Java Android：通过Http Get或Post请求以字节[]的形式发送图像

Java Android：通过Http Get或Post请求以字节[]的形式发送图像,java,android,soap,httprequest,Java,Android,Soap,Httprequest,我需要将图像上传到web服务器，它要求ImageContent在文档中的字节[]中，它说的是base64Binary，但我尝试了base64编码字符串，但没有使用 ByteArrayOutputStream stream = new ByteArrayOutputStream(); Bitmap resizedBitmap = Bitmap.createScaledBitmap(thumbnail, 150, 150, false); resizedBitmap.compress(Bitmap.

我需要将图像上传到web服务器，它要求ImageContent在文档中的字节[]中，它说的是base64Binary，但我尝试了base64编码字符串，但没有使用

ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap resizedBitmap = Bitmap.createScaledBitmap(thumbnail, 150, 150, false);
resizedBitmap.compress(Bitmap.CompressFormat.PNG, 100,stream);
byte[] byteArray = stream.toByteArray();
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
new ImageUpload().execute(encoded);

那是我的班级：

你能在你的chrome控制台上试试这个并告诉输出吗

xmlhttp=new XMLHttpRequest();
    var url = '/_mobfiles/CLS_Account.asmx/UploadImage?';
    var base64 ='R0lGODlhDwAPAKECAAAAzMzM/////wAAACwAAAAADwAPAAACIISPeQHsrZ5ModrLlN48CXF8m2iQ3YmmKqVlRtW4MLwWACH+H09wdGltaXplZCBieSBVbGVhZCBTbWFydFNhdmVyIQAAOw=='
    xmlhttp.open("GET",url + 'ImageContent='+base64+'&imageExtenstion=gif',true);
    xmlhttp.send();
    console.log(xmlhttp.response)

ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap resizedBitmap = Bitmap.createScaledBitmap(thumbnail, 150, 150, false);
resizedBitmap.compress(Bitmap.CompressFormat.PNG, 100,stream);
byte[] byteArray = stream.toByteArray();
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
new ImageUpload().execute(encoded);

也试试这个。如果这也失败了，你必须检查服务器。至少提供负责处理此问题的服务器方法

xmlhttp=new XMLHttpRequest();
var url = '/_mobfiles/CLS_Account.asmx/UploadImage?';
var base64 ='R0lGODlhDwAPAKECAAAAzMzM/////wAAACwAAAAADwAPAAACIISPeQHsrZ5ModrLlN48CXF8m2iQ3YmmKqVlRtW4MLwWACH+H09wdGltaXplZCBieSBVbGVhZCBTbWFydFNhdmVyIQAAOw=='
xmlhttp.open("POST",true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send('ImageContent="'+base64+'"&imageExtenstion="gif"');
console.log(xmlhttp)

ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap resizedBitmap = Bitmap.createScaledBitmap(thumbnail, 150, 150, false);
resizedBitmap.compress(Bitmap.CompressFormat.PNG, 100,stream);
byte[] byteArray = stream.toByteArray();
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
new ImageUpload().execute(encoded);

使用Get请求并使用

var base64 ='R0lGODlhDwAPAKECAAAAzMzM%2F%2F%2F%2F%2FwAAACwAAAAADwAPAAACIISPeQHsrZ5ModrLlN48CXF8m2iQ3YmmKqVlRtW4MLwWACH%2BH09wdGltaXplZCBieSBVbGVhZCBTbWFydFNhdmVyIQAAOw%3D%3D'

ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap resizedBitmap = Bitmap.createScaledBitmap(thumbnail, 150, 150, false);
resizedBitmap.compress(Bitmap.CompressFormat.PNG, 100,stream);
byte[] byteArray = stream.toByteArray();
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
new ImageUpload().execute(encoded);

我相信这应该行得通。我真的很抱歉，我不该犯这样一个愚蠢的错误/

我没有办法，只能把整个肥皂信封都寄出去

ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap resizedBitmap = Bitmap.createScaledBitmap(thumbnail, 150, 150, false);
resizedBitmap.compress(Bitmap.CompressFormat.PNG, 100,stream);
byte[] byteArray = stream.toByteArray();
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
new ImageUpload().execute(encoded);

因此，在后台线程AsyncTask中，我在执行时调用了callSOAPWebServiceString数据

ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap resizedBitmap = Bitmap.createScaledBitmap(thumbnail, 150, 150, false);
resizedBitmap.compress(Bitmap.CompressFormat.PNG, 100,stream);
byte[] byteArray = stream.toByteArray();
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
new ImageUpload().execute(encoded);

从UI线程

ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap resizedBitmap = Bitmap.createScaledBitmap(thumbnail, 150, 150, false);
resizedBitmap.compress(Bitmap.CompressFormat.PNG, 100,stream);
byte[] byteArray = stream.toByteArray();
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
new ImageUpload().execute(encoded);

背景呢

ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap resizedBitmap = Bitmap.createScaledBitmap(thumbnail, 150, 150, false);
resizedBitmap.compress(Bitmap.CompressFormat.PNG, 100,stream);
byte[] byteArray = stream.toByteArray();
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
new ImageUpload().execute(encoded);

@Override
        protected String doInBackground(String... params) {
            callSOAPWebService(params[0]);
            return null;
        }

callSOAPWebService如下所示

ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap resizedBitmap = Bitmap.createScaledBitmap(thumbnail, 150, 150, false);
resizedBitmap.compress(Bitmap.CompressFormat.PNG, 100,stream);
byte[] byteArray = stream.toByteArray();
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
new ImageUpload().execute(encoded);

private boolean callSOAPWebService(String data) {
        OutputStream out = null;
        int respCode;
        boolean isSuccess = false;
        URL url;
        HttpURLConnection httpURLConnection = null;
        try {
            url = new URL(GetData.NonOpDomain);
            httpURLConnection = (HttpURLConnection) url.openConnection();

                httpURLConnection.setRequestProperty("Content-length", getReqData(data).length + "");
                httpURLConnection.setReadTimeout(100 * 1000);
                // httpURLConnection.setConnectTimeout(10 * 1000);
                httpURLConnection.connect();
                out = httpURLConnection.getOutputStream();
                if (out != null) {
                    out.write(getReqData(data));
                    out.flush();
                }
                respCode = httpURLConnection.getResponseCode();
                Log.e("respCode", ":" + respCode);
            } while (respCode == -1);

            // If it works fine
            if (respCode == 200) {
                try {
                    InputStream responce = httpURLConnection.getInputStream();
                    String str = convertStreamToString(responce);
                    System.out.println(".....data....." + str);
                    InputStream is = new ByteArrayInputStream(str.getBytes("UTF-8"));
                    XmlPullParserFactory xmlFactoryObject = XmlPullParserFactory.newInstance();
                    XmlPullParser myparser = xmlFactoryObject.newPullParser();
                    myparser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false);
                    myparser.setInput(is, null);
                    parseXMLAndStoreIt(myparser);
                } catch (Exception e1) {
                    e1.printStackTrace();
                }
            } else {
                isSuccess = false;
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (out != null) {
                out = null;
            }
            if (httpURLConnection != null) {
                httpURLConnection.disconnect();
                httpURLConnection = null;
            }
        }
        return isSuccess;
    }

希望它能对将来的人有所帮助

我应该在哪里写呢？在浏览器上试试，yyy指的是图像类型，xxxx指的是base64编码的图像，在这里试试并分享。使用一个小图像来快速。它显示图像OK。您可以使用您的技术尝试一个1~KB左右的非常小的图像。这是谁的服务器？一般来说，GET请求有大小限制，而将图像转换为base 64本身会大幅增加大小，所以您的大小可能会有问题。尝试手动访问链接。预期的行为是什么？它应该返回包含自动生成的图像名称Get…wWACH+h09wdgltaxplzcbiesbvbgvhzcbtbfydfnhdmvyiqaaow==&imageExtenstion=gif 500的字符串对象的xml内部服务器错误状态：404状态文本：确定上载：XMLHttpRequestUpload with credentials:false proto:XMLHttpRequestand when putin url返回System.ArgumentException:无法将R0LGODLhdwapakecaaaaAaAaAaAaAaAaAaAaAaCiispeqhsrz5ModrlLn48cxf8m2iq3ymmkqvlrtw4mlwAch h09wdgltaxplzcbiesBvHzcBwFyDmVyQaaow==转换为System.Byte。参数名称：type-->System.FormatException:输入字符串的格式不正确。谢谢我的朋友，我将尝试与我的web提供商联系，我标记了答案是否有效？现在您应该只编码您的base64字符串。
