Send data is a JSON string to js while happen error

[carl1990]

when I call the Method

webView.callHandler(jsHandlerName, data, new CallBackFunction() {
@OverRide
public void onCallBack(String dataFromJS) { } });

and data is a json String as :

{"misp_rate": 0.0, "miss_rate": 0.0, "reading_difficulty": 3, "sentence": "What's your name?", "sentscore": 7.729825044290912, "hypsent": "", "redu_rate": 100.0, "score": 0.0, "frame_stats": [{"end": 0.0, "fluency": "ok", "start": 0.0, "score": 0.0, "word": "WHAT'S", "class": "missing"}, {"end": 0.0, "fluency": "ok", "start": 0.0, "score": 0.0, "word": "YOUR", "class": "missing"}, {"end": 0.0, "fluency": "ok", "start": 0.0, "score": 0.0, "word": "NAME", "class": "missing"}], "result": [{"end": 0.0, "fluency": "ok", "start": 0.0, "score": 0.0, "word": "WHAT'S", "class": "missing"}, {"end": 0.0, "fluency": "ok", "start": 0.0, "score": 0.0, "word": "YOUR", "class": "missing"}, {"end": 0.0, "fluency": "ok", "start": 0.0, "score": 0.0, "word": "NAME", "class": "missing"}], "overall_score_grade": [1.0, 0.16716503179825531, 0.04837733590220021, 0.005763443891519606, 0.0009540585770522334, 6.666328219118981e-20, 0.0, 0.0, 0.0], "frames": 0.0, "vocal_score": 47.2583396248}

JSON.stringify() 兼容性有些问题。试试换

function o2s(object){ if(null==object)return "null"; var type = typeof object; if('object'== type){ if (Array == object.constructor) type = 'array'; else if (RegExp == object.constructor) type = 'regexp'; else type = 'object'; } switch(type){ case 'undefined': case 'unknown': return; break; case 'function': case 'boolean': case 'regexp': return object.toString(); break; case 'number': return isFinite(object) ? object.toString() : 'null'; break; case 'string': return '"' + object.replace(/(\\|\")/g,"\\$1").replace(/\n|\r|\t/g, function(){ var a = arguments[0]; return (a == '\n') ? '\\n': (a == '\r') ? '\\r': (a == '\t') ? '\\t': "" }) + '"'; break; case 'object': var pp="";var value =""; var results = []; try{ for (var property in object) { pp=object[property]; value = o2s(pp); if (value !== undefined) results.push('"'+property + '":' + value); }; } catch(e){ } return '{' + results.join(',') + '}'; break; case 'array': var results = []; if(object.length>=0){ for(var i = 0; i < object.length; i++){ var value = o2s(object[i]); if (value !== undefined) results.push(value); }; return '[' + results.join(',') + ']'; } else{ for(k in object) { var kk=k; var value = o2s(object[k]); if (value !== undefined) results.push('"'+kk+'":'+value); } return '{' + results.join(',') + '}'; } break; } }

这个后来我是在 iframe.src 做了一次编码解决的，其中有些字符串没有做编码导致后边转码会失败的

function _fetchQueue() {
    console.log("++++++++++sendMessageQueue:"+sendMessageQueue);
        var messageQueueString = JSON.stringify(sendMessageQueue);
        console.log("++++++++++messageQueueString:"+messageQueueString);
        sendMessageQueue = [];
        //add by hq
        if (isIphone()) {
            return messageQueueString;
            //android can't read directly the return data, so we can reload iframe src to communicate with java
        } else if (isAndroid()) {
            var url = CUSTOM_PROTOCOL_SCHEME + '://return/_fetchQueue/' + messageQueueString;
            console.log("++++++++++url:"+url);
            messagingIframe.src = encodeURI(url); //修改的地方
        }
    }
