Question

我有以下用于Phonegap的代码将图像上传到PHP，它可以工作，但是完成后，我想重定向到index.html，尽管控制似乎永远不会返回到执行ft.upload（）的位置。 -上传完成后，我需要怎么做？

<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
    $("#post_id").val("8");
    var ls_token    = get_token("token");
    alert( ls_token );
    $("#token_id").val( ls_token );     
    //
    // Wait for PhoneGap to load
    //
    document.addEventListener("deviceready", onDeviceReady, false);

    // PhoneGap is ready
    //
    function onDeviceReady() {
        // Retrieve image file location from specified source
        navigator.camera.getPicture(uploadPhoto,
                                    function(message) { alert('get picture failed'); },
                                    { 
                                            quality: 50, 
                                            destinationType: navigator.camera.DestinationType.FILE_URI,
                                            sourceType: navigator.camera.PictureSourceType.PHOTOLIBRARY                                         }
        );
    }

    function uploadPhoto(imageURI) {
        var options = new FileUploadOptions();
        options.fileKey="file";
        //options.fileKey="img";
        options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
        options.mimeType="image/jpeg";
        var params = new Object();
        params.value1 = "test";
        params.value2 = "param";
        options.params = params;
        //options.chunkedMode = false;

        var ft = new FileTransfer();
        ft.upload(imageURI, "http://example.com/add_pictures/", win, fail, options );
        // similar behavior as an HTTP redirect
        window.location.replace("index.html");      // <-- not executed..

    }
    function win(r) {
        alert("Code = " + r.responseCode);
        alert("Response = " + r.response);
        console.log("Sent = " + r.bytesSent);
        // similar behavior as an HTTP redirect
        window.location.replace("index.html");      // <-- not executed..
    }

    function fail(error) {
        alert("An error has occurred: Code = " + error.code);
        alert("upload error source " + error.source);
        alert("upload error target " + error.target);
    }

}); 
</script>

我设法自己整理了一下……最终。我使用“ phonegap create ..”创建了一个新项目-还更新了cordova版本。在config.xml中，我添加了以下内容：

<edit-config target="NSCameraUsageDescription" file="*-Info.plist" mode="merge">
    <string>need camera access to take pictures</string>
</edit-config>

<edit-config target="NSPhotoLibraryUsageDescription" file="*-Info.plist" mode="merge">
    <string>need photo library access to get pictures from there</string>
</edit-config>

<edit-config target="NSLocationWhenInUseUsageDescription" file="*-Info.plist" mode="merge">
    <string>need location access to find things nearby</string>
</edit-config>

<edit-config target="NSPhotoLibraryAddUsageDescription" file="*-Info.plist" mode="merge">
    <string>need photo library access to save pictures there</string>
</edit-config>

然后在manifest.xml中添加：

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

也根据这篇文章： https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-file-transfer/ 在人们进行了一些研究之后，不赞成使用文件传输： XMLHttpRequest，所以我将传输代码更改为：

        var fd = new FormData();
        fd.append("file", file);
        fd.append("id","88");
 var posts = new XMLHttpRequest();
posts.onreadystatechange = function() { // listen for state changes
  if (posts.readyState == 4 && posts.status == 200) { // when completed we can move away
    window.location = "done.html";
  }
}
posts.open("POST",  'http://example.com/test1.php',   true);
posts.send(fd);

不确定其中哪一个真正解决了问题。我猜想在尝试原始项目中的内容时，发生了一些更改或添加，从而使它不满意

完成后，phonegap图片上传重定向
