我需要将图片上传到网络服务器，并且它需要ImageContent在文件中的字节[]，它说base64Binary，但我尝试了base64编码的字符串，没有用
这是我的班级：
private class background extends AsyncTask<byte[],Void,String> {
String url = "http://www.sample.com/_mobfiles/CLS_Account.asmx/UploadImage";
String charset = "UTF-8";
String param1 = "jpg";
@Override
protected String doInBackground(byte[]... params) {
try {
String query = String.format("ImageContent=%s&imageExtenstion=%s", params[0], URLEncoder.encode(param2, charset));
URLConnection connection = new URL(url + "?" + query).openConnection();
connection.setRequestProperty("Accept-Charset", charset);
InputStream response = connection.getInputStream();
for (Map.Entry<String, List<String>> header : connection.getHeaderFields().entrySet()) {
System.out.println(header.getKey() + "=" + header.getValue());
}
String contentType = connection.getHeaderField("Content-Type");
String charset = null;
for (String param : contentType.replace(" ", "").split(";")) {
if (param.startsWith("charset=")) {
charset = param.split("=", 2)[1];
break;
}
}
if (charset != null) {
try (BufferedReader reader = new BufferedReader(new InputStreamReader(response, charset))) {
for (String line; (line = reader.readLine()) != null;) {
System.out.println(line);
}
}
}
else {
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
int nRead;
byte[] data = new byte[16384];
while ((nRead = response.read(data, 0, data.length)) != -1) {
buffer.write(data, 0, nRead);
}
buffer.flush();
byte[] arr = buffer.toByteArray();
String decoded = new String(arr, "UTF-8");
System.out.println(decoded);
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
返回（java.io.FileNotFoundException）
和Base64编码返回（java.net.ProtocolException：意外状态行：对象已移动）
这是Doc：
HTTP GET
以下是HTTP GET请求和响应示例。显示的占位符需要替换为实际值。
GET /_mobfiles/CLS_Account.asmx/UploadImage?ImageContent=base64Binary&imageExtenstion=string HTTP/1.1
Host: www.sample.com
并且响应就像
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length
<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">string</string>
HTTP POST
以下是HTTP POST请求和响应示例。显示的占位符需要替换为实际值。
POST /_mobfiles/CLS_Account.asmx/UploadImage HTTP/1.1
Host: www.sample.com
Content-Type: application/x-www-form-urlencoded
Content-Length: length
ImageContent=base64Binary&imageExtenstion=string
并且响应就像
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length
<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">string</string>

您可以在Chrome控制台中尝试此操作并告诉输出。
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)
试试这个。如果这也失败了，你必须检查服务器。 Atleast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)
使用获取请求并使用
var base64 ='R0lGODlhDwAPAKECAAAAzMzM%2F%2F%2F%2F%2FwAAACwAAAAADwAPAAACIISPeQHsrZ5ModrLlN48CXF8m2iQ3YmmKqVlRtW4MLwWACH%2BH09wdGltaXplZCBieSBVbGVhZCBTbWFydFNhdmVyIQAAOw%3D%3D'
我确信这应该有效。我真的很抱歉我的坏我应该没有犯这样一个愚蠢的错误/

我找不到方法，只能发送整个SOAP信封
所以从后台线程AsyncTask我执行时调用了callSOAPWebService(String data)
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);
和背景
@Override
protected String doInBackground(String... params) {
callSOAPWebService(params[0]);
return null;
}
，callSOAPWebService如下
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();
do {
httpURLConnection.setRequestMethod("POST");
httpURLConnection.setRequestProperty("Connection", "keep-alive");
httpURLConnection.setRequestProperty("Content-Type", "text/xml");
httpURLConnection.setRequestProperty("SendChunked", "True");
httpURLConnection.setRequestProperty("UseCookieContainer", "True");
HttpURLConnection.setFollowRedirects(false);
httpURLConnection.setDoOutput(true);
httpURLConnection.setDoInput(true);
httpURLConnection.setUseCaches(true);
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;
}
和辅助方法
public volatile boolean parsingComplete = true;
public void parseXMLAndStoreIt(XmlPullParser myParser) {
int event;
String text = null;
try {
event = myParser.getEventType();
while (event != XmlPullParser.END_DOCUMENT) {
String name = myParser.getName();
switch (event) {
case XmlPullParser.START_TAG:
break;
case XmlPullParser.TEXT:
text = myParser.getText();
break;
case XmlPullParser.END_TAG:
if (name.equals("UploadImageResult")) {
uploadedImage = text;
uploadedImage = uploadedImage.replace("\"", "");
}
break;
}
event = myParser.next();
}
parsingComplete = false;
} catch (Exception e) {
e.printStackTrace();
}
}
public static String createSoapHeader() {
String soapHeader;
soapHeader = "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
+ "<soap:Envelope "
+ "xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\""
+ " xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\""
+ " xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"" + ">";
return soapHeader;
}
public static byte[] getReqData(String data) {
StringBuilder requestData = new StringBuilder();
requestData.append(createSoapHeader());
requestData.append("<soap:Body>" + "<UploadImage" + " xmlns=\"http://example.org/\">" + "<ImageContent>").append(data).append("</ImageContent>\n").append("<imageExtenstion>jpg</imageExtenstion>").append("</UploadImage> </soap:Body> </soap:Envelope>");
Log.d("reqData: ", requestData.toString());
return requestData.toString().trim().getBytes();
}
private static String convertStreamToString(InputStream is)
throws UnsupportedEncodingException {
BufferedReader reader = new BufferedReader(new InputStreamReader(is,
"UTF-8"));
StringBuilder sb = new StringBuilder();
String line;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
希望它能帮助将来的某个人
