letstring"line one line two"; 1. 2. 相当于line one\n line two,注意第二行的前导空格还在。 letstring="one line \ written over \ several"; 1. 2. 3. 相当于one line written over several,注意前导空格被忽略了。 letstring="multiple\n\ lines\n\ with\n\ ...
这个lines返回一个迭代器,迭代器的元素是Result<String, std::io::Error>类型的,它们来自request的stream,然后被切割成一项一项的。切割的过程自然是有可能出错的,比如需要转换成字符串,如果这个数据不符合utf-8的编码,那就会出问题了。 然后我们用map迭代这个迭代器,用unwrap将Result<T, E>里的string拿出来。 ...
