前一陣子我自己架設了一個tinode的IM服務器,

web直接可以運行

但是安卓版本的一直報錯，

具體信息為：

No subjectAltNames on the certificate match

問了作者，作者竟然把我的問題直接刪除了，還是自己調試代碼吧。畢竟源碼面前，了無秘密；

一、代碼地址

GitHub - tinode/tindroid: Tinode chat client application for Android

我從release部分下載了0.20.9版本源碼

二、更改源碼配置

1）根目錄下的build.gradle有2處需要更改，主要是版本信息，非git版本無從提取，隨便設置一下

static def gitVersionCode() {// If you are not compiling in a git directory and getting an error like// [A problem occurred evaluating root project 'master'. For input string: ""]// then just return your manually assigned error code like this:// return 12345def process = "git rev-list --count HEAD".execute()return 12345 }// Use current git tag as a version name. // For example, if the git tag is 'v0.20.0-rc1' then the version name will be '0.20.0-rc1'. static def gitVersionName() {// If you are not compiling in a git directory, you should manually assign version name:// return "MyVersionName"def process = "git describe --tags".execute()// Remove trailing CR and remove leading 'v' as in 'v1.2.3'return "1.2.3" }

2）app下面的build.gradle有3處需要修改

2.1）程序使用googleService，需要去官網注冊一下相關的資料，自己注冊一個新的應用，下載得到google-services.json，這個文件放置于app目錄；

2.2）google-services.json中我們注冊了一個應用的名字，這文件中有個package_name替換原來的應用ID，否則編譯不過

applicationId "com.birdschat.cn"

2.3）創建證書，文件放置于源碼同級目錄，比如我的：

../robinkeys/key.keystore

在根目錄下添加一個配置文件，叫keystore.properties，內容大概如下：

keystoreFile=../robin_keys/key.keystore keystoreAlias=key.keystore keystorePassword=123456 keyPassword=123456

并根據自己配置文件中的參數名，設置一下build.gradle：

signingConfigs {release {storeFile file(keystoreProperties['keystoreFile'])storePassword keystoreProperties['keystorePassword']keyAlias keystoreProperties['keyAlias']keyPassword keystoreProperties['keyPassword']}}

這樣應該就可以編譯了！！

3）取消客戶端WebSocket 的SSL雙向認證

但是運行后，設置了自己的服務器，以及使用加密模式，無法注冊或者登錄，

主要是我們的證書需要有域名，并且是申請來的，也就是有CA認證的，而不是自己生成的，不然無法實現雙向驗證，這主要是為了防止中間人攻擊；

但是我們往往就是自己內部試用，不需要這么麻煩，

需要對SDK部分代碼進行更該，參考：java websocket及忽略證書_nell_lee的博客-CSDN博客_websocket 忽略證書

更改后的代碼如下：Connection.java 全文

這樣，登錄就OK了；

4）設置服務器默認參數

將服務器的鏈接參數預先設置好為我們需要的：

4.1) 地址與端口：全文搜索“:6060”字樣,在資源文件res/strings.xml中更改：

<string name="emulator_host_name" translatable="false">119.0.0.1:6060</string>

同時，將build.gradle的相關位置做更改，自動生成相關的資源文件

buildTypes {debug {resValue "string", "default_host_name", '"119.0.0.0:6060"'}release {resValue "string", "default_host_name", '"api.tinode.co"'minifyEnabled trueshrinkResources trueproguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'signingConfig signingConfigs.release}

在同樣在資源中更改為自己的地址和端口；

4.2）默認使用https，更改TindroidApp.java

將返回的默認的參數設置為true

public static boolean getDefaultTLS() {//return !isEmulator();return true;}

編譯好了就可以用了！

5) 還需要更改LargeFileHelper，

在完成第4步驟后，發送小文件正常，大文件比如5兆，就報錯了，?

java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

這說明大文件使用其他的方法發送時驗證證書失敗了，果然，SDK中使用了單獨的一個輔助類單獨開了一個鏈接POST發送大文件，參考如下鏈接：Trust anchor for certification path not found異常解決方法_HZYXN的博客-CSDN博客

更改后的代碼如下：

package co.tinode.tinodesdk;import com.fasterxml.jackson.core.JsonParseException; import com.fasterxml.jackson.core.JsonParser; import com.fasterxml.jackson.core.JsonToken; import com.fasterxml.jackson.databind.JsonNode; import com.fasterxml.jackson.databind.ObjectMapper;import org.jetbrains.annotations.NotNull; import org.jetbrains.annotations.Nullable;import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.DataOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.net.HttpURLConnection; import java.net.URL; import java.security.SecureRandom; import java.util.HashMap; import java.util.Map; import java.util.concurrent.CancellationException;import co.tinode.tinodesdk.model.MsgServerCtrl; import co.tinode.tinodesdk.model.ServerMessage; // import javax.net.ssl.HttpsURLConnection; import javax.net.ssl.SSLHandshakeException; import javax.net.ssl.*; import java.net.Socket; import java.net.URI; import java.security.cert.CertificateException; import java.security.cert.X509Certificate;public class LargeFileHelper {private static final int BUFFER_SIZE = 65536;private static final String TWO_HYPHENS = "--";private static final String BOUNDARY = "*****" + System.currentTimeMillis() + "*****";private static final String LINE_END = "\r\n";private final URL mUrlUpload;private final String mHost;private final String mApiKey;private final String mAuthToken;private final String mUserAgent;private boolean mCanceled = false;private int mReqId = 1;public LargeFileHelper(URL urlUpload, String apikey, String authToken, String userAgent) {mUrlUpload = urlUpload;mHost = mUrlUpload.getHost();mApiKey = apikey;mAuthToken = authToken;mUserAgent = userAgent;handleSSLHandshake();}// robin add herepublic static void handleSSLHandshake() {try {TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {public X509Certificate[] getAcceptedIssuers() {return new X509Certificate[0];}@Overridepublic void checkClientTrusted(X509Certificate[] certs, String authType) {}@Overridepublic void checkServerTrusted(X509Certificate[] certs, String authType) {}}};SSLContext sc = SSLContext.getInstance("TLS");// trustAllCerts信任所有的證書sc.init(null, trustAllCerts, new SecureRandom());HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {@Overridepublic boolean verify(String hostname, SSLSession session) {return true;}});} catch (Exception ignored) {}}// Upload file out of band.

編譯后，發送大文件不再報錯了。

6）還需要發送圖片時，無法正常彈出圖片瀏覽器框

調試過程中發現，是由于我們更改了應用程序的ID，造成默認的路徑發生了變化，在讀取臨時文件時候發生了錯誤，所以需要更改一下相關的路徑：provider_paths.xml

<?xml version="1.0" encoding="utf-8"?> <paths><external-path name="tindroid_downloads" path="./Download" /><external-path name="tindroid_images" path="Android/data/com.birdschat.cn/files/Pictures" /> </paths>

這里應該與applicationId中設置的一樣才行。

其實這里的錯誤，經過分析代碼，是因為MessagesFragment.java 在試圖發送圖片時候，程序會嘗試新建一個文件用于保存照片，所以才會使用了臨時文件，而這里由于邏輯問題，在真機上每次即使不拍照也會產生垃圾數據，所以決定禁用了拍照，選擇時候反而更加流程；

7）聊天頭像丟失的問題

這個其實也是認證的問題，主要是在ChatsAdapter.java中bing函數設置avatar時候，使用了piccaso來下載對應的圖片，但是不能直接改；因為在TindroidApp.java中初始化時候設置了Okhttp3下載工具，并且設置了相對鏈接的轉換方式，

所以應該改TindroidApp.java
