我正在尝试将编码的图像字符串发布到改造后的方法...调试后我在从图库中选择的图像的调试中得到了很长的字符串......提交后我可以在调试器中看到图像的长字符串编码.. ..在邮递员中,当我检查时我显示 profile_pic: " "为空...

需要帮忙

如果我使用这样的端点,我不会崩溃:

   @FormUrlEncoded
@POST("update")
fun useredit(
    @Header("access_token") token: String,
    @Field("first_name") first_name:String,

    @Field("last_name") last_name:String,
    @Field("email") email:String,

    @Field("dob") dob:String,
    @Field("phone_no") phone_no: String,
    @Field("profile_pic") profile_pic:String

):Call<LoginResponse>

响应代码:

profile = findViewById<View>(R.id.profilepic) as ImageView

    profile?.setOnClickListener(View.OnClickListener {

        val intent = Intent()
        intent.type = "image/*"
        intent.action = Intent.ACTION_GET_CONTENT
        startActivityForResult(intent, IMAGE)
    })
    editsubmit.setOnClickListener {

        val first_name = firstname.text.toString().trim()
        val last_name = lastname.text.toString().trim()

        val email = emailregister.text.toString().trim()
        val phone = phoneno.text.toString().trim()

        val profile =convertToString()!!
        val token: String =
            SharedPrefManager.getInstance(
                applicationContext
            ).user.access_token.toString()

        RetrofitClient.instance.useredit(token,first_name,last_name,email,edittext1.text.toString(),phone,profile)
            .enqueue(object : Callback<LoginResponse> {
                override fun onFailure(call: Call<LoginResponse>, t: Throwable) {
                    Log.d("res", "" + t)
                }
                override fun onResponse(
                    call: Call<LoginResponse>,
                    response: Response<LoginResponse>
                ) {
                    var res = response
                    Log.d("response check ", "" + response.body()?.status.toString())
                    if (res.body()?.status==200) {
                        Toast.makeText(
                            applicationContext,
                            res.body()?.message,
                            Toast.LENGTH_LONG
                        ).show()
                        Log.d("kjsfgxhufb",response.body()?.status.toString())
                    }
                    else
                    {
                        try {
                            val jObjError =
                                JSONObject(response.errorBody()!!.string())
                            Toast.makeText(
                                applicationContext,
                                jObjError.getString("message")+jObjError.getString("user_msg"),
                                Toast.LENGTH_LONG
                            ).show()
                        } catch (e: Exception) {
                            Toast.makeText(applicationContext, e.message, Toast.LENGTH_LONG).show()
                            Log.e("errorrr",e.message)
                        }
                    }

                }
            })
    }
}
private fun convertToString(): String? {
      val byteArrayOutputStream = ByteArrayOutputStream()
    bitmap?.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream)
    val imgByte: ByteArray = byteArrayOutputStream.toByteArray()

    return android.util.Base64.encodeToString(imgByte, android.util.Base64.NO_WRAP )
}

override fun onActivityResult(
    requestCode: Int,
    resultCode: Int,
    data: Intent?
) {
    super.onActivityResult(requestCode, resultCode, data)
    if (requestCode == IMAGE && resultCode == Activity.RESULT_OK && data != null) {
        val path: Uri? = data.data
        try {
            bitmap = MediaStore.Images.Media.getBitmap(contentResolver, path)
            profile?.setImageBitmap(bitmap)
        } catch (e: IOException) {
            e.printStackTrace()
        }
    }
}

我在调试器上看到长字符串,但在邮递员上看不到

后来我尝试了这个-->

我的端点:

   @Multipart
@POST("update")
fun useredit(
    @Header("access_token") token: String,
    @Part("first_name") first_name:String,

    @Part("last_name") last_name:String,
    @Part("email") email:String,

    @Part("dob") dob:String,
    @Part("phone_no") phone_no: String,
    @Part ("profile_pic")profile_pic: MultipartBody.Part?

):Call<LoginResponse>

活动响应代码:-

profile?.setOnClickListener(View.OnClickListener {

        val intent = Intent()
        intent.type = "image/*"
        intent.action = Intent.ACTION_GET_CONTENT
        startActivityForResult(intent, IMAGE)
    })
    editsubmit.setOnClickListener {

        val first_name = firstname.text.toString().trim()
        val last_name = lastname.text.toString().trim()

        val email = emailregister.text.toString().trim()
        val phone = phoneno.text.toString().trim()

        val profile =convertToString()!!

                        Log.d("kjsfgxhufb",response.body()?.status.toString())
                    }
                    else
                    {
                        try {
                            val jObjError =
                                JSONObject(response.errorBody()!!.string())
                            Toast.makeText(
                                applicationContext,
                                jObjError.getString("message")+jObjError.getString("user_msg"),
                                Toast.LENGTH_LONG
                            ).show()
                        } catch (e: Exception) {
                            Toast.makeText(applicationContext, e.message, Toast.LENGTH_LONG).show()
                            Log.e("errorrr",e.message)
                        }
                    }

                }
            })
    }
}
private fun convertToString(): String? {
      val byteArrayOutputStream = ByteArrayOutputStream()
    bitmap?.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream)
    val imgByte: ByteArray = byteArrayOutputStream.toByteArray()

    return android.util.Base64.encodeToString(imgByte, android.util.Base64.NO_WRAP )
}

override fun onActivityResult(
    requestCode: Int,
    resultCode: Int,
    data: Intent?
) {
    super.onActivityResult(requestCode, resultCode, data)
    if (requestCode == IMAGE && resultCode == Activity.RESULT_OK && data != null) {
        val path: Uri? = data.data
        try {
            bitmap = MediaStore.Images.Media.getBitmap(contentResolver, path)
            profile?.setImageBitmap(bitmap)
        } catch (e: IOException) {
            e.printStackTrace()
        }
    }
}

}

好吧,我从上面的代码中崩溃了——> java.lang.IllegalArgumentException:使用 MultipartBody.Part 的 @Part 参数不能在注释中包含部件名称。(参数#7)

您可以尝试更改以下内容,因为您发送的所有内容都是字符串,因此多部分文件并不理想。只需使用请求正文发送它,让我们看看服务器如何响应。

@Multipart
@POST("update")
fun useredit(
    @Header("access_token") token: String,
    @PartMap Map<String, RequestBody> partMap
):Call<LoginResponse>

无论你打电话到哪里,都这样做。

// create a map of data to pass along
RequestBody first_name = RequestBody.create(MediaType.parse("text/plain"),"your name here"); 
RequestBody last_name = RequestBody.create(MediaType.parse("text/plain"),"your last name here");
RequestBody email = RequestBody.create(MediaType.parse("text/plain"),"your email here");
RequestBody dob = RequestBody.create(MediaType.parse("text/plain"),"your dob here");
RequestBody phone_no = RequestBody.create(MediaType.parse("text/plain"),"your phone no here");
RequestBody profile_pic = RequestBody.create(MediaType.parse("text/plain"),"your picture base64 string here");
    
Map<String, RequestBody> map = new HashMap<>();  
map.put("first_name", first_name);  
map.put("last_name", last_name);  
map.put("email", email);
map.put("dob", dob);
map.put("phone_no", phone_no);
map.put("profile_pic", profile_pic);

然后将其传递给调用函数

 RetrofitClient.instance.useredit(token, map)//some code follows

编辑:

还需要以正确的格式发送图像 base64,例如

data:image/jpeg;base64,/9j/4AAQSkZJRgABAQ.........

或使用以下方法将其转换为 base64 编码。

private fun convertToString(): String? {
val byteArrayOutputStream = ByteArrayOutputStream()
bitmap?.compress(Bitmap.CompressFormat. JPEG, 100, byteArrayOutputStream)
val imgByte: ByteArray = byteArrayOutputStream.toByteArray()

return android.util.Base64.encodeToString(imgByte, android.util.Base64.NO_WRAP )
}

将您的地图从 java 更改为 kotlin 实现,如下面的代码所示

val map: MutableMap<String, RequestBody> = HashMap() 
map["first_name"] = first_name
map["last_name"] = last_name
map["email"] = email
map["dob"] = dob
map["phone_no"] = phone_no
map["profile_pic"] = profile_pic
