Mat*_*yhr 21 objective-c nsurlrequest ios wkwebview charles-proxy
我想对我做一个POST请求,WKWebView但是当我用Charles监视请求时,标题没有设置,因此请求失败.这有什么不对？
NSString *post = [NSString stringWithFormat: @"email=%@&password=%@", email, password];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *contentLength = [NSString stringWithFormat:@"%d", postData.length];
NSURL *url = [NSURL URLWithString:@"http://materik.me/endpoint"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:postData];
[request setValue:contentLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[webview loadRequest:request];
这就是查尔斯所说的请求如下:
POST /endpoint HTTP/1.1
Host: materik.me
Content-Type: application/x-www-form-urlencoded
Origin: null
Connection: keep-alive
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
User-Agent: Mozilla/5.0 (iPhone; CPU OS 8_0 like Mac OS X)
Content-Length: 0
Accept-Language: en-us
Accept-Encoding: gzip, deflate
因此,正如您所看到的那样,Content-Length是0,Accept是,application/json并且没有请求正文被发送.
谢谢你的帮助.

我遇到了与WKWebView相同的问题,我决定使用UIWebView来避免iOS 8中的选择器崩溃.我可以想到两种方式:
connection:didReceiveData:和connectionDidFinishLoading:从委托,如果你不使用自签名的SSL证书)创建文件,例如."POSTRequestJS.html":
<html>
<head>
<script>
//POST request example:
//post('URL', {key: 'value'});
function post(path, params) {
var method = "post";
var form = document.createElement("form");
form.setAttribute("method", method);
form.setAttribute("action", path);
for(var key in params) {
if(params.hasOwnProperty(key)) {
var hiddenField = document.createElement("input");
hiddenField.setAttribute("type", "hidden");
hiddenField.setAttribute("name", key);
hiddenField.setAttribute("value", params[key]);
form.appendChild(hiddenField);
}
}
document.body.appendChild(form);
form.submit();
}
</script>
</head>
<body>
</body>
</html>
在您希望加载请求的代码中:
NSString *path = [[NSBundle mainBundle] pathForResource:@"POSTRequestJS" ofType:@"html"];
NSString *html = [[NSString alloc] initWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
WKWebView.navigationDelegate = self;
[WKWebView loadHTMLString:html baseURL:[[NSBundle mainBundle] bundleURL]];
添加方法:
- (void)makePostRequest
{
NSString *postData = [NSString stringWithFormat: @"email=%@&password=%@", email, password];
NSString *urlString = @"http://materik.me/endpoint";
NSString *jscript = [NSString stringWithFormat:@"post('%@', {%@});", urlString, postData];
DLog(@"Javascript: %@", jscript);
[WKWebView evaluateJavaScript:jscript completionHandler:nil];
didMakePostRequest = YES;
}
最后添加WKNavigationDelegate:
- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation
{
if (!didMakePostRequest) {
[self makePostRequest];
}
}

正如OP所述,我在Charles中也确认身体是0字节后webView.load(request).
这个WKWebViewbug 有一个解决方法,我们将POST使用URLSession 发起请求,将服务器返回的数据转换为String,而不是加载url,我们将使用loadHTMLString,它将:
设置网页内容和基本URL.
并且内容是我们转换的字符串:
var request = URLRequest(url: URL(string: "http://www.yourWebsite")!)
request.httpMethod = "POST"
let params = "do=something&andAgain=something"
request.httpBody = params.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { (data : Data?, response : URLResponse?, error : Error?) in
if data != nil
{
if let returnString = String(data: data!, encoding: .utf8)
{
self.webView.loadHTMLString(returnString, baseURL: URL(string: "http://www.yourWebsite.com")!)
}
}
}
task.resume()

这似乎是一个错误.

希望很快就会得到解决.与此同时,恢复到UIWebView或实施Spas Bilyarski在他的回答中提出的解决方案似乎是最好的选择.
我使用这个委托方法,它的工作原理!
#pragma mark - WKNavigationDelegate
- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler{
NSLog(@"%@",navigationAction.request.allHTTPHeaderFields);
NSString *accessToken = @"Bearer 527d3401f16a8a7955aeae62299dbfbd";
NSMutableURLRequest *request = [navigationAction.request mutableCopy];
if(![[request.allHTTPHeaderFields allKeys] containsObject:@"Authorization"]){
[request setValue:accessToken forHTTPHeaderField:@"Authorization"];
decisionHandler(WKNavigationActionPolicyCancel);
[Helper hideProgressHUD];
[webView loadRequest:request];
} else {
decisionHandler(WKNavigationActionPolicyAllow);
}
}
