我在httpclient 4.3.6配置中使用LaxRedirectStrategy。在DefaultRedirectStrategy类内重定向后，它在DefaultRedirectStrategy类的createlocationURI方法中创建位置。由于非法字符，因此该URL“/harborone0457/Profile%20-%20{0}.aspx”失败。 任何帮助如何解决它。以下是日志

问题是需要对大括号char * binaryBaseChange (char * bin, int size_of_digit) {
int offset = 0;
int i = 0;
int j = 4;
int k = 0;
int number_of_hex_digits = 0;
char* substr;
char * out;
int r = 0;
while(((strlen(bin) + offset) % size_of_digit) != 0) {
offset++;
}
out = malloc((strlen(bin) + offset) / size_of_digit+1);
out[(strlen(bin)+offset)/size_of_digit] = '\0';
r = (int)strlen(bin) + offset;
bin = pad_bin(bin, r);
number_of_hex_digits = (int)strlen(bin)/size_of_digit;
while (k < number_of_hex_digits) {
substr = strndup(bin+i, j);
substr[size_of_digit] = '\0';
i = i + size_of_digit;
j = j + size_of_digit;
if (size_of_digit == 4) {
out[k] = single_digit_bin_to_hex(substr);
} else if (size_of_digit == 3) {
out[k] = single_digit_bin_to_oct(substr);
}
free(substr);
k++;
}
free(bin);
out[k] = '\0';
return out;
}
和char single_digit_bin_to_oct (char * bin_dig) {

return '6';
} else {

return '9';

return 'A';

return 'B';
