我在燒瓶中有一個項目來獲取參數并且它可以工作，如果我通過郵遞員打電話。但是如果我用 java 代碼來做，它會返回錯誤 400。燒瓶：@app.route('/predict', methods=["POST"])def predict():    print("\nPredict......")    print(request.form)    print(request.form['textToPredict'])    print("\nPredict......2")    print(request.form.get("textToPredict"))    #print("Text...."+request.form['textToPredict'].toString())    # new text to predict    text_to_predict = [request.form['textToPredict'].lower()] #[request.form.get('textToPredict')]  # ["asmatica desde infancia ex fumante 15 am dopc em uso de o2 ha 1 ano em uso de alenia 400 /12  e formoterol 12    2 x dia mvdiminuido sra brn f 2 t s/s cta  rx pfp"]  # este deve retornar CID Z00    #print("Text....:"+str(text_to_predict))    # count_vect gera as posi??es dos vetores de cada palavra do texto.    new = count_vect.transform(text_to_predict)    # carrega o modelo treinado    loaded_model = cPickle.load(open(fname, 'rb'))    # faz a predi??o do novo texto de entrada    result = loaded_model.predict(new)    print(result)    # accuracy_score(y_test, result)    json_dict = request.get_json()    text = ''.join(result)    textPredicted = text    data = {'textPredicted': textPredicted}    return jsonify(data), 200java的輸出（打印燒瓶代碼）：Predict......ImmutableMultiDict([('{"textToPredict":"coriza"}', '')])127.0.0.1 - - [22/Oct/2018 16:07:34] "POST /predict HTTP/1.1" 400 -郵遞員的輸出（打印 FLASK 代碼）：Predict......ImmutableMultiDict([('textToPredict', 'coriza, dificuldade em respirar, febre, dor no corpo')])coriza, dificuldade em respirar, febre, dor no corpoPredict......2coriza, dificuldade em respirar, febre, dor no corpo['J06 ']127.0.0.1 - - [22/Oct/2018 16:20:00] "POST /predict HTTP/1.1" 200 -所以，看起來我的錯誤是在發送帖子時，它是由 java 代碼組成的。我不明白錯誤的原因。在我看來，參數在到達燒瓶時是不正確的，根據它提供的輸出。我需要一些幫助來解決這個問題。謝謝你。
