jquery ajax发布xml返回错误请求

Question

我目前在以下代码中遇到问题，POST请求返回“错误请求”错误。

CALayer *bottomBorder = [CALayer layer], *leftBorder = [CALayer layer], *rightBorder = [CALayer layer];

CGFloat thickness = 1.0f;
CGFloat side_height = 6.0f;

leftBorder.frame = CGRectMake(0, textField.frame.size.height - side_height, thickness, textField.frame.size.height - 1);
rightBorder.frame = CGRectMake(textField.frame.size.width - 1, textField.frame.size.height - side_height, thickness, textField.frame.size.height - 1);
bottomBorder.frame = CGRectMake(0, textField.frame.size.height-1, textField.frame.size.width, thickness);

bottomBorder.backgroundColor = [UIColor lightGrayColor].CGColor;
leftBorder.backgroundColor = [UIColor lightGrayColor].CGColor;
rightBorder.backgroundColor = [UIColor lightGrayColor].CGColor;

[textField.layer addSublayer:bottomBorder];
[textField.layer addSublayer:leftBorder];
[textField.layer addSublayer:rightBorder];

}

如果我使用完整的URL并且放弃整个“data：orderData”选项，则代码可以正常工作。谁知道问题是什么？
