e.printStackTrace();
}
以下是 RequestB.in 成功邮寄邮递员的消息详情:

有时会发生问题。沿着这条线的某处我意外地在端点地址中插入了一个无关的字符。我解决了这个问题,上面的代码只是找到了。
