我正在向服务器发送AJAX请求,以在数据库中创建一个新条目,然后返回创建的条目的ID。运行代码时,控制台会显示#Initialize list to hold all of the accuracy data
all_accuracies = []
#For each training set group
for group_number in range(len(train_set_sizes)):
#For each ANN in training set group
for i in range(num_ANNs):
#Initialize group_accuracies list
group_accuracies = []
#--------------Generate a training set--------------------------------
#Initialize train_set lists
train_set_examples = []
train_set_labels = []
#randomly select indices to pull train set examples
example_select_indices = np.random.randint(0,55000,size=train_set_sizes[group_number])
#For number of images in the appropriate training set group
for j in range(train_set_sizes[group_number]):
random_index = example_select_indices[j]
train_set_examples = np.asarray(train_set_examples.append(train_images[random_index]))
train_set_labels = np.asarray(train_set_labels.append(train_labels[random_index])
# Create the MNIST Estimator
mnist_classifier = tf.estimator.Estimator(model_fn=cnn_model_fn)
# Train the CNN model
mnist_classifier.train(input_fn=train_input_fn,steps=train_steps)
# Evaluate the models and print results
eval_result = mnist_classifier.evaluate(input_fn=eval_input_fn)
print("Group Number ",group_number+1,", ANN #",i+1," Accuracy: ",eval_result," %")
#Record ANN accuracy
group_accuracies.append(eval_result)
#record group accuracies in all_accuracies
all_accuracies.append(group_accuracies)
未定义。知道为什么吗?这是我的代码:
客户:
response
服务器:
var tempId;
var request = $.ajax({
type: 'POST',
datatype: 'json',
data: {""},
url: 'file.php?recID=' + recID,
success: function(response) {
console.log(response);
tempId = response.recentId;
}
});
答案 0 :(得分:1)
我刚刚意识到我原来的答案是错误的,因为这样success
回调根本不会被称为 。
实际的问题是您要返回status code 204
,表示“无内容”。 $.ajax()
(和/或底层XMLHttpRequest
)对此表示尊重,并且不会处理任何可用的正文数据。
原始答案:
如果禁用output buffering,则在发送完任何正文数据后就无法设置HTTP响应代码,因为HTTP响应标头不能在HTTP响应正文之后发送。
尝试在发送任何数据之前设置HTTP响应代码 ,例如:
http_response_code($code);
echo json_encode($fdArray);
很可能您的脚本中还有其他错误。例如,$recID
来自哪里?查看您的错误日志。
作为旁注,为什么还不将$recID
绑定到准备好的语句,而不是直接将其插入查询字符串?这是一个安全问题。您已经在使用准备好的语句,因此请正确使用它们。 :)
