Question

我是堆栈溢出的新手。希望我正确地提出问题。

我必须在Java中转换下面的命令。有了这个，我还必须在 multipart / form-data 中将位图上传到服务器。我尝试使用http urlconnection，但我不断收到400 Bad Request错误。我不确定curl命令中使用的语法以及如何在java中进行转换。任何帮助将不胜感激。

curl -X POST 'https://my.craftar.net/api/v0/image/?api_key=123456789abcdefghijk123456789abcdefghijk' 
-F "item=/api/v0/item/4fe672886ec142f6ab6d72d54acf046f/" 
-F "file=@back_cover.jpg"

您可以查看链接here以获取任何说明。

这是我迄今为止所尝试过的：

private String webAddressToPost = "https://my.craftar.net/api/v0/image/?api_key=123456789abcdefghijk123456789abcdefghijk";
    URL url = new URL(webAddressToPost);
                    HttpURLConnection conn = NetCipher.getHttpsURLConnection(url);


                    conn.setRequestMethod("POST");
                    conn.setRequestProperty("Connection", "Keep-Alive");
                    conn.setRequestProperty("Content-Type", "multipart/form-data");

                    MultipartEntity entity = new MultipartEntity(
                            HttpMultipartMode.BROWSER_COMPATIBLE);
                    ByteArrayOutputStream bos = new ByteArrayOutputStream();
                    bitmap.compress(CompressFormat.PNG, 100, bos);
                    byte[] data = bos.toByteArray();
                    ByteArrayBody bab = new ByteArrayBody(data, "test.png");
                    entity.addPart("item",new StringBody(ITEM_ID);
                    entity.addPart("file", bab);
                    conn.addRequestProperty("Content-length", entity.getContentLength() + "");

参见此示例

https://github.com/square/okhttp/wiki/Recipes#posting-a-multipart-request

class Login:
    def __init__(self, user, password):
        self.user = user
        self.password = password

    def as_tuple(self):
        return self.user, self.password

login_details = Login(user='a', password='b')
print(login_details.as_tuple())
>> ('a', 'b')

转换为
