Question

我在下面的代码处理我的服务器使用套接字发送的响应：

uint8_t buffer[4096];
        int len;
        NSMutableString *total = [[NSMutableString alloc] init];
        while ([inputStream hasBytesAvailable]) {
            len = (int)[inputStream read:buffer maxLength:sizeof(buffer)];
            if (len > 0) {

                NSLog(@"Buffer: %s",buffer);
                [total appendString: [[NSString alloc] initWithBytes:buffer length:len encoding:NSASCIIStringEncoding]];
                NSLog(@"Receive: %@, len: %d",total,len);
                NSLog(@"len: %d, receive: %@",len,total);

}

}

我的服务器发送如下文本文件：

[{"name_user":"stack overflow","user_key":"XXXXXXX","type":21}]

此代码的问题是，如果我发送JSON，控制台日志会显示该JSON的长度。但如果我发送以下JSON：

[[{"name_user":"stack overflow","user_key":"XXXXXXX","type":21}],[{"name_user":"lacrifilm","user_key":"XXXXXXX","type":21}]]

表示控制台日志显示的JSON中的两个值：

Buffer: ~
Receive: ~
len: 184, receive: ~

我认为问题不在我的服务器中，因为如果是这样的话，我会得到：Receive: ~, len: 184，而不是Receive: ~而不是len: 184正如我们在第二次调用{{}}中看到的那样{1}}在上面的命令中。

我该如何解决这个问题？

您正在错误地构建字符串。您正在读取一系列字节，而不是字符串。因此，建立NSString，然后在获得所有数据后创建uint8_t buffer[4096]; NSMutableData *data = [[NSMutableData alloc] init]; while ([inputStream hasBytesAvailable]) { NSInteger len = [inputStream read:buffer maxLength:sizeof(buffer)]; if (len > 0) { //NSLog(@"Buffer: %s",buffer); // can't do this - buffer isn't a null-terminated C-string [data appendBytes:buffer length:len]; NSLog(@"Receive: %@, len: %d", data, (int)len); } } NSString *total = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; NSLog(@"Total: %@", total);。更像这样：

BrowserMobProxyServer proxy = new BrowserMobProxyServer();
        try {
            proxy.start(Integer.valueOf(proxyPool.borrowProxyPort()), InetAddress.getLocalHost());
        } catch (NumberFormatException | UnknownHostException e) {
            Logger.error(e.getLocalizedMessage());
        }
        proxy.waitForQuiescence(30, 3, TimeUnit.SECONDS);
        proxy.setHarCaptureTypes(CaptureType.REQUEST_HEADERS);
        Logger.info("Proxy start status: " + proxy.isStarted());

NSLog显示奇怪的字符而不是JSON
